What does a CNC Programmer do?
Published 4 min read
A CNC programmer is responsible for creating the instructions that tell a computer numerical control (CNC) machine what to do. This can involve anything from creating simple 2D designs to complex 3D models. The programmer must have a strong understanding of engineering and machining principles in order to create programs that will produce the desired results.
CNC Programmer job duties include:
- Read and interpret blueprints, technical drawings, and computer-aided design (CAD) files
- Convert instructions into a code that the machine can understand
- Load programs into the machine and monitor its progress
- Make necessary adjustments to programs as needed
- Perform routine maintenance on the machine
- Keep accurate records of all programs created
- Train other workers on how to use the machine
- Assist in the design of new products
- Investigate new CNC technologies
CNC Programmer Job Requirements
A CNC Programmer is responsible for creating programs that tell computer numerical controlled (CNC) machines what to do. They may also be responsible for maintaining and repairing CNC machines. A CNC Programmer typically needs a high school diploma or equivalent, although some jobs may require postsecondary education, and most jobs require some on-the-job training. Some CNC Programmers may need to be certified by the National Institute for Metalworking Skills (NIMS).

How to become a CNC Programmer
There are many ways to become a CNC Programmer. One way is to attend a trade school that offers CNC programming courses. Many community colleges also offer these courses. Once you have completed a CNC programming course, you will be able to take the certification exam offered by the National Institute for Metalworking Skills (NIMS). After passing the exam, you will be a certified CNC programmer.
Another way to become a CNC Programmer is to find a company that is willing to train you on the job. Many times, these companies are looking for individuals with some experience in machining or engineering. They may require you to complete a training program before they will allow you to operate their CNC machines. Once you have completed the training, you will be able to work as a CNC programmer for that company.
There are also many online resources that can help you learn how to become a CNC Programmer. These online courses can be found at many different websites. Many of these courses are offered by community colleges and trade schools. These courses will teach you the basics of CNC programming and how to use different software programs that are necessary for operating a CNC machine.
Once you have completed a course or two, it is important that you get some hands-on experience with a CNC machine. Many times, companies will allow prospective employees to shadow someone who is already working as a CNC programmer. This will give you the opportunity to see how the job is done and what type of tasks are performed on a daily basis. It is also important that you get some experience programming different types of materials. This way, when you do eventually get a job as a CNC programmer, you will already have some experience working with the types of materials that your new company uses.
