-- LEO BUSCAGLIA ---

Mechanical engineering is a discipline of engineering thatapplies the principles of physics and materials science foranalysis, design, manufacturing, and maintenance ofmechanical systems. It is the branch of engineering thatinvolves the production and usage of heat and mechanicalpower for the design, production, and operation ofmachines and tools. It is one of the oldest and broadestengineering disciplines.

The engineering field requires an understanding of coreconcepts including mechanics, kinematics,thermodynamics, materials science, and structuralanalysis. Mechanical engineers use these core principlesalong with tools like computer-aided engineering andproduct lifecycle management to design and analyzemanufacturing plants, industrial equipment andmachinery, heating and cooling systems, transportsystems, aircraft, watercraft, robotics, medical devicesand more.

Scope There is tremendous scope for mechanical engineers inautomobile engineering, cement industry, steel, powersector, hydraulics, manufacturing plants, drilling andmining industry, petroleum, aeronautical, biotechnologyand many more. Nowadays they are also increasinglyneeded in the environmental and bio-medical fields.

Mechanical Engineering activities at the GMR Institute of Technology commenced in 1997. The Department is accredited with NBA as well as NAAC. The annual intake of this Department is 120 students.

The Department of Mechanical Engineering offers a richly integrated curriculum of education and research to its students. The Department offers Masters programme (M.Tech. Thermal Engineering). Students have a variety of opportunities to investigate a broad range of research in thrust areas. Some of the specific areas include Alternate Fuels, Nano Materials and Coatings, Metal Matrix Composites, Bio-degradable Polymers and Reliability Engineering. Much of the research is conducted within the department, but many projects are carried out in collaboration with other departments and centers on campus, as well as with other R&D institutions and national laboratories in the country and abroad. The faculty, students and staff author have research publications annually in leading national and international journals and conferences. Several of the faculty are fellow of various national academies in science and engineering, and have received recognition in the form of national and international awards. The alumni and staff of this department occupy high positions in institutions of higher learning, research laboratories and industries in India and abroad

The Mechanical Engineering Faculty is continuing to explore new areas of research and develop new courses. The Department is well equipped with state of the art laboratories and infrastructural facilities. The Department receives funding from agencies such as UGC, AICTE, DST, and public and private industries. Our faculty members render assistance to leading industries through technical advice and consultancy services.

AUTOMATIC FOUR WAY MULTI HACKSAW CUTTING MACHINE

Design of Multi Hacksaw Cutting Machine - Mr. S. Chiranjeeva Rao, A Sai Vamsi and

A Naveen

The main objective is designing an efficient automatic four-way multi hacksaw cutting machine using the principle of slider crank mechanism. The slider in the slider crank mechanism is replaced by hacksaw cutter to get the required model of hacksaw cutter machine. Here, the crank with shaft is rotated which makes the hacksaw cutter to reciprocate in the guideway where the cutting operation is done and feed is given automatically. Here the sizes and fabrication are done by considering kinematic analysis and load capacity of the motor. This machine can be used for industrial applications like cutting thin metal bars, woods and household purposes like cutting PVC pipes and other materials. The advantage of this project is in reducing the human effort and portability of this machine which can be easily moved. The machine works significantly with minimum vibrations and jerks. To achieve mass production in industries the automatic four-way multi hacksaw cutter machine where eight (8) jobs will be done at one time is developed. COMPONENTS: These are the components to be used:

• Hacksaw cutter

• Hacksaw blade

• Electric motor

• Disc

• Base frame

• Connecting rods

• Guide ways

• Pipe Holders

• Coolant

• Electrical connections WORKING PRINCIPLE:

• Four-way multi hacksaw works on slider crank mechanism The rotary motion is converted into reciprocating motion.

• Here the rotary motion of disc attached shaft with an eccentricity will be converted into reciprocating motion of the hacksaw cutter.

ASSEMBLY: Step 1:

Construct the outer frame and here the electric motor is placed vertically and a hollow disc is mounted on it with permanent welding with a washer to give support. Step 2: Now, A shaft will be placed in the circular disc and it will be connected hacksaw cutter with links connected in between. Step 3: Hacksaws are fixed in the guideways and job holders are fixed to get perfect alignment of the pipes.

ADVANTAGES:

• Reduce the work of labor

• High production rate

• Low initial cost and less weight

• Maintenance cost is low and Skilled person is not required

• Simple construction and will work under all atmospheric conditions

• It is able to cut Eight pieces simultaneously without any jerks and vibrations and hence requires less time

LIMITATIONS:

• Special device should be used to cut different materials and for the variation of speed.

• Stress concentration in the threaded portions under variable load conditions in screwed joints will affect the life of the machine.

APPLICATIONS:

• Construction industry

• Mass production

• Engineering industry

• Workshop
