Hello all,

I'm currently working with a FANUC 0M-C CNC Mill and I have a question regarding its cutter compensation on the OFFSET page. I would like to know what I exactly need to input as a value for the radius compensation. Does the value need to be the tool's radius plus the compensation or only the compensation.

For example, I currently have a model with a Pocket which has a diameter of 26mm but when i run the program on my FANUC the Pocket diameter is 26.15mm. The tool diameter is 20mm. What offset value do I need to insert so it compensates and becomes 26mm? I've tried all kinds of values - positives, negatives, G41 and G42 but I feel like the machine is not reading the compensation at all or there is some other kind of problem. Any help would be greatly appreciated.

Here is a snippet of my GCODE if needed:
N1590 G1 X-.022
N1600 G0 Z0.
N1610 X0. Y7.
N1620 G1 G42 D10 Y9. F150.
N1630 Z-1.455 F100.
N1640 G2 X13. Y-4. I0. J-13. F150.
N1650 X0. Y-17. I-13. J0.
N1660 X-13. Y-4. I0. J13.
N1670 X0. Y9. I13. J0.
N1680 G1 G40 Y7.

OFFSET > TOOL OFFSET page, find Tool 10
If you use full radius compensation (geometry only):
Set D10 = 9.925mm instead of 10.000 (10mm - 0.075mm)
