CNC 225

Course Description

Prerequisites: Prerequisites: CAD 120 or SKCA 120, and CNC 162 or SKCN 162 or instructor permission.

Teaches the advanced concepts of CNC programming for lathe work, mill 3 and 4 axis work, and/or other machinery, shop floor programming, and the principles of CNC operations. Emphasizes various machining operations, accompanied by demonstrations, student programming, and hands-on setup and machine operation. Emphasizes the creation of error free part programs using the MASTERCAM programming language, including part geometry, tool path, and debugging with secondary emphasis on the downloading of a program to the turning center, mill, machining center/system, or wire EDM. Credit may be earned in either SKCN 225 or CNC 225 but not in both. (15-45)

Outcomes and Objectives

Write a program using the off-line software.

Objectives:

  • Learn software format using the software vendor's programming manual
  • Enter a program into the computer using the software vendor's programming manual as a guide
  • Identify file extensions
