What Is a CNC Machinist?

If you're considering a career working with precision tooling in a machine shop, read on. Learn about the job duties and training requirements for computer numerically controlled (CNC) machinists. Schools offering Machining & Manufacturing degrees can also be found in these popular choices.

CNC Machining Defined

Many parts, such as those found in cars, household appliances, computer hardware or other pieces of machinery, can be described as a mathematical series of lines and curves. CNC machining is the process of mapping out these parts' specifications on a computer software program and turning them into operating instructions for a lathe, mill or press. This process ensures that a part is produced with the same precision, every time.

Tasks and Job Duties

As a CNC machinist, you are responsible for setting up a machine to make the proper sequence of cuts. This could entail writing programming instructions or making adjustments to a program should you discover problems during a test run. You may also replace worn out parts and monitor the production process.

Education and Training Options

You will generally need to receive some formal education at a trade school or community college before beginning work as a CNC machinist. Available certificate, diploma and associate degree programs include introductory courses in machine shop fundamentals, measurement techniques, math, blueprint reading, statistical process control, mechanical drawing and CNC operations. Advanced course topics focus on different types of CNC programming for lathes, mills and grinders.

You might also receive on-the-job training through a trade school or community college's apprenticeship program. Students in these 4-year programs usually attend classes while maintaining full-time employment with a machine shop or manufacturing company. Some locally based professional organizations may also offer apprenticeship programs.

Job Outlook

Employment opportunities for all machinists were expected to grow nine percent over the 2014-2024 decade, according to the U.S. Bureau of Labor Statistics (www.bls.gov). Your job prospects may improve if you know how to operate more than one machine type. As of May 2014, most professionals in this field worked in the machine shop, metalworking machinery manufacturing and employment services industries.
