Computer Numerical Control

Computer Numerical Control (CNC) is a computer-aided machine tool system that creates parts and structures to very precise tolerances. It is a staple of modern manufacturing. This program teaches students the technology behind the CNC process, so that they can apply their new skills in a modern machine shop using the latest CNC/CAM software. Students will practice with industrial size 3, 4 and 5-axis vertical and horizontal milling machines, and with a 3-axis tooling turning center with conversational control. Students also learn information literacy, hazardous material processes, and manufacturing trends.

Students interested in Computer Numerical Control (CNC) should enroll in Machining Technologies. For more information, visit the Machining Technologies program page.
