There’s a good discussion here.

Small variation between x and y cuts, so how do I calculate kerf?

What is an acceptable cut variation between x and y coordinates? For example, I keep cutting squares, but they come out as rectangles. I spent the last hour or so reading forum posts with similar problems, but I just needed to know if my results are normal. Usually there’s a variation of 0.05mm / 0.002" between x and y axis cuts. A 20mm x 20mm square comes out as 19.87mm x 19.92mm (X x Y). I tried rotating the wood piece 90 degrees to change the direction of the grain, and the results were simil…

In-general, it’s accurate to about 1/1000" in both directions. 1/64" is not typical.
