About Program

Computer Numeric Controlled (CNC) machines are widely used in the machining industry. This one-semester program is designed for in-depth study of CNC machines. Students will learn how to set-up and run a CNC lathe, machining centers and grinders. In addition, students will receive training on a Computer Aided Design (CAD) system.

Note:  To enroll in the CNC program, prospective students must have completed Machine Tool program or have five-years of verifiable work experience in a Machine Shop and pass a competency test.  Students will need to contact the instructors to schedule an interview for acceptance into the class. 

Job Expectations

CNC Machinist opportunities are available in several job settings such as a machinist in manufacturing plant, in a job-shop or in a maintenance machining position.

Expected Earnings

A machinist with little to no experience will make $15-$18 per hour.  After three years, the hourly wage increases to $18-$20 and, when one reaches the journeyman’s level, the rate could be $22 or higher.

Course Schedule

Students may enroll during the fall, spring or summer term provided space is available.  Students who are eligible to enroll will be given an opportunity to register for one of the open seats during the enrollment period for each term.
