Hello

I have the following problem: When I mill a part with TCPM(M128) and then I continue turning the C axis with for example CP IPA+90 IC+90 DR+, then the feed gets really slow ( the smaller the radius the slower the feed)
I actually have very fast pivoting axes, the same radius programmed in CAM (divided into linear pieces) also goes fast, and even when I divide the parts in a parameter program it’s still fast.
E.g. with a Hermle is’s also really fast even though I have a lot faster rotational axes.
So that’s why I believe it’s due to the settings in the MPs.

Thank you
