C axis unwinding on Haas 5X

Hi All,

*I'm using PowerMill 2020 on a Haas 5 axis trunnion type of machine.

*I'm wireframe swarf cutting the entire periphery of a part with a constant

5 degree draft.

*In the simulation it all looks good.

When executing on the machine*it leads in,machines around until reaching the point of passing C zero

where it rotates C360.0 back to the same position it was at , then continues the path and leads off of the part.

During this repostioning it does not lift z or reorient the A/C axis positions to prevent gouging.

Is this a setting in the post , the PM software, or a machine setting?

It would be either a post or programmer error... I'd lean toward a programming error.
.... long time since using PM, but look for a "Retract between Cuts" or possibly a "Keep tool down" setting
