A CNC operator sets up, monitors, and maintains computer-controlled machining systems that produce precision components.
The CNC operator career path offers progressive roles in production, programming, and engineering—spanning multiple industries and technologies.
What Does a CNC Operator Do?
A CNC operator runs machines that follow pre-programmed G-code instructions to cut, drill, or mill parts.
They inspect parts, adjust tool offsets, load raw materials, and ensure safe machine operation.
Key responsibilities:
-
Reading technical blueprints and work orders
-
Operating CNC lathes, mills, or routers
-
Performing in-process quality checks
-
Changing tools and maintaining equipment
-
Reporting and troubleshooting machine errors
What Are the Entry-Level Requirements?
Most CNC operators start with a high school diploma and receive on-the-job training or technical certification.
Minimum requirements:
-
Mechanical aptitude and math skills
-
Knowledge of machine shop safety
-
Familiarity with measurement tools (calipers, micrometers)
-
Basic understanding of CAD/CAM is a plus
Recommended education:
Technical diplomas or certificates in CNC operation, machining, or manufacturing technology
