Full competence as a CNC machinist, including the capability to program and set up complex parts or jobs, typically requires more training and experience. A machinist could eventually reach this level of competence in two to five years, particularly if they are completing a formal education and certification, while gaining practical experience as they learn. This amount of time is important so that machinists can gain the technical and problem-solving skills necessary for advanced manufacturing jobs.
What Makes a CNC Machinist Different from a CNC Operator?
Some organizations interchange the terms CNC machinist and CNC operator, where the CNC operator has all the aspects of a CNC machinist built into their duties. In many organizations, the CNC operator position is generally considered entry-level in virtually all manufacturing. The operator stocks materials and runs parts, and follows instructions to ensure the final product meets the specifications. The operator sets up and operates CNC machines, unloads raw materials, performs preparatory work to prepare the machine for further testing, and inspects and measures final products. Ultimately, operators do the prep and post-work, while machinists do the actual machining.
A machinist has a slightly higher-level role. Machinists will use various machines and methods to measure and machine parts to blueprints accurately. They gain expertise and enhance CNC machining skills through trade school programs or hands-on experience in the field. As a result, they can machine some complex parts and perform several machining processes.
It is common for machinists to begin as operators and transition to the position of machinist. The CNC industry is very complicated, so machinists often learn the basics of operating a machine before being ready to engage in technical duties.
