Dear Friends

We are having Leblond Makino Milling with Fanuc 0MF- Mate control. We are getting 0.5 offset in X Axis in Circular Interpolation. We are checked the Wear Offset, Geometrical offset all are O.K. We took the New Geometrical offset G55 And Checked Positioning is O.K. We observed positioning During Machining is as per Program. We are using 8.5mm Endmill.

We are unable to understand How it is getting 0.5mm offset in Center in X Axis

Please post the section of code that's showing this problem.

Try this. Block 128 looks to be incorrect.
