Laser Cutting Estimator

Material from the catalog (density), thickness, geometry (DXF/PDF or length+piercings), part bounding box, sheet format (or scrap %), power, gas, quality, rates and secondary operations if applicable. The checklist shows what's missing.

Places the part's bbox on a grid over a standard sheet (e.g. 3000×1500), with gap, edge margin and optional 90° rotation. Calculates parts/sheet, number of sheets and allocates the material cost. It doesn't nest irregular shapes (true-shape): for that you still need Deepnest or another advanced nesting tool.

Adds cutting time (length ÷ speed), piercings, setup and rapid moves. With nesting, setup is split by number of sheets. The suggested speed comes from the material × power × gas × quality table.

Yes. The selector uses the same catalog (EN, DIN, AISI, UNS…). Picking a sheet loads its density and the corresponding laser-cutting family. Titanium, nickel, cobalt and plastics have no speed table: you must enter speed and pierce manually. The €/kg remains editable per shop.

The tables are calibrated at ~4 kW. More power raises the suggested speed and reduces pierce time. O₂ usually speeds up steel; N₂ is the reference for stainless/aluminum; air tends to be slower. Fast quality raises speed; fine quality lowers it. Changing the gas suggests a typical €/h.

Yes, if it's a vector PDF exported from CAD. We extract the paths, ask for the scale (points→mm, units=mm or calibration by a known width) and apply Drawing Doctor. A scanned PDF or photo won't do for a firm quote: ask for a DXF or vector PDF.

We measure cut length, piercings and bounding box; we clean duplicates/micro-gaps; rectangular sheet nesting; secondaries and margin. We don't do true-shape nesting yet. In PDFs we filter vector paths and one part per page works best.

Yes. In secondary operations you define folds (€/unit), welding (€/m), finishing per m² (2 sides of the bounding box) and other fixed costs. They are added to the cutting/material cost before margin.

Yes: machine, gas, sheet (by sheet nesting or bbox×scrap), secondaries, margin and quantity discount. With nesting, the material kg is that of the sheets used split across parts. Rates, process and sheet are saved in the browser.
