Drawings for laser cutting and bending
Clear documentation connects the designed part to production. Supply the cutting geometry and a drawing of the finished bent part at the same revision.
Files and essential information
The DXF defines the cut contours; the production drawing defines the finished-part requirements. A 3D model helps with complex shapes but does not replace specified tolerances.
- Identify the material, thickness, quantity, units, part number and revision.
- Supply a 1:1 DXF with closed contours and no duplicate lines, text or dimensions in the cutting layer.
- Include a PDF with functional dimensions and tolerances; add an agreed STEP model where useful.
Dimensions of the formed part
Provide the necessary views and identify the projection method. Use the appropriate symbol for first-angle projection; do not rely on view placement alone.
- Specify the inside radius, final angle and direction of every bend.
- Distinguish inside from outside dimensions and define datums for critical holes and mating surfaces.
- Agree the flat pattern with the actual tooling and production bend data.
Holes, threads and visible surfaces
A laser-cut opening may differ from the final machined hole. Specify thread and countersink sizes, positions, depths and machining sides in the drawing; agree the pilot-hole geometry in the DXF.
- Mark the cosmetic side, protective film, finish and deburring requirements.
- If cut-start marks or micro-joints affect function or appearance, agree their permitted locations.
Before placing the order
Check that DXF, PDF and model share the same units, contours, orientation and revision. Confirm the feasibility of short flanges, holes near bends and the manufacturing sequence before production release.
