RE: my cnc
here is a test on a wing profile..I did not cut fully, it was just to test the movement of the machine for this kind of shape.
the curvature seems ok, just the trailing edge is little bit cut probably due to little movement of the support.
I have seen that depending that there is some speed at which the cutter vibrate little bit...depnding on feedrate and depth...
I think on that point there is a need of little practice before getting not burned wood and with perfect surfacing.
