I only program in IGF mode. I have the OSP 5020L control. On the tool data page, are the x and z nose r comp numbers simply the radius on the insert? Do I enter the insert radius on both the x and z? Or am I mistaken? Also, do I have to enter a P number? What is the P number?I have been reading manuals for hours and I am still not certain. Any help would be greatly appreciated.
