MACH 241 CNC Machining I: CAD/CAM Geometry and Toolpaths

7 credits
Students will learn to create geometry and toolpaths utilizing CAD/CAM software. The will utilize the Computer Aided Design (CAD) part of the software to develop geometry for manufacturing, such as wireframe and solid models. Students will utilize the Computer Aided Manufacturing  (CAM) part of the software to create 2.5D toolpaths used in CNC machining to produce the geometry and models developed in CAD.

Prerequisites: Completion fo the Machine Technology program or instructor permission.

Quarters Offered: All
