Upon completion of this course, the student will be able to:
1. Practice the safe use of tools and machines.
2. Compare and contrast manual and CNC (computer numerical control) mill
3. Relate the theory of CNC mill operation to machining processes.
4. Generate two-dimensional geometric images for CNC mill projects using
computer-aided drafting (CAD) software.
5. Using a drafted image, write and interpret code for machining a part on
a CNC mill.
6. Troubleshoot code for incorrectly machined parts.
7. Calculate cutting speeds and feed speeds for various computer numerical
control mill operations.
8. Select appropriate tool bits for machining to CAD specifications.
9. Diagnose basic problems faced in the operation of the computer numeric
10. Students who repeat the course will accomplish mill machining
processes utilizing the Master CAM (computer-aided machining) program,
a more advanced and powerful computer-aided drafting and machining
software that utilizes a post-processor to process code for machining.
