Course Description

An intermediate course in manufacturing with vertical machining centers using MasterCAM to develop programs for the purpose of creating metal parts. Basic 2-D toolpaths as well as advanced 3-D toolpath techniques will be discussed and created. Transfer Credit: CSU.

Course Level Student Learning Outcome(s)

  1. Draw accurate 2-D and 3-D parts from a blueprint.
  2. Demonstrate the effective use of MasterCAM's advanced surface toolpaths.
  3. Produce an accurate part within given time constraints for profitability.

Course Objectives

  • 1. Draw an accurate part model given a simple Blueprint.
  • 2. Apply correct toolpaths to drive milling cutters.
  • 3. Select appropriate tools to machine simple 2D parts.
  • 4. Select appropriate tools to machine advanced 3D parts.
  • 5. Verify cutter paths from MasterCAMs advanced machine verification.
  • 6. Understand the effect of correct feeds and speeds relating to the machining of aluminum.
