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

6 credits

Students will learn to create geometry and toolpaths utilizing CAD/CAM software. They 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: MACH 143 , MACH 145 , MACH 162 , AND MACH 175

Corequisites: MACH 196
