Computer Numerically Controlled Tool Operators
Computer Numerically Controlled Tool Operators is the O*NET name for people who operate computer-controlled tools, machines, or robots to machine or process parts, tools, or other work pieces made of metal, plastic, wood, stone, or other materials. On the six-type interest model it reads RCI, meaning hands-on work with tools, machines or the physical world comes first, followed by orderly work with data, records and clear procedures. The preparation level is some preparation, typically a few months to a year of learning on the job. O*NET’s skill data points to operations monitoring, operation and control, and monitoring as the ones to build. You may also need to measure dimensions of finished workpieces to ensure conformance to specifications, using precision measuring instruments, templates, and fixtures. If you want hands-on work with tools, machines or the physical world, keep it on your list. If you need helping, teaching or caring for people, it may feel thin.
What they do
Operate computer-controlled tools, machines, or robots to machine or process parts, tools, or other work pieces made of metal, plastic, wood, stone, or other materials. May also set up and maintain equipment.
Main tasks
- Measure dimensions of finished workpieces to ensure conformance to specifications, using precision measuring instruments, templates, and fixtures.
- Set up and operate computer-controlled machines or robots to perform one or more machine functions on metal or plastic workpieces.
- Mount, install, align, and secure tools, attachments, fixtures, and workpieces on machines, using hand tools and precision measuring instruments.
- Review program specifications or blueprints to determine and set machine operations and sequencing, finished workpiece dimensions, or numerical control sequences.
- Stop machines to remove finished workpieces or to change tooling, setup, or workpiece placement, according to required machining sequences.
- Listen to machines during operation to detect sounds such as those made by dull cutting tools or excessive vibration, and adjust machines to compensate for problems.
Skills
- Operations Monitoring
- Operation and Control
- Monitoring
- Critical Thinking

Interest profile
O*NET rates each occupation from 1 to 7 on six interest types. The code RCI takes the three highest, and Realistic comes first here.
Preparation
Some preparation. Most people start with a high school diploma, then learn from experienced coworkers over a few months to a year.
Most-reported requirement in the O*NET survey: High School Diploma or the equivalent (such as a GED). This reflects what workers reported most often and is not a legal minimum. Licensing rules can differ by state or industry, so confirm what applies where you plan to work.
