Kerf gauge with setting data

Laser cutter Kerf gauge!

This is used to determine the kerf when laser cutting (kerf= the material that will be cut away by the beam thickness).

1) PMMA (Acrylic) pcs cut 2 mm thick cut with diffrent parameters
2) The first have cutting speed of 15 mm and 25% power ( 150 w x 25% = 37,5 w).
3) Gave me a kerf of 0.007 in or 0,175 mm.
4) The second had a cutting speed of 15 mm and 20% power ( 150 w x 20% = 30w).
5) Gave me a kerf of 0,005 in or 0,125 mm.


1) Masonite 3,1 mm thick.
2) Cutting speed 15 mm and 35 % power (150 w x 35% = 52,5 w).
3) gave me a kerf of 0,003 in or 0,075 mm.

I put a pen mark on the kerf I get and then I save the pcs , I put them in a plastic pocket, in a book cover.
Then I can go back and look at the quality of the cut burn marks and so on.

The zip file includes DXF file and Solidworks 2015 file.
