MTTC 208 - CNC Mill Programming
PREREQUISITES/COREQUISITE: MTTC 107 OR Program Chair Approval
PROGRAM: Machine Tool Technology
CREDIT HOURS MIN: 3
LECTURE HOURS MIN: 2
LAB HOURS MIN: 2
DATE OF LAST REVISION: Fall 2025
Introduces three axis CNC milling machine programming. Develops the theory of programming in the classroom with applications of the program accomplished on industry-type machines. Studies terminology of coordinates, cutter paths, angle cutting, and linear and circular interpolation.
MAJOR COURSE LEARNING OBJECTIVES: Upon successful completion of this course the student will be expected to:
- Consistently demonstrate proper programming format and techniques for manual CNC programming, to machine parts without error.
- Choose appropriate tooling for specified material and machining operation.
- Calculate proper feeds and speeds for optimal tool life, machining time, and part finish.
- Analyze G and M code programs using machine graphics display, verification software, or CAD-CAM verification.
- Complete appropriate documentation for safety, set-up, and quality control purposes.
- Create process plans and routings for multiple machining operations.
- Properly and safely set-up and operate CNC milling machines.
- Use manual, manual data input, and automatic operation modes.
- Troubleshoot program and machining problems.
