MET351 Computer Aided Manufacturing (CAM)

This course provides the student with experience in computer graphics NC programming techniques. Students will generate 2-D and 3-D parts on CAM software and analyze the tool paths required for various types of machining operations. Programs will be processed to produce EIA-NC code which will then be loaded into a CNC machine to manufacture a part. Students will also create 2-D and 3-D files on CAD software and learn how to export the CAD files to CAM software.

Prerequisite(s): MET 127

Course Learning Outcomes:

  • Students will be able to generate 2D toolpaths and simulations using a computer aided manufacturing software program.
  • Students will be able to generate 3D toolpaths and simulations using a computer aided manufacturing software program.
  • Students will be able to develop machining methods to machine mechanical components.
  • Students will be able to create CNC setup sheets that document required cutting tools and initial machine setup.
