CNC Program

Computer Numerical Control, or CNC, is the process for machining products that uses a computer program to direct a lathe or mill so that the tool can cut the workpiece into a final shape. Even though the automation is sophisticated, the skills of the operator are critical, allowing those with this skill set to be in demand and well paid.  

Many Upstate manufacturing employers seek to fill openings for those with Computer Numerical Control skills. The CNC options at Greenville Technical College, part of the Machine Tool Technology program, offer the training you need to get qualified.
