17/25

CAD/CAM

Computer-aided design (CAD) is theuse of computer systems to assist in

the creation, modification, analysis, oroptimization of a design.

Computer-aided manufacturing (CAM)is the use of computer systems to plan,manage, and control the operations ofa manufacturing plant through direct orindirect computer interface with plants

resources. 17


18/25

Need for CAD/CAM

To increase productivity of the designer

To improve quality of the design

To improve communications To create a manufacturing database

To create and test toolpaths and optimize them

To help in production scheduling and MRP models To have effective shop floor control

Magnify an image to see pixels


21/25

Resolution

Number of PIXELS per square inch

Monitors display 72 pixels/sq inch

Printers are much higher 300 pixels/sq inch

File size differences in 1X1 in

Web 5,184 pixels Print 90,000 pixels

Color

Monitors display light directly

Term RGB (Red Green Blue)

Different monitors may display colorsdifferently

Printing images

Term CMYK (Cyan, Magenta, Yellow,

blacK)

Colors will look different than on the screen
