How to Become a CNC Machinist
As manufacturing facilities evolve from dangerous factory floors to automated fabrication centers, computer numerically controlled (CNC) machines are the heart of modern manufacturing.
From lathes and mills that cut raw materials into usable shapes to 3D printers that create useful designs from bulk materials, CNC machines use computer code to transform ideas into objects and products.
CNC machinists take design drawings – often in the form of computer-aided design (CAD) files – and program the machines to build the physical product. They then load, operate and oversee the machine as it completes its assigned operation.
CNC Machinist Career Outlook
Although CNC machines have been in wide use since the 1980s, many experts believe the technology is just now reaching maturity. The integration of CNC with robotics and especially the advent of CNC-based 3D printing hold great promise for advances in automation and specialization in CNC machining.
As the use of CNC machines grows, the underlying technology remains quite stable. Whether they are working with routers, drills, 3D printers, glass cutters or highly specialized machines, CNC machinists are expected to:
- Interpret designs of parts to be machined
- Use technical calculations and models to program a CNC machine
- Choose tools or attachments required for a product order
- Set manufacturing metrics such as tolerance levels or cutting speeds
- Maintain and upgrade CNC machines to optimize productivity
- Validate a machine’s output based on the technical standards for a project
- Operate machines under computer numerical control, including lathes, mills, presses, and drills, 3D printers, glass cutters and more
These are highly technical operations that require mental dexterity and specialized knowledge. They are highly valuable to today’s advanced manufacturers.
As a result, well-trained CNC machinists can expect bright career prospects. In fact, consulting firm Deloitte expects a skills gap among manufacturing professionals who have programming skills and understand advanced machinery. Deloitte estimates that as many as 2 million advanced manufacturing jobs may go unfilled between now and 2025.
According to the US Bureau of Labor Statistics (BLS), machinists earn almost $22 per hour, or $45,750 per year, on average. Including overtime and bonuses, many experienced CNC machinists make between $50,000 and $80,000 per year.
