MAC 142A Machining Applications II Lab

Lecture: 0 Lab: 6 Clinic: 0 Credits: 2

This course provides laboratory instruction in the wide variety of processes associated with machining. Topics include safety, equipment setup, holding fixtures, tooling, cutting speeds and depths, metal properties, and proper finishes. Upon completion, students should be able to safely demonstrate advanced machining operations, accurately measure components, and produce accurate components with a proper finish.

Pre-requisite(s): MAC 141 and MAC 141A.
Co-requisite(s): MAC 142.
Course is typically offered in Spring.
