Pushing my new OX to the limits. Check the feeds and speeds in the description and lemme know if you can beat me 
We’re you trying to make the non linear cuts on the left side of the square? Or were you going for a basic square pocket?
if that’s supposed to be a square pocket you have some problems.
I honestly don’t think so. My cut is bang on dimension wise and the walls are square. I will try this again with morph spiral machining which uses an arc instead of a 90* corner
16k at 100ipm is the proper math
