Free Laser Cutting Tools

Laser cutting rewards people who measure. The difference between a profitable job and a favour is usually a handful of numbers: how many parts fit on the sheet, how long the cut really takes, how much kerf your machine removes, and what margin you applied.

These tools exist to make those numbers quick. They run entirely in your browser, they need no account, and every result is computed from the figures you enter — no default “industry averages” pretending to be your workshop.

Start with the tool that matches your question

“What should I charge for this part?”

The laser cutting cost calculator splits a part into material, machine time and labour, then applies your target margin to the selling price. That last detail matters: applying 40% to cost gives you a 28.6% margin, not 40%.

“How many parts fit on a sheet?”

The sheet yield calculator returns parts per sheet, material utilisation and the number of sheets a run needs. It tests both orientations, because rotating a part by 90° often adds several pieces per sheet for free.

“Why do my finger joints not fit?”

Almost always kerf. The kerf and finger joint calculator converts a measured kerf into the slot width you should draw, with clearances for press, snug and slip fits.

“Why did my file import at the wrong size?”

SVG and bitmap files carry their own units. The units and resolution converter converts mm, cm, inches, mils and pixels at any DPI so you can check scale before cutting.

How to get useful answers

Use your own numbers, not examples. Sheet price is what you actually pay including delivery. Cut speed is what your machine actually runs in this material. Machine rate should cover the machine’s replacement cost, maintenance, lens and tube wear, extraction and floor space — not just electricity.

If you are unsure about cut length, export the file from your CAD software and read the path length in the document properties. Most tools show it.

What these tools do not do

They do not nest irregular shapes, simulate heat distortion or replace your machine’s control software. For rectangular production work and quick quoting they are usually enough. For complex mixed-shape sheets, use dedicated nesting software and treat these calculators as the commercial layer on top.

Next steps

• Read how to measure kerf and compensate for it once, properly.
• Apply the five nesting rules that cut sheet waste.
• Fix your pricing with a repeatable pricing formula.
