CAD 120 - Introduction to CAM

Credits: 3
Instructional Contact Hours: 4

Introduces the basics in computer geometry creation including line, arc, curve creation and manipulation. Gives a foundation to build on advanced CAD/CAM techniques. Instructs students on file transfer systems from CAD to CAM with emphasis on proper drawing techniques, including file type-save-transfer. Projects will be drawn, checked and created on appropriate equipment. Shows links between CNC machines on the shop floor and their relationship with the design process. Generates code from created drawings to be run on Computer Numerical Controlled equipment. Credit may be earned in CAD 120 or SKCA 120 but not in both.
