CNC Laser Operator (Computer Numerical Control Laser Operator)
Computer Numerically Controlled Tool OperatorsDescription
Set up, operate, and maintain CNC laser cutting/engraving machines to cut, trim, or mark parts from metal, plastic, wood, and other materials. Load and edit programs; adjust power, speed, focus, and assist gas; verify dimensions and edge quality; and maintain optics, chillers, and fume-extraction systems.
- • Measure dimensions and features of laser-cut or engraved parts to verify conformance, using calipers, micrometers, gauges, and templates.
- • Replace worn nozzles, lenses, protective windows, and other consumable optics.
- • Load, align, and secure sheets or workpieces on the laser bed using clamps, pins, or vacuum fixtures.
- • Observe cut sparks, kerf, and alarms to detect issues such as poor focus, dross, or vibration, and adjust to correct problems.
- • Adjust laser power, speed, frequency, focus height, and assist-gas pressure when programs are faulty or conditions change.
- • Pause or stop machines to remove parts, clear scrap, change nozzles, or adjust setup according to the cutting sequence.
- • Lift and position materials and finished parts manually or with carts, hoists, or pallet systems.
- • Edit nests and toolpaths to resolve problems encountered during operation and save revised programs.
- • Determine appropriate cutting parameters, pierce settings, and lead-ins based on material type and thickness.
- • Load and call up CNC programs at the controller to start operations.
- • Verify assist-gas supply and flow and ensure the chiller and fume-extraction systems are operating during cutting.
- • Enter material thickness, nozzle size, origin, and other setup data into the control panel.
- • Set up and operate CNC laser cutters/engravers to perform cutting, trimming, or marking on metal, plastic, wood, or composites.
- • Confer with supervisors, programmers, or engineers to resolve malfunctions or quality issues or to obtain production approvals.
- • Review blueprints, CAD files, and job travelers to set machine sequencing, part dimensions, and nesting layouts.
- • Monitor machine status and control panel displays and compare readings to specifications to detect malfunctions.
- • Monitor and maintain laser chiller temperatures, assist-gas manifolds, and dust or fume-collection equipment.
- • Perform routine maintenance, including cleaning lenses and mirrors, replacing filters, and checking beam alignment.
- • Sort, stack, and tag finished parts; place items on pallets or conveyor systems.
- • Clean machines, optics, slats, and parts; remove slag and empty scrap bins.
- • Select and load programs or retrieve them from USB or network storage at the machine controller.
- • Transfer programs from CAM or servers to CNC modules using computer network links.
- • Stage materials, nozzles, and programs to set up upcoming jobs while machines are running.
- • Implement program changes and enter new specifications using the controller or CAM software.
- • Create simple laser programs, nests, or engraving text at the machine control.
- • Inspect cut edges, holes, and micro-features for burr, taper, or heat-affected zones, using magnification when required.
- • Apply laser marking for part identification and record serial numbers or heat lots on finished parts.
