What does a CNC Machinist do?
Published 4 min read
A CNC machinist is a professional who uses computer numerical control (CNC) machines to create parts and products. CNC machinists must have a strong understanding of mathematics and computer science, as well as engineering and manufacturing principles. They use this knowledge to program CNC machines, which are then used to create parts for a variety of industries, including automotive, aerospace, and medical.
CNC Machinist job duties include:
- Read and interpret blueprints, engineering drawings, and sketches to determine the best machining methods.
- Plan the sequence of necessary operations to perform on the workpiece, and decide which tools to use.
- Select the appropriate cutting tools for each operation, and load them into the CNC machine.
- Set up and operate CNC machines to perform the planned sequences of operations.
- Monitor the progress of each job to ensure that it is being completed according to specifications.
- Make adjustments to the machine as necessary to ensure proper cutting and tolerances.
- Perform regular maintenance on CNC machines to keep them in good working condition.
- Keep accurate records of all production jobs, including details of any problems that occurred.
- Report any problems with machines or production processes to a supervisor.
CNC Machinist Job Requirements
A CNC Machinist typically needs a high school diploma or equivalent, although some jobs may require postsecondary education, and most machinists receive on-the-job training. Many community colleges offer certificate or associate degree programs in CNC machining. Some employers may require certification from professional organizations, such as the National Institute for Metalworking Skills or the American Machinist Association. CNC Machinists need several years of experience working with computer numerical control equipment and machining tools before they can become fully proficient.

How to become a CNC Machinist
A CNC Machinist is a professional who uses computer numerical controlled (CNC) machinery to create products. CNC Machinists must be skilled in both the operation of CNC machinery and the programming of these machines. Many CNC Machinists have completed formal training programs at technical colleges, but it is also possible to learn on the job.
The first step to becoming a CNC Machinist is to complete a formal training program at a technical college. Many community colleges offer programs that can be completed in two years or less. During your training, you will learn how to operate CNC machinery and write programs for these machines. You will also learn about safety procedures and quality control standards.
After completing your training, you will need to find a job with a company that uses CNC machinery. It is important to get experience working with different types of CNC machines. You should also try to get experience programming these machines. Many companies are willing to train new employees on the use of their specific machines.
Once you have gained some experience, you may want to become certified as a CNC Machinist. Certification shows potential employers that you have the skills and knowledge necessary to perform the job safely and correctly. Certification is not required, but it may give you an advantage when applying for jobs.
