Fiber Laser Cutting Thickness, Power & Assist Gas: Validation Matrix
Aogeo Laser’s current sheet-fiber platform spans 1500–12000 W, but power alone does not define cutting thickness. Use this validation matrix to record material, thickness, gas, process settings and measurable cut-quality results before selecting a configuration.

Scope note: This is a validation worksheet, not a universal maximum-thickness chart. A published power range cannot predict cutting capacity without defined material, optics, assist gas, motion and acceptance conditions.
Aogeo Laser’s current fully enclosed sheet-fiber platform spans 1500–12000 W and is described for carbon steel, stainless steel, aluminum, brass and other metal sheet. Use that range only as a platform starting point. Review the broader laser cutting equipment family and sheet-fiber category before fixing a route.
Start with the evidence boundary
| Published fact | What it supports | What it does not support |
|---|---|---|
| Current sheet-fiber platform range: 1500–12000 W | Selecting candidate equipment for testing | A guaranteed thickness, speed or edge-quality value |
| Metal-sheet projects may evaluate oxygen, nitrogen, air or another approved assist gas | Creating a controlled candidate-gas test plan | A universal material-to-gas recommendation |
| Cut quality depends on material, thickness, focus, gas, motion and extraction | Defining the variables that must be recorded | Selecting a machine from watts alone |
| Sample DOE and agreed acceptance criteria determine the final configuration | Approving a documented process window | Replacing tests with an internet chart |
Project input form
| Input group | Required project data |
|---|---|
| Material | Exact grade, condition, coating, supplier or batch, surface state and thickness range |
| Part geometry | Drawing revision, sheet size, contour, smallest hole or feature, corner requirement and pierce locations |
| Cut acceptance | Dimensional tolerance, kerf, perpendicularity or taper, roughness, burr, dross, oxide limit and heat-effect limit |
| Production target | Required takt time, batch size, nesting plan, loading method, shifts and changeover frequency |
| Gas infrastructure | Candidate gas, specified purity, available pressure and flow, supply stability and acceptable operating cost |
| Inspection | Measurement method, acceptance threshold, sample size, downstream operation and pass/fail authority |
Material-specific context is available for steel, stainless steel, aluminum and copper. These guides define evaluation inputs; they do not publish substitute thickness limits.
Assist-gas candidate log—not a recommendation chart
| Candidate | Record before testing | Measure after testing | Release status |
|---|---|---|---|
| Oxygen | Grade or purity, pressure at the machine and nozzle, nozzle geometry, flow and supply condition | Speed, edge appearance, oxide condition, kerf, taper, burr, dross and heat effect | Unverified until the defined sample passes |
| Nitrogen | Grade or purity, pressure at the machine and nozzle, nozzle geometry, flow and supply condition | Speed, edge appearance, kerf, taper, roughness, burr, dross and gas consumption | Unverified until the defined sample passes |
| Compressed air | Air quality, dryness, oil control, pressure stability, nozzle geometry and flow | Speed, contamination, edge appearance, kerf, burr, dross and operating stability | Unverified until the defined sample passes |
| Other approved gas | Engineering rationale, compatibility, safety review, purity, pressure and supply controls | All agreed quality, safety, cost and repeatability metrics | Requires project-specific approval |
Fiber cutting validation matrix
| Test ID and fixed inputs | Machine and process settings | Measured results | Decision |
|---|---|---|---|
| T-001 Exact material grade, lot, surface condition, measured thickness and drawing revision | Platform revision; commanded and measured power where available; optics, focus, nozzle; gas, purity, pressure and flow; speed and pierce settings | Attach kerf, taper, roughness, burr, dross, heat effect, cycle time, gas use and inspection record | Pass, revise or reject against the agreed criteria |
| T-002 Repeat at an expected material, thickness or batch limit | Record every changed variable; do not combine unrecorded parameter changes | Compare quality, repeatability and operating stability with T-001 | Define the tested boundary or schedule another controlled trial |
Do not publish a numeric result as a reusable capability claim unless it identifies the tested machine configuration, material grade and condition, thickness, optics, nozzle, gas condition, speed, focus, inspection method, sample count, test date and approving engineer.
Define acceptance before the first cut
- Kerf and contour accuracy
- Perpendicularity and taper
- Edge roughness and appearance
- Burr, dross and recast layer where applicable
- Heat-affected zone and microcracks where applicable
- Piercing behavior, cycle time and gas consumption
- Repeatability and continuous-production stability
- Downstream bending, welding, coating, assembly or functional acceptance
The laser cutting process guide explains why these variables must be evaluated together.
From test matrix to released process window
- Freeze the material specification, thickness range and drawing revision.
- Agree on measurable quality thresholds and the inspection method.
- Select a candidate platform without converting rated watts into a thickness promise.
- Run a controlled DOE and retain every machine, optics, gas and motion variable.
- Confirm repeatability across the agreed sample size and production duration.
- Release only the approved parameter window, configuration revision and acceptance record.
Aogeo Laser’s sample testing and process validation workflow covers test planning, parameter DOE, result comparison and process reporting.
Frequently asked questions
Can laser power alone determine maximum cutting thickness?
No. Material grade and condition, beam delivery, focus, nozzle, assist gas, speed, motion accuracy and the required edge quality all change the result.
Which assist gas should I choose?
Treat oxygen, nitrogen, compressed air or another approved gas as controlled test candidates. The final choice must be based on the project’s edge, oxide, burr, speed, cost, safety and downstream-process requirements.
What should I submit for a configuration review?
Provide the exact material and thickness range, drawings, minimum features, tolerance and edge targets, production rate, available gas infrastructure, inspection method and representative samples.
Build a project-specific matrix
Submit your materials, drawings and acceptance criteria for a test plan and configuration review. The resulting engineering record—not a generic online table—should define the approved cutting window.
