Computer Numerical Control (CNC) machining is a vast, extensive field within the ever-evolving manufacturing industry. Becoming a CNC machinist can offer heaps of growth opportunities for your career, with around 35,400 job openings for machinists projected each year. However, before starting your journey, it’s essential to understand the potential work environments you might find yourself in.

Whether you are drawn to traditional machining or cutting-edge technologies, CNC machining has something for everyone.

What is a CNC machinist?

A Computer Numerical Control (CNC) machinist maintains and operates specialized equipment to produce various metal parts, products, and instruments. Vital to modern manufacturing, these computerized machines help to create things we use every day, yet another cog in the wheel that makes the world go round.

To become a CNC machinist, you’ll need a high school diploma and some training, either on the job or at the postsecondary level. Many individuals choose to complete apprenticeships or enroll in certificate programs at career-focused colleges. After training, students must pass the National Institute for Metalworking Skills (NIMS) certification to demonstrate competency in the field.

To be considered a skilled machinist, you must develop technical proficiency in reading blueprints, understanding machine programming, and troubleshooting mechanical issues. Strong mathematical and problem-solving skills are also crucial for making sure that parts meet specific standards. Beyond this, as automation continues to transform manufacturing, CNC machinists should perfect skills and knowledge in robotics and computer-aided design (CAD) software.

Where can CNC machinists work?

As a CNC machinist, you’ll have the chance to work in various exciting and cutting-edge job environments. While work in traditional manufacturing settings is most common, you may find yourself in other industries such as medical device production and automotive manufacturing.

CNC machinists’ work environment

When asking yourself, “Where do machinists work?”, you’ll have to broaden your idea of what they do, as you’ll find CNC machinists nearly everywhere, working in settings with plenty of industrial movement and activity. For example, according to the U.S. Bureau of Labor Statistics (BLS), machinists can often be found in:

• Metal product manufacturing
• Machinery manufacturing
• Transportation equipment manufacturing
• Wholesale trade
• Employment services

Common industries and workplaces in which CNC machinists operate include:

• Machine shops
• Metalworking shops
