COURSE CONTENT

Student Learning Outcomes:
At the conclusion of this course, the student should be able to:

1.  Grind a tool bit utilizing a pedestal grinder and a piece of high speed steel (H.S.S)

2.  Machine a threaded pin utilizing the tool bit that was previously made from H.S.S.

3.  Mill a plate on a milling machine from a blueprint.
