CNC with Machining Applications

SKCN 216

Course Description

Prerequisites: Prerequisites: CAD 120 or SKCA 120, MS 181 or SKTR 181, CNC 162 or SKCN 162, MS 182 or SKTR 182.

Emphasizes the programming methodology for producing quality parts using the CNC machines. Discusses conversational programming language with secondary emphasis on tooling setups, part setups, and machining. Utilizes horizontal and vertical machining center for program testing. Credit may be earned in SKCN 216 or CNC 216 but not both. (0-60)
