Licensing & Certification

CNC machinists do not typically need a state license, but industry certifications can significantly boost employability and wages. The National Institute for Metalworking Skills (NIMS) offers credentials in CNC Milling, CNC Turning, and CNC Programming that are widely recognized by manufacturers across the country. Machinists can also pursue NIMS certifications in Measurement, Materials, and Safety or in specific areas like multi-axis machining.

The NCCER (National Center for Construction Education and Research) also offers machining certifications. Some employers may require or prefer candidates with specific NIMS credentials, especially for higher-level positions or work in regulated industries like aerospace and medical device manufacturing where documentation of skill competency is required.

Career Outlook & Salary

The Bureau of Labor Statistics reports a median annual wage of $56,150 for machinists as of May 2024, which works out to approximately $27.00 per hour (BLS, OEWS, May 2024). Experienced machinists working in aerospace, defense, or medical device manufacturing can earn well above the median, particularly those with multi-axis programming skills or specialized material expertise. Entry-level operators typically start below the median and see meaningful wage increases within the first 2 to 3 years as they develop proficiency.

Overall employment for machinists is projected to show little or no change through 2034, but the BLS still projects approximately 29,500 annual openings – driven largely by the need to replace workers who retire or transfer to other occupations. The large volume of replacement openings means that well-trained CNC machinists should continue to find employment opportunities, particularly in regions with strong manufacturing sectors like the Midwest, Southeast, and parts of the Northeast. Reshoring of manufacturing capacity and growth in defense spending are additional factors supporting demand.

Where You’ll Work

CNC machinists work in climate-controlled or semi-controlled machine shops and manufacturing facilities. Typical employers include aerospace and defense contractors, automotive parts manufacturers, medical device companies, oil and gas equipment fabricators, electronics manufacturers, and general-purpose job shops that produce custom parts for a wide variety of clients. Work schedules often include shift work, as many manufacturing operations run second and third shifts to maximize equipment utilization.

The job is indoor and stationary compared to many trades, though it requires standing for long periods, loading heavy materials, and working in close proximity to cutting tools, metal chips, and coolant. Machine shops range from small operations with a handful of machines to large production floors with dozens of CNC centers running around the clock.

Online vs In-Person Options

CNC machining requires significant hands-on training with actual machines. Operating a CNC mill or lathe, setting up tooling, loading workpieces, and performing precision measurements must be done in person in a properly equipped machine shop. There is no online substitute for learning how cutting tools interact with different materials, hearing the sound of a proper versus improper cut, or developing the tactile skills that experienced machinists rely on.

Some programs offer online or hybrid delivery for supporting coursework like blueprint reading, shop math, GD&T, or introductory CAD/CAM software training. This can reduce time on campus for students who need scheduling flexibility. When choosing a program, look for schools with modern CNC machines (not just manual equipment), adequate shop time per student, and curriculum that includes both operation and programming.
