IE 4773 - Computer Aided Manufacturing/CNC Machining/Rapid Prototyping

2 lecture hours 2 lab hours 3 credits
Course Description
This course teaches students the fundamentals of computer aided manufacturing (CAM), computer numerical control (CNC) machining, and rapid prototyping (RP). Students will learn how to program a CNC machine using manual G/M code programming and computer aided manufacturing software. The course also provides an overview of rapid prototyping (freeform fabrication) technologies, and students will compare part production via RP and CNC. (prereq: IE 426  or ME 323  or consent of instructor, AE 1311  or ME 1601 )
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
  • Distinguish important capabilities and limitations of CNC machining and RP processes
  • Manually write a CNC program for a CNC mill and a CNC lathe
  • Use CAD/CAM software to create and execute CNC programs to machine workpieces on a CNC mill (for student-generated designs: 2.5D milling, hole-making, and 3D contour milling)
  • Explain workholding concepts and their importance to CNC machining operations
  • Select cutting tools and cutting conditions for various types of machining operations (drilling, facing, pocketing, etc.)
  • Set up a CNC machining center, with oversight from a lab technician

Prerequisites by Topic
  • Knowledge of machining processes (milling, drilling, turning, etc.). Must know how to create a part design using 3-dimensional CAD software

Course Topics
  • Review of machining processes (1 week)
  • CNC machining and programming for mills (2 weeks)
  • CAM software and project work (4 weeks)
  • Workholding (0.5 weeks)
  • Rapid prototyping (1 week)
  • CNC machining and programming for lathes (0.5 weeks)
  • Canned programs and quick code (0.5 weeks)
  • Multi-axis machining (0.5 weeks)

Laboratory Topics
  • The 2-hour weekly lab, plus some additional lecture class periods are used for working with the CAM software package to create CNC programs. The programs are thoroughly simulated and tested before running them on a Haas VF-1 machining center. Students also learn how to set up and operate the Haas.
