Abstract

A dielectric material is a poor conductor of electricity but an efficient supporter of electrostatic

fields and hence store electrical energy. Dielectric materials are also used in various applications

including conventional capacitors to ultra capacitors of modern day. In the era of technology

evolution, the properties for the dielectric materials can be drastically improved paving the way

for new applications to evolve. Latest research reveals that use of nano-composites with suitable

dielectric fillers with polymers as base materials improves the dielectric properties enormously

which could not be realized in conventional dielectric materials. This is the result of high surface

area to volume ratio, small distance between fillers, and bulk interfacial properties which

enhance the ductility with same strength, scratch resistance, hardness and light transmission

characteristics. These properties, of course, depend on particle size of the dielectric filler. In this

review, an overview of the nano dielectric materials, a brief outline of relevant theories on one

front and experimental results on the other front are provided. Few latest experimental results to

demonstrate the improved dielectric properties are presented and discussed. Also, the

nanocomposites as very good EMI shielding materials has been demonstrated. It can be

concluded that nano dielectric materials are considered highly potential and promising insulating

materials of the future with wide open application domains.

Abstract

The aluminium based metal matrix is used as light weight components in the manufacturing

industries and is popular for its low density and high stiffness. Various reinforcing materials

like Silicon Carbide, Aluminium Oxide, Graphite and CNTs are best suitable for aluminium

based metal matrix composites. In this paper, we are presenting the comparison study of

fabrication of Al6065 alloy composite with MWCNT by stir casting technique. This alloy, with

and without SDS coated CNT is used to investigate the dispersion characteristics. The presence

of low molecular weight surfactant was investigated by FT-IR. About 1% of CNT composite

is used as a filler metal and the dispersion of SDS coated and Non-Coated CNT is examined

by Scanning Electron Microscope (SEM). In comparison with the Non-SDS coated CNT, the

one coated showed good dispersion stability in the fabricated composite with increase in the

hardness of the reinforced metal.

Abstract

In the modern world, the polymers and composite materials find a wide range of applications.

In the real-world environment, the damages in the components can’t be avoided due to expose

to the dynamic environment. This damage can occur, internally or externally at the microscopic

level, which can’t be noticed with bare eyes. These microscopic damages can further lead to

failure of the product. This can lead to losses in factors such as components, products and other

resources. Based on the idea of self-healing capacity of tissues present in the living beings,

researchers have developed self-healing polymer composites, which have the inherent ability

to give solution to heal the internal cracks or damages automatically or non-automatically

with/without any external intervention. This present paper portrays a brief review of self-

healing material in the polymer composites on self-healing mechanism, advantages, limitations

and applications in the field of aerospace, automobile, coating of the material, electronics,

energy sector and many more.

Keywords: Polymer composites, Epoxy resin, Self-healing materials.

Abstract

Composite structures are widely used in aerospace, automobile and transport sectors. Even

though their performance and reliability are very high, there is a major problem for disposal

after their service life. Plastics and synthetic fibers are major concern and threat to

environment. Recycling is a biggest problem because it cannot be used again for critical

components due to loss in strength and technology development for recycling is not up to the

mark. Therefore, there is an increase in tendency to use natural fibers at least for secondary

structures like panels, boards, doors and cockpit dashboards etc. but natural fibers have the

problems of atmospheric degradation and their weak interfacial bonding with resin. In the

present paper, studies are conducted on glass-jute hybrid composites to explore possibility of

using jute fibers in glass fiber composites. Samples were fabricated with different proportions

in layup process. These specimens are subjected to bending, ILSS, moisture absorption and

flammability tests according to ASTM standards for conforming for application to secondary

structures. The moisture absorbing and flammability tests conducted will be useful to predict

how these composites behave in case of fire and extreme humid conditions. Also, the results

show that adding jute fibers to glass there will be improved stiffness and shear strength

properties

Abstract

MMCs are considered as potential materials for multiple applications due to their unique

physical and mechanical properties. For further improvement in the strength of the material, its

low density, stiffness, wear and creep properties can be improved by addition of

reinforcements. It has been observed that improved strength, stiffness and wear resistance in

most metal matrix is, by addition of particle reinforcements such as Graphene, CNTs and SiC.

The characterization of these new materials is essential for their intended applications.

Micromechanics methods and finite element methods are two most prominent methods to

predict the mechanical properties of new materials and thus avoiding the laboratory cost. This

paper reviews the effect of various reinforcements on MMCs through micromechanical and

FEM analysis. The various algorithms adopted in micromechanics are also discussed in detail.

The behaviour of interface in reinforced metal matrix is also discussed in this paper.

Keywords: MMCs (Metal Matrix Composites), CNTs (Carbon Nanotubes) and SiC (Silicon

Carbide).

Abstract

High strength to weight ratio and several mechanical, thermal and recycling properties makes

aluminium as ideal choice for various applications in industrial sectors like automotive,

beverage containers, aeronautics and constructions. During casting process, due to improper

solidification the defects like porosity, pits etc are formed in the metal. This casting defect

reduces the mechanical properties of the material. In order to enhance mechanical properties

processing of metal is required. One of the processing techniques suitable for this is Friction

Stir Processing. In this work, we have used FSP to synthesize aluminium matrix composite

reinforced with polymer derived ceramic. For the resulting composite the properties like

microhardness, tensile strength was studied for four and six passes and compared with the base

metal. The hardness for the processed material increases three times and four times for four

and six passes respectively, when compared with the base metal. The results showed that with

the increase in the number of passes, the tensile properties of composites including ultimate

tensile strength and yield strength were improved.

Corresponding author E mail: [email protected]

Abstract

Resistance heating furnace is a device where heat energy is generated by creating resistance to

the flow of electrons through an element (a good conductor for electricity as also for heat), thus

due to high friction, a temperature is developed and heat the charged materials. High

temperature resistance furnace, in the conventional systems, regarding manufacturing,

insulation, temperature controlling (while heating to desired high temperature 1800 degree C,

or above), cause tremendous thermal losses or becomes very bulky and costly affairs. Though

concept of high temperature resistance furnace’ is quite old, but, recent development of

material science has created a radical change in the aspects of manufacturing process, in the

concept of insulation, concept of control systems and in design of heating system astonishingly.

Considering all the new – age developments, present proposed work is outlined specifically to

meet the requirements of “high and low temperature furnace with compound heating system

(using three different types of heating elements, namely Kanthal A1, silicon carbide-SiC and

molybdenum di-sillicide-MoSi2 to raise working temperature of furnace up to 1800 degree C).

A new design is to arrest thermal losses to minimum, using improved insulation to improve

thermal efficiency, and with latest control systems (PID programmable type). The goal of this

experiments is to achieve optimum thermal efficiency with skin temperature equal to the room

temperature, to achieve accurate results in terms of resolution and sensitivity, and for

continuous operations for various heating processes requiring temperature rise from ambient

temperature up to 1800 degree C, also in multiple ranges to be followed continuously one after

another, for wide range of applications as laboratory furnaces, testing equipments within

temperature 1800 degree C and above. The present experiment will be a great mileage ushering

new era for research in the field of thermal engineering in coming years.

Keywords: Resistance furnace, maximum working temperature 1800C, zirconium insulation,

Abstract

The use of materials like asbestos and metals such as aluminium are being used from ages.

Over the period, advancement in engineering has led us to various materials which provides

several different advantages over the former. In modern era life has transformed and the needs

of people have changed dramatically. As we move towards the new era advanced materials

should cost less. Jute, coir and rice husk fibres are biodegradable material which has no adverse

effect on environment. These natural fibers are abundant in quantity having low cost and ease

in availability. With this the use of materials like bone powder, tooth powder can also improve

the properties at the surface. Although materials like asbestos and several metals are available

possessing optimum strength their use comes with certain disadvantages and cost issues with

very less opportunities of recycling whereas being biodegradable materials makes the

composite quite repairable and recyclable. In this study an investigation has been carried out

to make use of coir and jute with epoxy resin to form a polymer composite material with

enhanced mechanical properties. Composites formed are more reliable and sustainable

compared to the conventional one and partially eco-friendly.

Abstract

Graphite foam with extremely high thermal conductivity has been investigated to enhance heat

transfer of latent heat thermal energy storage (LHTES) systems. However, the use of graphite

foam for elevated temperature applications (>600oC) is limited due to poor oxidation resistance

of graphite. In this proposed research, oxidation resistance of graphite foam coated with silicon

carbide (SiC) is to be investigated. A pre-ceramic polymer derived coating (PDC) method is

planned to be used to form a SiC coating on the graphite foams. Post coating deposition, the

samples are to be analyzed by scanning electron microscopy and energy dispersive

spectroscopy. The oxidation resistance of PDC-SiC coating is quantified by measuring the

weight of the samples at several measuring points. The experiments are to be conducted under

static argon atmosphere in a furnace. After the experiments, oxidation rates (%/hour) were

calculated to predict the lifetime of the graphite foams.

Abstract

This paper presents corrosion studies carried out on Silicon Carbide reinforced Al metal matrix

composites subjected to cold forging. Al/SiC composites were fabricated using stir casting

process for 2%, 4% and 6% weight percentages of SiC. The corrosion studies were carried out

for test variables - normality of solution, weight % of SiC and corrosion duration for as cast,

single and double forged conditions. The specimens were tested in NaCl solutions of normality

of the 1.0, 1.5 and 2 and the exposure period ranging from 40 to 90 days. From the studies it is

observed that, there is an appreciable decrease of the corrosion rate and weight loss per unit

area, which was observed to be severe in the initial stages. This phenomenon of decrease of

corrosion rate with exposure time were attributed to possible passivation of matrix alloy with

the formation of protective layer formed on the specimen exposed to NaCl protecting the base

metal from aggressive environment. Irrespective of weight % of SiC reinforcement the

corrosion rate is increased with the increase in concentration of NaCl. Increase in weight % of

the SiC particles lead to decreased corrosion rate than that of the matrix alloy. The corrosion

morphology indicated pit formation, preferentially corresponding to SiC clusters and the

formation of pits on the surfaces were found to increase with increase in the percentage of SiC.

It was found that corrosion loss is very less and significantly improves corrosion resistance in

forging conditions.

Abstract

The Metal matrix composites (MMCs) are of great interest in industrial applications for lighter

materials with high specific strength, stiffness and heat resistance. In MMCs, aluminium-

matrix composites reinforced with discontinuous reinforcements are very attractive because

they give the best combination of strength, ductility and toughness and they can be processed

by conventional methods such as rolling, forging, extrusion and as a final process, machining.

In the present investigation Al-4.5wt.%Cu alloy is chosen as matrix reinforced with fly ash and

B4C by squeeze casting technique. The composite of 2wt.% and 4wt.%fly ash with 2, 4, 6wt.%

B4C were reinforced in Al-4.5wt.%Cu matrix. The composites fabricated by squeeze casting

were hot rolled at different reductions of 0, 8, 16 and 25%. The results showed improved

hardness, tensile strength till 16% reduction; whereas wear resistance is higher for minimum

percentage of reinforcement with increase in extend of rolling. Higher weight percentage of

reinforcements with higher reduction results in shrinkage cavities and particle cracking during

rolling.

Abstract

Calcium Phosphate Cements are brittle biomaterials of low bending strength. Since their

discovery in the 1980s, extensive research has been conducted to improve their properties, and

emerging evidence supports their increased application in bone substitute material. Much effort

has been made to enhance their mechanical properties of these cements by reinforcement with

fibres. Altering particle size distribution in conjunction with using liquefiers reduces the

amount of cement liquid necessary for cement paste preparation. This in turn decreases cement

porosity and increases the mechanical performance, but does not change the brittle nature of

the cements. In this process we introduce a new class of composite that is reinforced with

titanium and aluminium alloy wires. Bending strength and ductility of the composites increased

with aspect ratio and volume content of the reinforcements. Reinforcement with metal and

polymer fibers (PLA) further improved the qualitative fracture behaviour and gave indication

of enhanced strength and ductility. Calcium magnesium phosphate cement (CMPC) reinforced

with titanium wire as reinforcement is having compression strength of 52 mpa. Flexural

strength of CMPC reinforced with titanium wire is of 35 mpa. X-ray diffraction and SEM

techniques are used to characterize the structure of powders with or without physiological

conditions, it was found that the CMPC contained cylinder-like crystals and clay-like

substances to form a dense structure, and the crystals were in close proximity to each other.

Prediction of Impact Damage Resistance on Laminated

Composites using Single-shell Modelling approach.

1Vinay Bashettiyavar, 2S B Manjunath 2 Professor, Department of Mechanical Engineering, DSCE, Bengaluru, India.


Abstract

Composite materials are formed by combination of two or more materials that are combined

at a macroscopic level which are not soluble in each other and retain their characteristics when

combined to achieve required properties. Fiber-reinforced composites are known for their

versatile properties such as, high strength to weight ratio, high stiffness to weight ratio, high

impact strength, high fatigue resistance, etc. Hence they are most commonly used in aerospace,

automotive, marine structures and defence sectors. Composites have high strength in the

direction of fiber, lesser in strength in transverse direction. Transverse loads cause Barely

Visible Impact Damage (BVID) which results in catastrophic failure of composites and

structure. BVID has been the topic of continual research due to its complexity in early detection

and prevention. Composite Stiffened Panels are widely used in the modern aircrafts structure,

which has the advantage of light weight, structural efficiency and good crack performance, but

they have lesser performance in thickness direction, especially for low- velocity Impact. Hence

an extensive study of Impact behaviour with barely visible damage is necessary.

In present study Low-velocity impact response and damage analysis of simple CFRP laminate

and stiffened CFRP laminate using finite element modeling with LS-DYNA has been studied.

Keywords— Composite, Composite stiffened Panel, Impact response, Impact damage, Barely

visible impact damage.

Abstract

A composite material is a made from two or more constituent material with significantly

different physical or chemical properties that, when combined produce a material with

characteristics different from individual components remain separate and distinct within the

finished structure, differentiating composite from mixtures and solid solution. The new

material may be preferred for many reasons; common examples include materials which are

stronger, lighter, or less expensive when compared to traditional materials. Natural fiber

composites are a class of materials which are currently replacing the synthetic fiber composites

for practical applications. This paper deals with the fabrication and investigation of hybrid

natural fiber (wood powder) composites. The following properties can be improved by forming

a composite material: tensile strength, stiffness, non-corrosive, wear resistance, flexibility, high

durability, thermal insulation. Mechanical characterization of the natural composite is obtained

by testing the composite lamina for tensile, shear, and impact strength. Chopped Glass fiber is

used, which is mixed with wood powder for different model with different percentage, which

improves the adhesive property and adds strength.

Abstract

Composite in composite material means, two or more materials combined on a macroscopic

scale to form a useful material. The advantage of composite is, they exhibit the best qualities

of their constituents and also some qualities that neither constituent possesses. Compared to

particular metals, advanced composites have greater arduousness and good strength but with

lesser density. These properties make advanced composites extremely attractive and purposeful

in situations where component weight is critical. Fibers from natural and man-made sources

are used to make composites. The following experiment was conducted, to develop mechanics-

based experimental approach to estimate the thermal and mechanical properties of composites

made according the hand layup technique. The study is done on composite materials produced

by reinforcing natural fibre i.e., sugarcane bagasse. Epoxy and hardener are used as binding

agents. The composite was also embedded with varied amount of ash content (5, 10, 15, and

20%). It was then subjected to various tests for characterization. The higher percentage of ash

content in the matrix is known to give a higher resistance to heat, a property that can be

harnessed to tolerate friction heat in extensive mechanical work. The composite material can

be utilized in the field of automobiles, false ceiling, flooring of buildings, pavements etc. They

are also environmentally friendly and economical.

Abstract

Metal Matrix Composites (MMCs) have emerged as an important class of materials for

structural, wear, thermal and electrical applications, primarily because of their superior strength

to weight and strength-to-cost ratios when compared to equivalent commercial alloys. The

properties of metal matrix composite depend on the matrix material, reinforcement material,

reinforcement particle size, composite fabrication method, etc. The aluminium based matrix

composites (AMC) have the potential to offer desirable properties, including strength, high

specific stiffness and excellent wear resistance that make them very attractive for numerous

applications in aerospace, automotive and military industries. Because of its low density, low

melting point, high specific strength and thermal conductivity, aluminium has been reinforced

with a wide variety of ceramic particulates such as Al2O3, SiC, TiB2 and TiC. Among these

particulates, TiC and Al2O3 have emerged as outstanding ceramic reinforcements because of

their prominent mechanical, electrical and optical properties and wide range of applications.

The present work mainly focused on the preparation Al/TiC metal matrix composite by adding

Titanium carbide particles in different weight percentage to Al6061 alloy through stir casting

technique. Titanium Carbide particles were incorporated in to aluminium alloy with varying

proportions from 3% to 12% in the steps of 3% by weight. The cast composites were further

processed in secondary manufacturing method by extrusion process to enhance the properties.

Different tests were carried out to evaluate mechanical properties such as ultimate tensile

strength, ultimate compression strength, impact strength and hardness. It is observed that the

strength and hardness of the composite increased with the increase of reinforcement and

extrusion process further enhances all the properties.

Abstract

Now-a-days renewable energy source has become an important source of power generation

due to the fast depletion of fossil fuels. Power generation due to wind is one of leading

renewable sources of energy. This work will illustrate a new concept of power generation

using bladeless wind turbine. Advantages of bladeless wind turbine are majorly the absence of

moving parts, so the friction loss will be low and also, it is eco-friendly. We use traditional

wind turbines to produce energy, but the production cost is high and many disadvantages like

capital cost, maintenance cost, running cost, friction loss etc. In this work, we generate

electricity by using the bladeless turbine on the principle of “Vortex effect”. It will generate

electricity with the help of oscillation or vibrations produced due to the flowing of wind. It

works on the principle of vibrations. Here the electricity is generated by using linear generator.

The working principle is simple, when the air strikes the oscillation member; the vibrations are

produced and these are converted into reciprocating motion in generator. Hence the electric

voltage is produced by the linear generator and power is stored in batteries via capacitor.

Abstract

An excavator is a typical kinematic linkage which consists of four links namely body, boom,

stick and a bucket. It consists of revolute joints and controlled by hydraulic cylinders. Joint

angles are functions of length of the actuator. Replacing the bucket with some other

attachments, the excavator can be made multi-purpose so as to perform several operations such

as digging, material handling, demolition, crushing, cutting etc. The tip of the bucket is used

for digging operation. Digging force exerted by the tip on the ground depends on the orientation

of the bucket and transmission angle. Magnitude of digging force varies with directions at

general configurations. The forces adversely affect the excavator, sometimes leading to severe

damages of mechanical components during operation. At isotropic configuration, forces of

uniform magnitude can be exerted in all directions on the ground. It is possible to maximize

the digging force and minimize the effort at isotropic positions. Hence, it is essential to

optimize the design of excavator linkages based on the concept of force isotropy. The study

focuses on isotropy of commercially available wheel based JCB-3DX excavator. Link

parameters required for the simulation are normalized with respect to boom link length. It has

been showed that, a non-isotropic excavator can be modified into isotropic one, by changing

the link parameters. Showed that an excavator used for digging or rock breaking applications

may be redesigned to exploit benefits of isotropy. This configuration will help to apply a

uniform force on the object while breaking in any directions. This method not only improves

the energy efficiency but also increases life of end effector of manipulator.

Abstract

This paper presents the solution methods of kinematic analysis of planar mechanisms. The

procedure is to write programs that solve and plot displacement, velocity, and acceleration of

the desired point on the coupler link. The method is based on points of intersection of two

circles and points of intersection of the circle on a line. The analysis is performed by using

built-in functions and graphics tools of MATLAB software that is optimized for accurate

solutions. The results of the program are compared with analytical and graphical methods. The

examples of four, six and eight bar mechanisms are presented here. The possibility of extending

the method to mechanisms having different linkage combinations is outlined. The advantage

of this method is the simplicity in implementation and a clear understanding of the behavior of

the linkage mechanism

Abstract

The quest for an engine to increase mileage has started before many years. Many automobile

manufacturing industries are doing more research on how to increase mileage of vehicle. In

today’s automobile competition every manufacturer is focusing on weight reduction of vehicle

by considering this objective, this paper focuses on providing alternative material. The

objective of the present work is to optimize weight reduction to increase mileage of vehicle.

Saving grams at different parts in a car helps us in saving some kilograms at the end of the

design. The focus of this paper is on weight reduction of Crankshaft. Crankshaft is one of the

essential components for the effective and precise working of Internal Combustion engine with

the complex geometry; which converts the reciprocating displacement of the piston to a rotary

motion. Here a thorough study is made for single cylinder four stroke petrol engine crank shaft

for selection of best suitable material. The Design of crankshaft is made as per the calculated

specification by using Solid edge V19 software. This model will be converted to Initial Graphic

Exchange Specification (IGES). Finite element analysis (FEA) is performed in ANSYS

software to obtain the variation of stress magnitude at critical locations of crankshaft by

applying boundary conditions as the sides fixed and pressure spectrum is applied in the middle

of crankpin. Then, the Static simulation has to be conducted on the crankshaft with three

different materials Structural steel, 4340 Alloy Steel and 300M VAC-ARC steel which are used

in our project work. Analysis results are compared with theoretical results of von-misses which

limits to validate the model.

However, as the groundwork of study and the analysis are the same for multi-cylinder engines,

the methods used could be altered and implemented for crankshafts from alternative varieties

of engines. The geometrical changes in the size of the crankshaft along with a change in

material of the crankshaft are considered as a potential source for reducing the weight and cost

of the crankshaft.

Abstract

There are different control systems for a gear change control apparatus for an automobile and

there are some controlling methods for that gear shifting mechanisms. The rotational output of

the engine is transmitted to the drive wheels via clutch and gear box. When the gear is shifted

up, the speed ratio will vary as well as the load capacity. The rotational output will increase as

per the gear shifted. The rotational speed will decrease when the gear is shifted down. In this

work, we have two electro magnets which are coupled to the ends of the gear rod. Also, this

will be actuated by two buttons which will be placed near the left hand. The electric supply is

given by the separate battery to the coils to actuate the electro-magnets. When the coils are

energized, the magnetic field pulls down the coil to change the gear ratios as per the

requirements. This avoids confusion to the rider and also gives comfortable ride while driving

through hilly region. This mechanism also helps for the physically challenged persons, who

have to shift the gear ratio by hands. These are also meant for the beginners and women who

have fear of riding the bikes.

Department of Mechanical Engineering, Sapthagiri college of Engg. Bengaluru-57

Abstract

As the need of power requirements are increasing by many folds, more studies on renewable

energy sources are being made and innovative methods have been thought of to generate

electricity by unconventional methods. In this regard an attempt is made by us in harvesting

energy absorbed during the vehicle movements over speed bumpers on roads.

This work concentrates on extracting kinetic energy of vehicles that run on the streets and to

generate power from the same. The arrangement consists of a flexible curved portion

resembling a road hump that can be conveniently installed beneath the hump. As the vehicle

movements exert pressure, the same is utilized to increase the pressure of air contained in a

cylinder. The high-pressure air is then made to impinge on turbine blades with a kinetic energy

when passes through a nozzle. This develops mechanical rotational energy which in turn can

be converted in to electrical energy.

The performance tests conducted after the installation has shown that power developed and

thereby stored in battery is sufficient to run electrical appliances used for domestic purposes.

The developed system is one of the innovative methods of power generation as producing high

pressure air needs no fuel and power generation is possible out of energy which otherwise

would go as waste.

Abstract

Cashew is one of the main potential fruit, in which both the fruit and cashew nut are useful.

Traditional method of cashew seed separation from the cashew apple is time consuming and it

requires human power. Cashew seed separator machine was designed and fabricated to easy

the work of farmer. At present, these cashew apples are either used as a fertilizer to the cashew

plant or thrown away as garbage. This project aims at reducing the human labor and time

involved in the traditional way. In a short duration of time the machine can convert large

quantity of raw materials into acceptable final products. The machine is manufactured from

locally available materials and assembled and maintained at a relatively low cost. This

mechanism is connected to the two flat plate one is fixed and other is movable. These movable

plates which is connected to the rack and pinion mechanism moves to and fro motion. At that

time knife edge separates the cashew nut from cashew apple. At the bottom of movable plate

collects the cashew nuts and top surface of the fixed plate collects the cashew apple. So, in this

machine we can perform the operation with less time & reduced man power also cashew fruit

is not damaged. The separated fruit is used as fodder for cattle.

Abstract

In older days filling and packing was done manually, a person had to weigh the product using

some means like weigh balance and then fill it to a bag and then pack it. This takes lots of

labour and time is the key factor in the mass production as well as in batch production. To

reduce the man power in packing field & to increase the productivity this concept has been

developed as a dehusked areca nut bagging and packing machine. Compare to other type of

packing machines available in the market are costlier so we designed a machine that can

perform both filling and packing operations with low cost. It consists of, frame, joints, bearing,

stitching machine etc. This machine is basically designed for packing of dehusked areca nut.

With the help of this machine we can pack the dehusked areca nut easily by consuming less

time and also human effort. Generally, we can see different packing machine in market for

various application but they are not economical in the market. In this setup dehusked areca nut

is filled in bucket using pulling the machine forward. Hooper is the container in which

dehusked areca nut is collected. Areca nut is then directly filled to the bag through the Hooper

which fills the areca to the bag until the required weight is achieved for pre-defined weight.

Then the series of bag is packed one by one using packing machine. So, in this machine we can

perform both bagging & packing operations simultaneously so that reduce man power used for

the process also less time consumable as compare to manual processes.

Abstract

The existing single screw press expeller can process only 25 – 30 kg of Pongamiapinnata seeds

per hour in three or more passes, with low oil yield of about 18 percent. The increase in

demands cannot be met by a machine with this low yield. Hence, this project was aimed to

design and develop an oil expeller which meets the increased demand by increasing the

productivity of the expeller. In response to the defined limitations of existing technology,

various concepts were generated such as flourmill, sequential type, reverse worm and twin

screw. Worm concept and results were obtained with increasing yield but also with

increasing retention time. Depending on the various deciding factors, the concept was

screened for the further development. Preliminary experiments on Twin Screw extruder were

carried out to understand various difficulties in oil expulsion and conclusions drawn from these

experiments led to the design of twin screw oil expeller. By considering various factors such

as throughput, power requirements and material selection, the detailed design of machine is

started. It includes twin screw shaft designs, Barrel designs the project objective, and twin-

screw concept was selected.

Abstract

Automated floor cleaning machines are commonly used in developed countries because of high

cost of labour, time, efforts, and affordability. The concept is not popular in developing or

emerging countries. Reasons for non-popularity are cost of machine and operational charges in

terms of power tariffs. In India, especially in summer, there is power crisis and most of the

floors cleaning machines are not used effectively, due to this problem, particularly in

commercial applications. Also, with the advancement of technology, automated floor cleaning

machines are getting more attention of researches to make life of mankind comfortable.

Since cleanliness is an important factor, it is very important to maintain public hygiene. In our

project, automated floor cleaning machine is proposed keeping in mind the basic considerations

of low cost and easier to handle.

The floor cleaning machine consists of various components like scrubbing disc, mopping pad,

vacuum pump, relay switches, microcontrollers, circuits, etc. The main focus is on reducing

the cost and making it easy handling with less effort. Also, one other important thing is that

cleaning different types of floors is also important to note since the design of the machine varies

according to complexity of the cleaning requirements.

Bengaluru, 562157, India

E mail: [email protected]

Abstract

Fatigue is the progressive, localized, permanent structural change that occurs in materials

subjected to fluctuating stresses and strains that may result in cracks or fracture after a sufficient

number of fluctuations. Fatigue fractures are caused by the simultaneous action of cyclic stress,

tensile stress and plastic strain. If any one of these three is not present, fatigue cracking will

not initiate and propagate. The cyclic stress starts the track; the tensile stress produces crack

growth. Although compressive stress will not cause fatigue, compression load may do so.

In this work, with the help of simple mechanisms a low cycle constant amplitude fatigue testing

machine is designed and fabricated as per ASTM E606 and E467 Standards procedure for

fatigue testing. A repetitive bending load is used for the fatigue testing which is different from

conventional or available fatigue testing machine.

Abstract

Modelling of a car bumper is done using CATIA V5 R19 and analysis is done in hyper mesh.

Impact analysis is done on the car bumper for the impact force of 200 N. The analysis is carried

on the car bumper for Mild Steel. The density of Mild Steel is much more than aluminium,

carbon fibre epoxy and s2 glass epoxy; thereby the overall weight of car bumper is high. By

observing the Impact Analysis results like stress and displacement, the stress values is very

high for Mild Steel. Factor of Safety measured in impact analysis for Mild Steel is observed to

be very high, higher than the optimum range used in automobile industries. In twisting analysis,

the stress and displacement of the bumper is observed and found that the stress obtained is very

high and thus the factor of safety measured is also high. Thus, from the analysis we can

conclude that the material used for modelling of bumper increases the weight and cost. Though

the material used is safe but is not a favourable material to be used for bumper modelling in

terms of weight and cost. Thus, most of the automobile industries use a combination of

Polycarbonate (PC) and Acrylonitrile Butadiene Styrene (ABS) called PC/ABS for modelling

most of the parts of the automobile.

Abstract

Solar energy is fast becoming a very important means of renewable energy resource. With solar

tracking, it will become possible to generate more energy since the solar panel can maintain a

perpendicular profile to the rays of the sun. In This paper the main objective is to design of

solar tracking system that has single axis of freedom. Wind Anemometer is used to protect

solar panel from wind blowing at a speed of 60kmph and night LDR sensors to stop rotation

during night. The control circuit is based on a PIC Microcontroller PIC18F46K22. It is

programmed base on time to actuating the stepper motor to position the solar panel.

The solar panel is positioned where it is able to receive maximum light. As compared to other

motors, the stepper motors are able to maintain their torque at high speed. They are also more

efficient with efficiencies in the range of 80-90%. Stepper can supply roughly twice their rated

torque for short periods. They are also quiet and do not vibrate or suffer resonance issues. And

can rotate in both clockwise and anti-clockwise direction. Performance and characteristics of

solar panels are analysed experimentally. It is cheaper, less complex and still achieves the

required efficiency. We use in terms of costs and whether or not the system is supposed to be

implemented by those that use solar panels, the system is viable. The increase in power is

considerable and therefore worth the small increase in cost. Maintenance costs are not likely to

be high.

Abstract

Footstep air conditioning system works as an alternative to regular air conditioning system.

Here we use the kinetic energy generated by a person’s body weight to compress the

compression spring. This process compresses and rises the temperature of the intake air. The

compressed air is then stored in a storage tank. A flow control valve prevents the back flow of

the air to the piston-cylinder arrangement. Further, the air is passed through the chiller for heat

exchange process. Here, water is used as a coolant. To maintain the coolant temperature a

peltier plate is used to constantly remove the excess heat with the help of a heat sink (cooling

fan with fins). In the heat exchanger, the heat from the air is transferred to the coolant without

coming in direct contact with each other. The coolant is re-circulated while the required cool

air is sent out of the heat exchanger.

Foot-step air conditioning system consumes less electrical energy when compared to regular

air conditioning system.

Abstract

The main aim of the project is to design a weld fixture for carrying out welding of Gas bottle

mounting flanges to the shell sub assembly of GSLV MK III propellant tank”. The project work

deals with the design, realization of the welding fixture and implementing it in the actual flight

hardware. The tank is made up of AA 2219 material and the process employed for joining of

Gas bottle mounting flange to the shell is double pass pulsed DCSP TIG welding process. For

this purpose, an exclusive fixture is to be designed which consists of weld back-up, clamping

mechanism and purging system etc. During design of weld fixture other aspects such as

clamping & unloading mechanisms, shrinkage, heat sink effects etc. are also to be considered

to obtaining a sound weld. The fixture design should be of compact and simple in configuration.

It shall also include features such as easy locating, rigid clamping in the correct position to

achieve minimum weld mismatch and distortions. Achieving above requirements over a large

diameter of about 4m class is practically difficult without a proper fixture in place.

Abstract

Fixtures play an important role within many manufacturing processes. They accurately locate

and secure a workpiece during machining such that the part can be manufactured to design

specifications. Thus, fixtures have a direct effect upon machining quality, productivity, and the

cost of products. The present paper explores the design and development of hydraulic fixture

for real industrial component. The operations to be performed are rough and finish milling of

flange, drilling, reaming & spot facing on VMC. In existing design, the fixture set up is done

manually, so the objective of the research is to replace with hydraulic fixture to save time for

loading and unloading of component. The evaluated fixture uses hydraulic vertical swing

clamps for holding the work piece driven by hydraulic power pack. Thus, the new fixture

achieves automatic and simultaneous clamping of parts.

Abstract

The main aim of the project is to design a windmill that operates without generator and ball

bearings and to get maximum power output. The use of wind energy for energy generation is

one of the oldest methods for harnessing renewable energy. Use of renewable energy is an

essential ingredient of socio-economic development and economic growth. A vertical axis

wind turbine (VAWT) is introduced by magnetic levitation technology to optimize the

performance. The system utilizes nature of permanent magnet as a replacement for ball

bearings to levitate the turbine component and thus minimize energy losses while rotating,

which is the major problem that furthermore, the system can be suited by conventional wind

turbine. The Maglev Wind Turbine is expected to bring wind power technology to the next

level. Furthermore, the system can be suited in use for more rural and urban areas of low air

speed regions. The selection of magnet materials in the design of wind turbine system will be

discussed. A model of wind turbine is built to perform several tests such as starting speed,

rotational speed at constant wind speed, and time taken to stop rotation completely. The results

obtained will be compared with the model of conventional wind turbine. Power will then be

generated with an axial flux generator, which incorporates the use of permanent magnets and

a set of coils.

Pavan kumar SM1,*, Pruthvi MJ2, R Vishnu3 123 Student, Department of Mechanical Engineering, JSSATE-B, Bengaluru-560010


Abstract

A turbojet engine is an engine that accelerates a fluid into its surrounding environment to form

a fast-moving jet. The reaction felt by the engine to this explosion is the thrust force, which

acts in the opposite direction to the jet. A turbojet engine is an assemblage of five important

components with a compressor coupled to a turbine, combustion chamber, diffuser, nozzle and

hydrostatic bearing. All the components when assembled together form what is called as a

turbojet engine. The purpose of this project is to analyse the various aspects of a jet engine like

thrust, efficiency, and overall performance when propelled by alternative fuels and the various

design aspects of the model which effect on the performance. For this purpose, a working

model of a turbojet engine is built using an automotive turbocharger which serves as an

integrated turbine and compressor assembly and other components like the combustion

chamber, nozzle and ignition system are fabricated and the final model is used to analyse the

different aspects mentioned above and results are formulated. Our results indicate that rotor

inlet, equivalence ratio, and combustion chamber design are a significant variable in most of

the relationships. Design of combustion chamber and the method of entering the primary and

secondary air have an essential role in the completed combustion process and the jet engine

speed. Using bio gas for completely propelling the engine will not be feasible and hence a

mixture of LPG and bio gas were introduced and the results are formulated for the output like

thrust, efficiency and overall performance.

Abstract

For sorting object in industry optical sorting is very much convenient. Colour and size are the

most important features for accurate classification and sorting of product which can be done

by using camera (machine learning) and analyzing their pictures. An automated sorting

machine is a device which takes image of an object, analyze it and assert them into a different

belt conveyor. When object moves from conveyor belt to rotating disc, a pre fixed camera acts

as input device and will send signal to processing unit where it acts as the controller which will

give command to the pneumatic actuator to do the action. Depending on the image, they are

placed on the respective carriers automatically where these carriers dispatch them to the

corresponding destinations. This gives a provision to reduce the manual effort and hence

human error by replacing the conventional methods of sorting in areas involving hectic sorting.

The system comes into play in airports and other industrial distribution centres where the

products or commodities have to be sorted into batches in order to take them to their respective

destination.

Bengaluru-560060, India


Abstract

Innovation in the field of industrial automation is a new challenge in today’s fast-growing

automation technology. Design of sorting methods of products in an industry is a tedious

industrial process, which is generally carried out manually. In order to sort objects, we need to

be able to gauge the size of the object. Continuous manual sorting creates quality consistency

issues. Segregation of objects can be based on different characteristics like weight, colour, size,

and shape, weighing and then separating. In this project, the proposed conveyor belt system is

intelligent in detection and sortation. The conveyor system acts as a normal one but has the

intelligence to sort through objects based on their height. It uses an IR sensor which detects the

object’s height and directs the microcontroller to sort the object into the appropriate bin. The

conveyor belt is made ‘smart’ by using an IR sensor to detect whether an object is placed on it

or not. Accordingly, the conveyor belt starts only if an object is placed on it thereby, helping

to conserve electricity. This ‘smart’ feature in the conveyor system helps to reduce the

manufacturing overhead of the industry. The automation-based system contains efficient

sensors for sensing the objects based on height, thereby, helping the industry immensely in

decreasing the cycle time of a product.

Abstract

This is an era of automation where it is broadly defined as replacement of manual effort by

mechanical power in all degrees of automation. The operation remains an essential part of the

system although with changing demands on physical input as the degree of mechanization is

increased. The existing pick and place are used to perform pick and place the components on

the assembly line. These components are similar in their shape and size. In this project we are

going to design pick and place pneumatic system to handle different shape and size and also

irregular objects. The existing device had a greater number of actuators and mechanisms are

used to perform the pick and place operation. Hence, it’s become so expensive. Our material

handling system consists of four cylinders, all are of double acting the cylinder is used to

actuate rack and pinion assembly, piston rod of cylinder is connected to rack, which is meshed

with the pinion. By operating the cylinder1, rack and pinion turns the whole assembly for 260

degree. By varying the length of the rack, the turning angle can be altered. Vertical cylinder is

used to increase the height of the setup. The height is limited to piston rod length. Horizontal

cylinder is used to increase the arm length, the working area of the arm is limited to length of

the piston rod length. Gripper cylinder is used to actuate the gripper. Our material handling

system consists of four pneumatic actuators and single rack and pinion mechanism, within this

we can able to achieve the existing results. While comparing to the existing robot cost, it is

very less. Finally, our pick and place robot can able to perform the pick and place the irregular

components on 260 degree within the workspace.

made negative effect on the environment. Apart from this, sometimes Oil is getting spillage as

the result of chronic and careless which is used in the oil industries on oil products. It is

estimated nearly 706 million gallons of waste oil enters into the ocean every year; and more

than half is from land drainage and waste disposal. This made ever lasting damage to aquatic

life. In order to separate the oil from oil water mixture, various type of oil skimmers are used

in the industries. The intension of this project is to design and conduct an performance study

on belt type oil skimmer. The belt skims the oil from water which can be wiped out, and which

is collected in the tank. The collected oil can be reused for many purposes. In these kinds of

skimmers different types of belts are used.

Performance and efficiency of these systems mainly depends on the type of belt, belt material

and speed of belt play a major role. So it is important to study and analyze the performance of

various types of belts in order to select proper belt for better performance. The outcome of this

project increased our understanding of type of belts, material of belt and speed of belts on rate

of oil collection.

Abstract

Automobile safety is increasing trend as the vehicles are getting more powerful and faster than

before. Still accidents are being taking place. There are several measures taken for the

prevention of accidents by using sensors to seat belts and to air bags as well. Here we stepped

for the safety of passengers and to avoid the car damage loss. Here in our case we will be

having a front and a rare bumper in our system and a twin separator accumulator is situated in

the middle of the vehicle. The front and rear bumper connected to the piston and cylinder

arrangement (two on each bumper) and these piston-cylinder (cushioning effect) connected to

an accumulator (twin separator) by connecting Hoses. A vehicle moving, when collides or hits

to an obstacle, the bumper which is connected to the piston rods with a pivot joint will absorb

the impact force by retracting in the piston cylinder. It contains oil and compresses the oil in

the cylinder which is connected to the accumulator through the connecting pipes. This displace

of fluid results in comes out of rear bumper which prevents the huge damage of car from back

side like in case of pileup in foggy weather and the passengers sitting in the vehicle/car can be

saved.

Abstract

Abrasive Jet Machining (AJM) is the process of material removal from a work piece by the

application of a high-speed stream of abrasive particles suspended in a gas medium from a

nozzle. The material removal process is mainly caused by brittle fracture by impingement and

then by erosion. Being a popular technique among the available nontraditional machining

techniques, AJM uses only one type of abrasive powder in its regular design. In the present

work an attempt is made to make use of two abrasive grit materials together to achieve faster

machining rate with accurate contour forming. Miniature working model was developed based

on the available machine setup as the reference. Experimental results showed the minimum

nozzle wear when a mixed abrasive particle was used to complete the machining process.

Abstract

Agriculture is the backbone of our country. The history of agriculture in India dates back to

Indus Valley Civilization Era and even before that in some parts of southern India. Today, India

ranks second worldwide in farm output. Special vehicle or equipment plays a major role in

various fields such as industrial, medical, military applications etc., The special vehicle or

equipment is gradually helping in increasing the productivity in agricultural field. Present

Agricultural equipments are of high cost. Though India is mainly an agricultural country,

farmers are not equipped with the required tools and machinery for agriculture that modern

time demands. Most of the current agricultural machines perform limited number of operations,

or if they do carry out more operation, it comes at a greater price. Hence, we propose to develop

equipment which is push driven, light, cost efficient and does multiple operations such as

fertilizer spreading, sowing seeds and spraying of water and/or pesticide. Also, we propose to

make it detachable so that it can be used according to requirement and can be moved around

easily.

A fertilizer hopper has been provided at the front end which stores the fertilizer, below which

a spreader disc will spread the fertilizer circumferentially as the equipment moves forward. A

Seed Hopper is provided to store the seeds, inside which a gear meters out the seed through a

shaft. The fertilizer hopper is made detachable so that a pesticide tank can be equipped instead.

It is a simple piston - cylinder pesticide-sprayer which pressurizes the pesticide.

Abstract

Blanking is one of the most commonly used sheet metal manufacturing processes in the

industry. Having a good understanding of the fundamentals and science behind this high

deformation shearing process can help to improve the tool life. The HSS Punch tool is used to

punch the 12mm thickness of sheet metal to make a fine blanking component. Various factors

during the operation like, effect of bur formation, Punch-die clearance and tool tip geometry

causes the tool get failure. The interaction between punch, stripper plate and sheet metal of

12mm thickness is first studied experimentally by using different geometry of Punch tools,

fundamental understanding of the behaviour of the components at different loads at high

speeds. By the experimental results, select the best performed tool and that punch tool material

and it is analysed by conducting material testing by reference of its specification. They are

chemical analysis, hardness test, thermal and micro testing. The stress distribution is

determined by using Ansys simulation for both punch tool and the sheet material. The tool life

of HSS flat punch is calculated theoretically and same is compared with the Ansys simulation

results and determines the safety factor of the tool.

Abstract

Sugarcane is an important cash crop and cultivated between 320N to 320S latitude covering

more than 90 countries of the world. India contributing 19.98% of the total world production

is the second largest producer of sugarcane next to Brazil. In India, it is grown between 700N

to 320N latitude covering large variation in climate, soil-crop spread and productivity. The

major producing states are Uttar Pradesh, Maharashtra, Tamilnadu, Karnataka, and Gujarat.

Use of machinery helps in labour saving and timeliness of operations, reduces drudgery, helps

in improving quality of work, reduces cost of operation and ensures effective utilization of

resources. In India considerable R & D work for design and development of agricultural

implements and machinery for few operations have been developed. However, the adoption of

these implements and machinery have not been up to the desired level. Thus, there is a

considerable mechanization gap, especially in the area of sugarcane planting, intercultural,

plant protection, harvesting and ratoon management. Therefore, it is necessary that

concentrated efforts be made for adoption, development and popularization of sugarcane

machinery for various operations. In this paper different operations of sugarcane cultivation

along with their mechanization are discussed.

Keywords: Machinery, cultivation, sugarcane, harvesting.

Abstract

The increase in demand for refrigeration globally in the field of air-conditioning, food

preservation, medical services, vaccine storages, and for electronic components temperature

control led to the production of more electricity and consequently an increase in the CO2

concentration in the atmosphere which in turn leads to global warming and many climatic

changes. Thermoelectric refrigeration is a new alternative because it can reduce the use of

electricity to produce cooling effect and also meet today’s energy challenges. It uses Peltier

effect to reduce the temperature.

Keywords: Peltier Module, Heat Sink, Peltier-Effect, Refrigerator.

Abstract

Energy is fundamentally the ability to do work. The society come about to be as complex and

modernized as it is due to evolutionary paths taken in energy conversion from one form to

another. The world is however majorly concerned of the utilities to reduce the emission from

electricity generating plants by employing renewable energy and to supply at low cost

electricity to remote areas. Hybrid power systems provide such solutions due to the

employment of renewable energy (RE) that are freely available in nature, readily available and

environmentally friendly reducing greenhouse emissions. The renewable energy sources such

as Wind and Solar are universal and ecological to generate electricity and battery as a back-up

system. The system components and specifications are arrived at after load assessment is done

and the solar insulation and wind speed data are obtained. The micro grid is expected to provide

stable electricity supply to the area throughout the year at minimal cost and be environmentally

friendly. To make solar energy more fruitful, the efficiency of solar array systems must be

maximized. For the efficiency evaluation of PV cells, that has been discussed with particular

attention to the tracking of sun to get maximum intensity of light on the panel surface.

Keywords: Solar energy, Wind energy, Battery, solar tracking, PV cells, Hybrid Power system.

Abstract

This report describes about the wind power and its potential that can be harnessed in the future to meet the current

energy demand. With detailed description of the wind turbine and the wind generator focus has

been given on the interconnection of the generators with the grid and the problems associated

with it. The shape of the blades is changed to helical so that it can rotate continuously at any

direction of wind. Hence the efficiency of the turbine is improved and also the stresses are

minimized. Conclusions were made about the behavior of the wind in urban location.

Thereafter, the helix angle of the blade is changed and the best angle of operation is analysed.

Vertical axis wind turbines (VAWTs) are gradually receiving more and more interest due to

their lower sensitivity to the yawed wind direction. Compared with straight blades VAWT,

blades with a certain helicity show a better aerodynamic performance and less noise emission.

Nowadays computational fluid dynamics technology is frequently applied to VAWTs and

gives results that can reflect real flow phenomena. In this paper, a 2D flow field simulation of

a helical vertical axis wind turbine (HVAWT) with four blades has been carried out by means

of a large eddy simulation (LES). The power output and fluctuation at each azimuthal position

are studied with different tip speed ratio (TSR). The result shows that the variation of angle of

attack (AOA) and blade-wake interaction under different TSR conditions are the two main

reasons for the effects of TSR on power output. Furthermore, in order to understand the

characteristics of the HVAWT along the spanwise direction, the 3D full size flow field has also

been studied by the means of unsteady Reynold Averaged Navier-Stokes (U-RANS) and 3D

effects on the turbine performance can be observed by the spanwise pressure distribution. It

shows that tip vortex near blade tips and second flow in the spanwise direction also play a

major role on the performance of VAWTs.

Abstract

Arecanut is the staple commercial crop of Karnataka having root in 15 districts. But the major

problem the areca agriculturists are facing today is the scarcity of labor. Presently the climbing

and spraying of pesticides to tree is done manually, which requires skilled laborers. This

manual method is a risky job and there have been incidents of accident that has occurred while

climbing the tree; that has led to paralysis and sometimes even death of climbers. There is

scarcity in the availability of skilled laborers. Also, the climbers demand a lot of money, which

is not economical for agriculturists who cultivate the crop in a small-scale level. Thus, an

alternate solution is required to solve the above problems and in this proposed work we propose

an alternate solution. This project solves all the problems regarding the climbing, spraying and

harvesting of arecanut tree, thus developing a safer, reliable and an economical system. Initially

a prototype of the above model was made and was tested. The test was successful and based

on the observations done while testing the prototype, the model is being fabricated.

Keywords: arecanut, sprayer, climber, harvester

Abstract

The main objective of the wheel rim is to provide a stable base to fit the tire. Its physical

parameters such as dimensions, shape and size should adequately fit the tire required for a

particular vehicle. Design plays a major role influencing the quality of the product. In this

project the wheel rim is designed using a 3D modeling software called CATIA v5. The

purpose of modeling is to reduce the time taken and risk factor involved in producing

complex 3D models. Later the part design of wheel rim is imported to an analysis

software called ANSYS. ANSYS is generally used to simulate various physical

parameters like forces, pressure acting on the given components. It is also used in

calculation of stresses, deflections and other parameters without human intervention.

Thereby reducing the time spent on mathematical calculations by a human.

In ANSYS, we are particularly performing static analysis on wheel rim by considering

four different materials namely Aluminium alloy 6061, Magnesium alloy, Steel 1008 and

Carbon Fibre. Their relative performances have been studied and observed. By

comparing the relative results of all the materials in static analysis, we would suggest

Carbon Fibre as the best material for the design of the wheel rim.

Keywords: Wheel rim, Catia v5, Static Analysis, Ansys.

Abstract

The cycle time for conventional manufacturing process of ALCO barrel is very high. This is

due to high non-machining time owing to a greater number of machines involved. An attempt

is made to reduce the cycle time for ALCO barrel and to establish the shoulder turning

operation. The solution is provided in the form of CNC Hard Part Turning Machine which is

capable of accommodating all the machining process in a single machine.

It is found that in CNC machine the shoulder dimension of the machined component is not

within tolerance leading to high rejection rate. After study and analysis, a mandrel with a

locking mechanism is designed to position the barrel accurately with a reference to maintain

the shoulder dimension within tolerance. The end stopper of the CNC machine is also

redesigned for the purpose of accommodation of the mandrel. The results indicated substantial

decrease in the production time of ALCO barrel and also reduction in rejection rate of the

ALCO barrel manufactured in CNC hard part turning machine.

Keywords: ALCO barrel, hard part, shoulder, CNC
