having trouble with the placement of the CC , and or CR ,I need to keep moving it as i get bigger, my flat on the long side 2.673 is aprox .488 so my CC moves .244 ea way then i was trying to just make a rad DR+ full Rad 1.098 R but i lost the number in a q some were and my radius is .244 short ? if i add this it wont work, so I now think I need to break it up to quadrants and feed to CL of short side 2.196 then on around like (my old shuzka knee mill with a bandit control) haven't had time to work It, I had to run production for a few days to get caught up with the past due

Thanks for looking

If you want to grind a rectangular slot, I would try to use a rectangular milling cycle only in the finishing type.
