CNC Precision Machining

CNC (Computer Numerical Controlled) Precision Machining is a growing field requiring specific skills in working with metal. Precision machining creates very precise parts from various metals usually that will need to fit into other larger machines or products. This skill involves accuracy, measurements and math, some programming, ability to read schematics and understand what part is being created.

The CNC Precision Machining Apprenticeship is a three-year program in which students attend courses in the Fall and Spring semesters. The rest of the year the apprentice receives CNC machine training from a dedicated mentor at the hiring company.

Machinists completing this program will have earned an AAS degree in CNC Precision Machining, three NIMS credentials, a certification from the Department of Labor that they are fully qualified for their occupation, and three years of experience.
