Dont know how to calc with tool nose radius...

How mastercam calc:
Z-4.685
Z-5.766

[cogsman1]

tool radius - (tool radius x tan (angle ÷ 2) ) = Z axis comp.

I added a formula, but I can't get the right answer.


I think I must use cos/sin but where.

Mastercam code:
Z-4.685
Z-5.766

[FanucOkuma]

tool radius - (tool radius x tan (angle ÷ 2) ) = Z axis comp.

This.

0.8 - (0.8 x TAN 22.5) = 0.4687mm

0.03125 - (0.03125 x TAN 22.5) = 0.0183”

Or you could be lazy like me. I kept one of our CHNC programming books from when I started back in 1985. In the back of the book it gives X and Z tool compensation in one degree increments for several different size radii. Maybe you could find a used book or ask me to fax copies of the pages to you.
