CAD/CAM. High-Technology Training Module.

This high technology training module is an advanced course on computer-assisted design/computer-assisted manufacturing (CAD/CAM) for grades 11 and 12. This unit, to be used with students in advanced drafting courses, introduces the concept of CAD/CAM. The content outline includes the following seven sections: (1) CAD/CAM software; (2) computer numerical control (CNC) programming--control of machines by numbers, and advantages/disadvantages of CNC; (3) methods of programming; (4) the axis system--Cartesian coordinates, polar coordinates, and right-hand rule; (5) CAM software (post-processing)--advantages and applying software; (6) CNC machine operation--machine components, safety, selecting cutter tools, tools and fixtures, and controller operation; and (7) machine setup--entering offsets and program testing. A methodology section lists the following resource aids: three references, two videotapes, transparencies, demonstrations, worksheets, hardware and software, jig and fixtures, and unit evaluation. Unit evaluation consists of CNC pretest, two CNC worksheets, three assignments, and a posttest. Fourteen additional transparencies are provided. (NLA)
