The following job responsibilities are common for individuals in CNC machine operator roles:

• Input product specifications into CNC machines
• Adjust speed settings and controls to ensure quality of produced products
• Monitor CNC machines during part and product fabrication
• Test and inspect produced products to ensure products meet specifications
• Adhere to strict safety regulations to ensure safe operation of heavy machinery

A Day in the Life

On the job, a CNC machine operator is responsible for using computer numerical control (CNC) devices to produce tools, parts, and other products. CNC machinery is highly versatile, and operators are able to create complex shapes out of materials such as plastic and metal. While the machines are extremely useful, only a skilled operator will be able to use their knowledge to make sure the shaping of the product is completed efficiently and effectively.

To optimize production, a CNC machine operator must make a number of adjustments based on what is being produced. Factors such as the type of material being used, speed settings, and other controls can affect the overall production quality, but an experienced CNC machine operator will identify the right settings to maintain peak performance. The CNC machine operators will make random checks to ensure that quality is not compromised.

Most CNC machine operators work at a production facility for a corporate or large-scale producer and are capable of using a selection of machines at every stage of the process, from schematic creation to fabrication to end product quality assurance. Automation may be reducing the overall number of CNC machine operation jobs available in the United States, but there is certainly still a market for talented operators and their unique abilities.

Typical Work Schedule

CNC machine operators generally work full-time schedules, but shift work is often required. While some CNC machine operators may perform their roles during normal business hours, those that work in heavy production facilities that produce products 24/7 may be required to work second, third, or weekend shifts.

Typical Employers

CNC machine operators typically work in manufacturing across a variety of industries, including tool manufacturers, auto parts manufacturers, and machine shops.
