Toolpath lines to arcs

When I try to do helical engage to it outputs tool movement as straight lines. I would like to have helical engage movement as arcs (G2 or G3). How I can change that NX does that with arcs? I have same problem when working with 4th axis.


Re: Toolpath lines to arcs

Has your post-processor output of helical moves enabled, see the circular move section in PB or PC, depending on what you use?

Is that picture what you mean with PB or PC? I have tried to find some place to enable helical moves from my post-processor but I have not found it.

Re: Toolpath lines to arcs

Import the custom command PB_CMD_helix - there are some settings in there that allow configuration. If your post kinematics are table type - NX should give you circles.
