CNC OPERATORS/ PROGRAMMERS
Have you ever wondered where the parts come from to create new machines or to repair or upgrade existing machines? That’s the role of CNC operators and programmers, specially trained individuals who design precision parts, then program and operate computer-driven machinery to make those parts, which are used in all kinds of industries and to help bring new manufacturing technology to life.
WHAT DOES A CNC PROGRAMMER OR OPERATOR DO? CNC stands for computer numerical control, and it refers to a category of machines that are used to precision-produce metal and plastic parts. A CNC operator is a specially trained technician who sets up and operates these machines to cut, shape and form metal and plastic materials or pieces. A CNC operator’s job also includes studying blueprints or other instructions to determine equipment setup requirements. CNC operators conduct test runs of production equipment and make adjustments as necessary. CNC machines work from special designs produced by computer-aided manufacturing (CAM) or computeraided design (CAD) systems. For this reason, CNC operators are sometimes cross-trained on CAD/CAM systems. CNC programmers create the instructions for the computer to tell the machine what to do during the production process. In some cases, one employee performs both jobs. WHAT’S NEW? Computer-controlled equipment represents a quantum leap forward in the industry, as these machines are able to cut, mill or shape parts much faster and with far more accuracy than parts that are created by hand. The technology works in much the same way as the software that powers 3D printers in a lab. CNC technology is a relatively recent invention and continues to evolve at a rapid pace. Machines can form and shape a part from multiple angles at once. Some have the ability to flip the component over during the machining process. CNC machines perform fully automated cuts or drill multiple holes with tremendous precision. WHERE DO CNC OPERATORS WORK? Most CNC operators today work in jobs in manufacturing facilities producing fabricated metal products, plastics and rubber products, transportation equipment, primary metal and machinery.

CNC is a cornerstone technology of advanced manufacturing, which is a much cleaner and safer form of manufacturing and provides a much more comfortable workspace. Employees of companies that use advanced manufacturing generally work in an indoor, climate-controlled workplace. However, CNC operators must observe basic safety rules that may include wearing protective equipment. This equipment may include such things as safety glasses, earplugs and steel-toed boots. You may also have to wear a respirator to guard against fumes or dust, particularly when working with plastics. WHAT’S THE JOB OUTLOOK? According to the U.S. Department of Labor, there were only 100 CNC operators in the state in 2016, which leaves a lot of room for growth. CNC operators are the latest generation of a long line of machine operators and setters that have evolved with changes in technology in manufacturing. As more companies adopt systems that are considered “lean manufacturing,” CNC technology will continue to be an important part of production, and the demand for skilled CNC operators is likely to remain strong. Experts predict the number of these jobs to grow 20% by 2026. Most metal and plastic machine workers are employed full time. Overtime is common, and because many manufacturers run their machinery for extended periods, evening and weekend work is also common. HOW MUCH CAN I MAKE? CNC Programmers • Lower range wages (bottom 10 percent) — $31,340 annually/$15.07 per hour • Middle range wages (median) — $56,360 annually/$27.10 per hour • Higher range wages (top 10 percent) — $109,800 annually/$52.79 per hour
• CNC Operators • Lower range wages (bottom 10 percent) — $27,160 annually/$13.06 per hour • Middle range wages (median) — $37,730 annually/$18.14 per hour • Higher range wages (top 10 percent) — $53,400 annually/$25.67 per hour With experience and expertise, workers can become candidates for more advanced positions, which usually include higher pay and more responsibilities. Experienced workers with good communication and analytical skills may move into supervisory positions. WHAT DOES IT TAKE TO BE SUCCESSFUL? • Computer skills • Mathematics • Physical stamina/strength • Design • Mechanical skills HOW DO I LEARN THE CRAFT? Machine operator trainees usually begin by watching and helping experienced workers on the job. Eventually, these workers develop the skills and experience to set up machines and perform a full range of tasks. CNC machine tool programmers typically need to complete courses beyond high school. CNC operators generally do not complete an apprenticeship like other trades. Some operators are trained on basic machine operations and functions in a few months, while computer-controlled machine tool operators may need up to a year to become fully trained in their craft. Community colleges and other schools offer courses and certificate programs in operating metal and plastics machines that involve CNC programming.
