Bevel Fiber Laser Cutting Machine
STR AP · Configure the cut around your joint drawing and edge requirements.
Bring weld-preparation geometry into the cutting decision.
A bevel fiber laser cutting machine uses a tilting cutting arrangement to produce specified inclined edges on metal plate. The STR AP review starts with the required joint section, material and finished dimensions, then matches the head, control, laser and handling package to that job.
AP machine, cutting process and component references from the existing STR page. Confirm the final supplied assembly in the technical offer.

When to review an AP bevel cutting configuration
Bevel cutting becomes relevant when the edge section is part of the component's function: a specified weld preparation, an inclined fit or an edge that would otherwise require a separate operation. The question is whether the proposed laser process can produce the required section consistently while keeping the part usable for the next operation.
Parts with defined joint details
Bring the drawing revision and section views. A label such as “45° bevel” alone leaves the angle reference, land, direction and finished dimensions unresolved.
Repeated edge-preparation work
Compare the existing route of cutting, handling, edge preparation and inspection with a proposed AP route. Count every operation that remains after laser cutting.
Mixed square and inclined edges
Mark which edges need a bevel and which remain square. Review supported operations, sequence and clearance with the offered programming package.

* Area and angular range are references published on STR's existing STR3015AP page, reviewed 22 October 2026. They are not a verified cutting-capacity chart. A head's angular envelope does not establish that every plate thickness, contour or joint section can be cut at its limit. Final configuration and trial conditions require confirmation.
Define bevel angle, root face and the finished contour
The angle of one bevel face is different from the included angle between two assembled faces. State the drawing's angular reference explicitly. Also define the root face, sometimes called the land: the remaining square portion at the edge, where the specified joint design includes one.
Top and bottom dimensions
An inclined face shifts the edge position through the thickness. Identify which face controls the external profile, hole size or assembly fit; a top-view outline is not a complete bevel definition.
Direction and datum
Mark the material side, upper/lower face and bevel direction. Include the datum used for angle inspection so the quotation, program and sample report describe the same geometry.
Land and transitions
Give the root-face dimension and its tolerance, if required. Define where bevels begin, end or change, including corner details and connections to square-cut edges.
Joint names need section views
V, Y, X and K are useful joint-description terms, but they do not replace a dimensioned section. Single/double sides, access and pass strategy need a review of the actual part.
A steeper bevel changes the section you must produce
Consider a hypothetical 12 mm plate with a 2 mm root face. The bevel height is therefore 10 mm. For a planar face at angle α from the plate normal, horizontal offset b = (t − c) × tan α and inclined face length l = (t − c) / cos α.
Illustrative geometry, not a cutting-capacity table
| Defined input or result | α = 30° | α = 45° |
|---|---|---|
| Plate / root face | 12 / 2 mm | 12 / 2 mm |
| Bevel height | 10 mm | 10 mm |
| Horizontal offset b | 5.77 mm | 10.00 mm |
| Inclined face length l | 11.55 mm | 14.14 mm |
These are invented geometry inputs. The calculation omits kerf, taper, compensation, thermal effects and actual process conditions. Face length is not a guaranteed laser cutting thickness or proof that AP can produce this joint. It also does not specify the included angle of an assembled joint.
The practical lesson is to submit thickness and angle together. A square-cut thickness claim cannot establish an inclined-edge result. Validate the proposed material/angle combination and its dimensional datums in the same trial.
Program the inclined edge as a complete cutting task
Head tilt is only part of the process
Bevel cutting combines the intended edge section with tool orientation, focus/height control, assist gas, path planning and part support. The program must account for where the physical head can move as well as where the laser intersects the plate.
Review corners, lead-ins, lead-outs and the cutting order on the actual nest. The chosen strategy should preserve the required faces while keeping the work stable during cutting and recovery.
External process background: Messer's bevel laser cutting explanation discusses adapting lead-ins, run-outs and cutting sequence to the bevel. It explains the general process; it does not establish STR's controller functions or supplied software.
Usable envelope and clearance
Check head/body clearance near sheet edges, clamps, slats and adjacent parts. Nominal table size alone does not define usable travel at every tilt and orientation.
Contours and local features
Internal profiles, small radii and bevel transitions can require different strategies from a straight outside edge. Include the smallest critical feature in the trial drawing.
Support and release sequence
Review the order of internal and external cuts, remaining support and how parts will be removed. A loose or tilted part can interfere with subsequent operations.
Recovery after interruption
Agree how an operator checks the work and resumes after a stop. Confirm supported recovery functions and their training scope in the proposed control package.
Specify the head, axes and programming package together
The AP images below identify component references used on the existing page. Select the actual head, motion/control package and laser source against the application; the commercial offer should list the supplied manufacturers, models and licenses.
Tilt and rotary assembly
Identify the actual axis arrangement, travel limits and calibration procedure. Review how orientation and positional compensation are maintained in the supplied system.
Control and programming
Check file import, section definition, bevel assignment, simulation, compensation and operator editing. List included functions and any separately licensed tools.
The laser source, chiller, gas system, extraction and machine structure also belong in the configuration. A controller screenshot or branded head photograph is not confirmation of the delivered bill of materials.
Choose the process by material, thickness and edge use
| Material / requirement | What to provide and verify |
|---|---|
| Carbon steel plate | Grade, scale/surface condition, thickness and joint detail. Define acceptable oxide, dross and remaining cleanup for the downstream operation. |
| Stainless steel | Alloy, cosmetic face and required edge condition. Review assist gas, surface handling and the joining/finishing requirements. |
| Aluminum alloys | Exact alloy and condition, part geometry and edge requirements. Confirm the proposed laser/head package and representative trial. |
| Other alloys or coatings | Submit material information for explicit application and extraction review. Do not infer suitability from a steel sample. |
| Increasing thickness or angle | Review the combined condition, feature size and required face quality; do not extrapolate a square-cut capacity. |
A process that cuts through the plate may still fail the joint requirement. Inspect the angle, root face, surface condition and fit, and define whether finishing is permitted before the next operation.
Review the part families that actually need inclined edges
Fabricated frames and weldments
Start with the approved joint details for plates that will be assembled. Check the required fit and datums, including any edge that remains square for locating or clamping.
Brackets, ribs and reinforcement plates
Identify the short contours, inside corners and support conditions that can make the part more demanding than a long straight bevel sample.
Repeated plate-preparation work
Use recurring parts to compare cutting plus preparation with the current route. Record setup, reorientation, inspection and handling for a fair batch comparison.
Inclined mating edges
When the edge serves a fit rather than a weld, define the contact surface and functional dimensions. Do not replace fit requirements with a generic weld-preparation description.
Inspect the bevel section, not just a sample photograph
These images come from the existing AP page. They show sample geometry and presentation; no material grade, measured angle, thickness, cut time or acceptance result has been verified from the photographs.
Ask for a traceable application trial
Record drawing revision, material grade and measured thickness, stock condition, machine/laser/head build, software version, assist gas and the agreed process. Identify each sample and where measurements were taken.
Include straight edges, corners, transitions and the smallest relevant feature. Inspect repeat samples and relevant locations across the work area where the agreed acceptance plan requires them.
Agree what makes the prepared edge acceptable
| Feature | Acceptance discussion |
|---|---|
| Bevel angle | State datum, nominal value, tolerance, measurement tool and locations; distinguish one face from an included joint angle. |
| Root face / land | Specify dimension, variation allowed and how it is measured along the relevant edge. |
| Finished contour | Identify controlled top/bottom dimensions, internal features and position relative to the drawing datums. |
| Bevel surface | Define acceptable striations, dross, oxide, local defects and any permitted cleanup with a repeatable inspection method. |
| Corners and transitions | Inspect start/end regions and transitions between square and inclined edges, not only the middle of a straight cut. |
| Assembly and joining | Check agreed fit-up and the buyer's preparation requirements. Qualify the downstream welding process separately where required. |
| Repeatability and cycle | Agree sample quantity, run conditions, inspection records and whether handling, cleanup and rework are included in the reported time. |
Laser bevel cutting prepares an edge; it does not by itself qualify a weld, prove joint strength or remove every cleaning requirement. Use the buyer's approved joint detail and welding requirements to define the preparation scope.
Compare the complete preparation route before selecting AP
Compare the same part, section and acceptance result. Review the current sequence and the proposed AP sequence, including any operations that remain outside the machine. Avoid judging cost from cutting time alone.
| Task | Record for both routes |
|---|---|
| Programming and setup | Drawing preparation, section definition, fixtures, calibration and first-piece approval. |
| Cutting and preparation | Actual process time, pierces, passes and any separate edge-preparation operation. |
| Handling | Moves between stations, part reorientation, access, sorting and recovery. |
| Finishing and inspection | Dross/oxide removal, permitted touch-up, measurements, fit checks and rework. |
| Operating resources | Gas, power, consumables, labor and maintenance under the compared conditions. |
Already have a representative part and current preparation route?
Prepare an AP application reviewIf your normal work only needs square-cut sheet profiles, start with the A single-platform configuration. If access and sheet turnover dominate the job, also compare the B exchange-table layout. These pages address different selection tasks; their specifications do not establish AP performance.
Plan for calibration, optics and service access
Head and axis checks
Follow the supplied inspection and calibration procedure, particularly after a collision, component change or maintenance event. Confirm the operator checks and escalation process with the service team.
Optics, nozzles and ceramic parts
Use the parts specified for the offered head. Keep protective optics and nozzle condition within the supplier's procedure; consumption depends on process and operating conditions.
Gas, cooling and extraction
Confirm purity, pressure/flow requirements, cooling conditions and extraction maintenance for the final configuration. Arrange service access without obstructing loading and head travel.
Software and records
Define backups for programs, parameters and calibration records. Confirm included updates, support channels, spare-parts identification and the response arrangements in the contract.
Maintenance intervals, consumable life, warranty terms and service response need the actual equipment manual and commercial agreement; they are not inferred from gallery images.
Make the technical and delivery scope reviewable
Before ordering, align the technical sheet, sample report and commercial offer. Identify what is included in the machine package and what the workshop must provide.
- Technical package: model, layout, laser/head/axis/control build, software licenses, utilities and agreed application envelope.
- Quality plan: drawing revisions, sample conditions, measurement methods, tolerances and acceptance responsibilities.
- Workshop preparation: complete footprint and access, foundation/load requirements, electricity, gas, cooling, extraction and the supplied safeguarding arrangement.
- Handover: commissioning scope, operator/maintenance training, manuals, calibration records, spare-parts list and support contacts.
- Commercial scope: lead time, packing, transport responsibilities, installation, warranty and excluded services in the dated offer.
Send the receiving workshop's location and available utilities with the drawing. This allows the proposal to address the installation context as well as the cutting task.
Questions before choosing a bevel laser cutter
What is the difference between bevel and square laser cutting?
A square-cut edge is nominally perpendicular to the plate faces. Bevel cutting intentionally produces an inclined edge section. The section requires angle, orientation and dimensions through the thickness, in addition to a top-view contour.
Does a ±45° reference mean every plate can be cut at 45°?
No. An angular envelope does not establish cutting capacity for every thickness, material or contour. Confirm the angle convention, usable envelope and the requested combination in an application trial.
Can AP make V, Y, X or K preparations?
Submit dimensioned sections rather than relying on a joint name. STR needs to review side access, root face, contours, machine/head configuration, software and pass strategy before confirming the requested preparation.
Does bevel cutting remove all grinding before welding?
That depends on the required edge condition, actual cut result and the buyer's welding preparation requirements. Agree permitted cleanup and test the complete route. A photograph cannot prove a universally ready-to-weld edge.
Which laser power should I choose?
Provide material grade, usual/maximum thickness, bevel section, smallest features, required edge condition and output. Select the laser, head, gas and motion/control package together; power alone does not define the result.
Can the same setup cut square and bevel edges?
Identify both edge types in the drawing. Confirm supported operations, tilt positions, transitions and programming functions in the proposed package, then include relevant combinations in the sample trial.
How should bevel accuracy be checked?
Agree angular datums, top/bottom dimensions, root-face dimensions, measurement tools and sample locations. Machine-axis accuracy is not a substitute for a finished-part acceptance report.
What should I send for a quotation?
Send a dimensioned drawing and joint sections, material grade and thickness, blank size, output, required inspection and workshop location/utilities. Include the current preparation route if you want to compare complete production cost.
