CNC Router Operator (Computer Numerical Control Router Operator)
Computer Numerically Controlled Tool OperatorsDescription
Set up and operate CNC routers to cut, drill, pocket, and profile wood, plastics, composites, and soft metals per blueprints or CAM programs. Load and secure materials, select and change tooling, run and adjust jobs, inspect parts, and perform routine maintenance and basic program edits.
- • Measure dimensions and features of routed parts with calipers, tape measures, and gauges to verify specifications.
- • Remove and replace dull or broken router bits, collets, and tool holders.
- • Mount and secure sheets or panels on the vacuum table or with clamps and align to datum edges.
- • Install, align, and tighten tooling; verify tool length and diameter with a touch-off plate or tool setter.
- • Listen for chatter, vibration, or spindle load changes and adjust to correct issues.
- • Adjust feeds, speeds, spindle RPM, stepdown, or stepover, and change tools when programs or materials require.
- • Stop the router to unload parts, clear tabs, change tooling, or reposition workpieces per the setup plan.
- • Lift and position large sheets using carts, lift tables, or assist devices to protect surfaces and operators.
- • Edit toolpaths or offsets at the controller to resolve problems and save revised programs.
- • Calculate feeds and speeds, chip load, and cut depths based on bit type and material.
- • Load G-code or machining files, set work coordinate zeros, and start the program.
- • Verify vacuum hold-down and dust extraction; apply mist coolant when routing aluminum or composites as specified.
- • Enter part thickness, offsets, and tool data into the control; set Z zero with a touch probe or feeler.
- • Set up and operate CNC routers to cut, drill, pocket, profile, and engrave wood, plastics, composites, and soft metals.
- • Review drawings, nest layouts, and CAM notes to determine operations, sequencing, and finished dimensions.
- • Monitor machine status, spindle load, and controller displays; compare readings to specs to detect malfunctions.
- • Manage dust collection and vacuum systems; check seals, gaskets, and filters for proper performance.
- • Perform routine maintenance; resurface spoilboards, lubricate guides, and replace worn belts, seals, or collets.
- • Sort, label, and stack finished parts or kits on pallets or carts to prevent damage and mix-ups.
- • Clean the router, table, and tooling; vacuum chips and dust and dispose of waste safely.
- • Transfer programs via network or USB and retrieve stored jobs from the controller.
- • Stage materials, tooling, and fixtures for upcoming jobs while the router is running.
- • Update CAM parameters, nesting, and tool libraries; repost and load revised G-code as needed.
- • Create simple drilling, trimming, or engraving programs at the controller for quick jobs.
- • Inspect edge quality, hole size, and surface finish; deburr, sand, or remove tabs as required.
- • Perform dry runs or air cuts to verify clearances, clamps, and paths before cutting production parts.
- • Communicate with supervisors, programmers, or engineers to resolve issues and obtain production approvals.
