IMPORTANCE & NECESSITY OF CAD
As 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.
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.
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:-
Fixed Automation
Programmable Automation
Flexible Automation
Industries select a type of automation according to its different batches of production.
