What Does a CNC Machine Operator Do?

Computer Numerical Control (CNC) technology has changed manufacturing as we know it. CNC machines have enabled manufacturers to create materials faster and more efficiently than ever, allowing for less waste, greater precision, and more customization during the manufacturing process. Due to their benefits, CNC machines are in high-demand—along with CNC machine operators to support the process. CNC operators are skilled technicians who specialize in computer numerical controlled equipment and software. They are essential players in the modern manufacturing industry.

CNC operators, also referred to as CNC machinists, enjoy a mix of hands-on and technological tasks. They typically have good eye for detail, strong understanding of math, passion for technology, and the mechanical skills needed to work with cutting-edge machinery. Still you may be wondering, “What does a CNC operator do on a daily basis?” If you are considering a career in CNC, you may be wondering about the responsibilities and expectations of this role.

What is a CNC Operator?

To understand the work of a CNC operator, it’s important to understand what it means to work with CNC machines. CNC machines are pre-programmed equipment used to create materials and products. They take raw materials (such as metal) and create products based on pre-programmed specifications. CNC machines can be lathes and milling machines, precision cutters, 3D printers, and other technologies that are in high-demand and use by manufacturers today.

CNC operators are the specialists who work directly with this technology. CNC operators will set up, operate, and maintain a variety of different CNC machines, such as the ones listed above. Their main role is to track the manufacturing of a product, through each phase of its creation in the CNC machining process. This might involve loading the program and stock materials, testing the machines, running the production process, and inspecting finished products. However, the CNC operator job description can vary depending on the employer, as well as the exact job title. Other, related titles you may come across include CNC Setup Operator, CNC Maintenance Technician, CNC Machine Programmer, and more.

What Does a CNC Machine Operator Do?

A CNC operator is directly involved in the programming, set-up, and operation of CNC machines. On a daily basis, most CNC machine operators can be found doing the following tasks:

  • Study blueprints, materials, and production plans prior to machining
  • Translate blueprints and drawings into dimensions for production
  • Load and unload raw materials into the machines
  • Set up the machines using proper calibration techniques
  • Program or enter instructions into each machine
  • Complete test runs prior to production
  • Supervise CNC machines as they run, making adjustments if needed
  • Ensure the machines operate in accordance with company and safety guidelines
  • Ensure all safety and company protocols are met during the manufacturing process
  • Participate in safety and training classes for the company
  • Perform inspections of the work area and machinery, before and after production
  • Conduct light maintenance on CNC equipment, such as cleaning tools
  • Inspect finished product to ensure it meets exact specifications
  • Record CNC machine actions throughout process; keep logs of production and quality
  • Communicate logistics issues that arise during the process

If you are new to CNC machining, this list of job duties can be a bit overwhelming. However, you will never jump into a CNC operator career without proper training and preparation. The daily duties of a CNC machinist are highly technical, requiring precision, skill, and foundational knowledge in the field of Computer Numerical Control. You can develop this through a CNC machining training program.

While CNC training may be offered on-the-job for entry-level positions, most manufacturers today will seek candidates who have experience and education already under their belts. For example, at Goodwin University, our CNC training programs are entirely designed around the skills that employers are seeking in graduates. The CNC machining skills and knowledge base that you can develop include:

  • Technical writing and comprehension
  • Manufacturing mathematics
  • Manufacturing materials and processes
  • Understanding of blueprints and technical drawings
  • Job planning and bench layout
  • Hands-on operation of high-tech lathes, milling and turning machines
  • Mastercam, CAD, and CAM software experience

CNC machinists and operators benefit from a job that revolves around innovation and technology. They are on the forefront of manufacturing, helping to oversee more efficient and automated manufacturing processes. If you are looking for a cutting-edge field to break into, CNC machining and programming may be the right fit. You simply need a little training to check off the qualifications needed for the job.

CNC machinist training can be completed in a matter of months, through a CNC certificate program. You can also advance your skill sets through an associate degree program in CNC, if you desire to keep learning and growing in your field. In Connecticut, there are a multitude of CNC machining programs available at Goodwin University.
