CAD & CAM’S USE IN INDUSTRIESCAD & CAM is concerned with application of
computers to various deptts. Starting from design office to production deptt., To machine shops & assembly shops, to inspection & quality control deptts., Right through to the finished parts store.

COMPUTER AIDED DESIGNS(CAD)CAD can be defined as use of computers to
aid the design process.CAD systems are being used in various
stages of design ,development & manufacturing such as conceptual design, analysis, rapid prototyping, documentation and manufacturing.
CAD methods are being used in design of engineering components, automobiles, aircrafts, buildings, textiles etc.

IMPORTANCE & NECESSITY OF CADAs computers can store & handle large amount
of engg. Data which can be used in various stages of design, process planning, manufacturing, analysis etc.
Complex geometrical shapes can be visually checked & inspected using 3D models.
CAD packages can be employed for design analysis and optimization before actually implementing the design.
It makes design modeling and simulation an easy task.

IMPORTANCE & NECESSITY OF CAD (contd.)
Product design & development cycle can be markedly reduced which in turn reduces lead time.
Design is an interactive process so various alternative designs can be easily compared using CAD & the best one can be implemented.

COMPUTER AIDED MANUFACTURING (CAM)CAM may be defined as any support that can be
provided by computers in manufacturing a given product.
Computers can be used for operation and control of a manufacturing process.(Direct Role)
Computers can be used for process planning, NC part programming, material handling and storage, inspection, inventory control and quality control.

COMPUTER AIDED MANUFACTURING (CAM) Cam uses NC( numerical controlled) machines and
CNC( computer numerical controlled ) machines with the help of NC programs and APT programs.
With the help of these programs we can control the motion of machines such as milling, drilling, cutting etc.
In NC part programming we have to enter a sequence of instructions and machines work accordingly. For Ex.
M00- PROGRAM STOP M06- TOOL CHANGE

COMPUTER AIDED MANUFACTURING (CAM)
In APT we have to give motion statements like GOTO, FROM,POINT etc.
With the help of CAM, machines work as per requirement and thus,
1. Increases accuracy and productivity.2. Reduces cost of production, set up time
and scrap.3. Reduces direct labour and workpiece.4. Make design changes and prototypes
making easy

Industrial robotsEven robots have been designed by using
CAD & CAM methods and controlled by using languages VAL, ROBEX, AML, HELP etc.

AUTOMATION
It deals with application of mechanical, electronic, computer and information technology based systems to operate & control production.
CAD & CAM are parts of AUTOMATION.There are 3 types of AUTOMATION:-1.Fixed Automation2.Programmable Automation3.Flexible Automation Industries select a type of automation according
to its different batches of production.
