Laser Cutting Processing Parameters Reference
A shop workflow for recording validated power, feed, focus, gas, nozzle, and pierce settings before they are reused in quotes or production programs.
Parameter Workflow
Keep programming, quoting, and QA in lockstep.
- 1. Capture machine documentation. Start from the active cut chart, controller library, OEM support note, or approved NC program for the exact material and finish requirement.
- 2. Validate with a coupon. Cut a sample, record edge quality, kerf, burr, discoloration, pierce behavior, and cycle time, then save the revision.
- 3. Push downstream. Feed the approved parameter set into the laser cutting calculator, reference gas setup with the assist gas guide, and convert feed with the cutting speeds reference.
How to Use This Reference
This page is a parameter logging checklist. It intentionally avoids public machine ranges because the correct settings depend on your exact optics, gas delivery, material, program, and acceptance criteria.
Parameter Inputs to Record
Store the source and validation status for each setting before it becomes a quote assumption.
| Input | Source to Record | Validation Check |
|---|---|---|
| Power setting | Machine cut chart, controller library, or approved program | Confirm penetration, edge condition, heat input, and repeatability on a sample cut. |
| Cutting feed | CAM post, NC program, or controller log | Time the cut and inspect dross, discoloration, taper, and dimensional result. |
| Focus position | Setup sheet, lens record, and operator adjustment log | Record top and bottom edge quality after the focus is approved. |
| Assist gas pressure and flow | Cut chart, regulator record, flow meter, or gas supplier documentation | Verify edge quality and gas consumption before using the value in cost models. |
| Nozzle and standoff | OEM setup table, nozzle inspection, and machine setup record | Retest after nozzle replacement, cleaning, crash, or alignment work. |
| Pierce routine | Controller program, pierce table, and timed sample | Tie pierce delay, ramp, lead-in, and pierce count to the cycle-time estimate. |
Material Setup Notes
Mild steel
Record whether the edge is allowed to oxidize or needs secondary cleanup before painting or welding.
Stainless steel
Record nitrogen supply, purity requirement, surface finish, and discoloration acceptance criteria.
Aluminum
Record supported alloy, reflectivity concerns, edge quality, and any coating or masking requirement.
Copper and brass
Record whether the machine supports the alloy, reflective-risk controls, and customer finish requirement.
Parameter Optimization Guide
Power and Feed Relationship
Change one variable at a time and record the resulting cut quality. A faster feed is useful only when the part still meets fit, finish, and inspection requirements.
Focus and Nozzle Control
Record focus, nozzle diameter, nozzle condition, standoff, and lens status together. Revalidate the setup after maintenance or a hardware change.
Gas Pressure and Flow
Use your cut chart, gas supplier data, flow meter, and edge inspection to approve gas settings. Keep gas cost assumptions visible in the quote.
Production Approval
Save the parameter set with the operator, date, machine, material record, sample result, and approval status so estimators can reuse it confidently.
Common Issues and Review Path
Issue: Excessive dross
Check gas delivery, focus, speed, nozzle condition, standoff, and material surface before changing the quote input.
Issue: Rough or wavy edge
Review feed, power, gas stability, beam quality, optics cleanliness, and whether the finish requirement changed.
Issue: Incomplete or interrupted cut
Check material thickness, power availability, focus drift, pierce routine, and surface contamination.
Issue: Discoloration or oxidation
Review gas type, gas quality, pressure record, leaks, feed, and whether secondary finishing should be quoted.
