CNC machine programmers develop programs that tell automatic machine tools, equipment, or systems how to work.

Are you someone who likes to set up and operate machines through computers? As a CNC machine programmer, you are responsible for the programming, set-up and operation of vertical milling control (VMC) and other computer-controlled machines. These jobs are usually found in the production of precision sheet metal, machined parts, robotics or plastic, where the factory relies on computers to run small and large scale fabrications. You’ll occupy one of the most important positions on the production floor, working alongside machinists, technicians, and assemblers to create a high-quality finished product.

CNC machine programmer is a job that involves a high level of responsibility and precision. You’ll be in charge of writing programs that direct machine operation. First, you’ll look at engineer-created technical drawings in order to decide the positions, speeds, and tools needed to create a product. Next, you’ll write a program into a machine’s control center using computer-aided manufacturing (CAM) software. This means you’ll need a lot of training and knowledge on the subject of computer programming as well as experience on the production floor in order to write the most precise program possible.

In addition to writing the programs that control the machines, you may need to operate the machines by loading materials or unloading a finished product. This is also important in order to make sure that the program you write is producing the best product possible. If not, you’ll need to know how to make adjustments to the program or machine set-up.

Many CNC machine programmers are promoted from positions on the production floor, but you’ll need additional training in programming language and technical drawings reading in order to become a programmer. A certification or training program is a great way to gain the knowledge and experience you’ll need for the job.
