MAC 124 CNC Milling

Lecture: 1 Lab: 3 Clinic: 0 Credits: 2

This course introduces the manual programming, setup, and operation of CNC machining centers. Topics include programming formats, control functions, program editing, part production, and inspection. Upon completion, students should be able to manufacture simple parts using CNC machining centers.

Pre-requisite(s): MAC 121, MAC 141, and MAC 141A.
Course is typically offered in Spring.
Student Learning Outcomes (SLOs)
At the completion of the course, the students should be able to do the following:

Write a two blocks of Computer Numerical Control (CNC) code to load a tool and the appropriate tool length offset.
Write a block of Computer Numerical Control (CNC) code to turn the spindle on clockwise and set the given RPM.
Write a block of Computer Numerical Control (CNC) code to rapid traverse to a given coordinate.
Create a Computer Numerical Control (CNC) program to develop a tool path using linear interpolation and CW and CCW interpolation in the “X” and “Y” axis.
Create a Computer Numerical Control (CNC) program that incorporates canned cycles for drilling and tapping.
Create a Computer Numerical Control (CNC) program that incorporates canned cycles for Counter bores, Countersinks, and Spotfaces.
Demonstrate a Power-up restart using a CNC Milling Center.
Reproduce a CNC program using a floppy disk or flash drive using a CNC Milling Center.
Debug a CNC program using a CNC Milling Center and run a graph of the tool path.
