Problem with G41 cutter compensation in a volume milling

[RJ_FR]

Hello,

On my part, I use the volume milling function to create a slot diameter 4.2mm at the bottom of a side pocket in my part. For that I use an end mill diameter 4 and it works well.

But when I try to use the cutter compensation (G41), nothing changes in the Gcode file.

I have other sequences such as profile milling and the G41 is correctly converted into the GCode.

It never works with volume milling?

Does someone have an idea?

Thanks in advance

From what I can find it seems that the volume milling does not use cutter compensation. The discussions I've seen seem to indicated that people use volume milling to rough out the pocket, then a second toolpath to finish the walls with cutter compensation. For example, see this discussion:

Ok, thanks for the answer.

It's really weird. On a pocket milling function, i have the option for using the cutter compensation. But when i activate it despite of my entry and exit trajectory in straight line i have this warning and no G41 in the gcode.

KenFarley you are right, by doing research on the Creo help site I found this link https://www.ptc.com/en/support/article/CS179859

which specifies this :

Why this function appears in these sequences (volume milling and pocket milling) if it does not works ?!
