I ran across this in the VR operators manual on page 71. http://diy.haascnc.com/sites/default..._June_2001.pdf

I guess it explains why I always have to fudge circles sizes vs speed on my 1996 haas vf. Is this the same on newer haas controls?(coldfire?)

For a 1" diameter cut at 100IPM and p113 at 375, that calculates to 0.9921 real diameter.

Has anyone played with any of the accel parameters? IE, 7, 113?
