What I need to do is put the workpiece in the mill vise and trim from the top down at a 70 degree angle. I may actually cut the angle on my chop saw and use the mill to get the cut more precisely accurate. Or maybe not.
The triangle has an acute angle adjacent to the right angle of 70 degrees. Starting at the other adjacent angle I need to slide the round nose mill down the slope until I have moved .381" in Y. Starting at z=0 and y=0, how do I compute the ending point for z?
