MAC 143A Machining Applications III Lab

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

This course provides laboratory instruction in the field of advanced machining. Emphasis is placed on creating complex components, close-tolerance machining, precise measurement, and proper equipment usage. Upon completion, students should be able to demonstrate the ability to produce an accurately machined component with a quality finish using the proper machining process.

Pre-requisite(s): MAC 141, MAC 141A, MAC 142 and MAC 142A.
Course is typically offered in Summer.
Student Learning Outcomes (SLOs)
At the completion of the courses, students should be able to do the following:

Determine the grit, hardness, and composition of grinding wheels from identification numbers without error.
Pass a Grinding Safety test with a score of 88% or greater.
Locate Cartesian Coordinates milling the “X” and “Z” axis using Digital Readout (DRO) to a tolerance of +/-.001” and rough mill grinding parts .005” oversize to a tolerance of +/-.002”.
Demonstrate heat treating skills on A2 tool steel to a tolerance of +/-4 on the Rockwell Hardness scale.
Perform grinding operations perpendicular to a tolerance of +/-.0005” or .004mm.
Perform grinding operations parallel to a tolerance of +/-.0005” or .004mm.
Perform grinding operations flat to a tolerance of +/-.0002” or .002mm.
