DXF cut length & cutting time calculator

Drop in the customer's drawing: lines, arcs and curves are joined, holes are separated, and you get the total cut length, the pierce count and the cutting time for your machine speed.

Calculated in your browser; the numbers you enter are never sent anywhere.

Depends on material and thickness: 3 mm acrylic on a CO₂ laser is roughly 15–25 mm/s. Pierce time is spent at the start of every contour.

How is it calculated?

Lines, arcs, circles, ellipses and curves (splines, Béziers) are flattened into short segments with a very small tolerance; lines that meet end to end within 0.05 mm are joined into closed contours.

A contour inside a closed contour is a hole, and a contour inside a hole is a new part (even-odd rule). The cut length is the sum of all cut contours; the net area is the outer area minus the holes.

In DXF the unit comes from the $INSUNITS header; without it, mm is assumed and flagged. In SVG, if width and height carry a unit such as mm, cm or in, the drawing is scaled to it through the viewBox; without a unit it is read as pixels (96 dpi, 72 dpi for Adobe Illustrator files) and flagged. Red lines count as cuts and blue lines as engraving; a layer named CUT or ENGRAVE takes precedence.

Cutting time = cut length ÷ cutting speed + number of pierces × pierce time; engraving lines add engraving length ÷ engraving speed. The machine cost is that time multiplied by the hourly rate; material, setup and labour come on top.
