Solidcam: properly adjusting postprocessor arc interpolations, axis accelerations, deccelerations and velocities to achieve smooth motion during milling.

I've got a problem when there is automatic recognization involved in cam process (for instance when I use silhouette recognization on outter contour on part, or in iMachining) and my machines start "stuttering" they move jerky and tend to break tools more often or leave nasty milling marks and dents from where they stopped or slowed down on part.

I've tried doing something about it in the postprocessor vmid file

but I'm just tapping in the dark, so please, can you tell me which values need to be imput so I can achieve smooth machine motion during milling.

guys I still need pointers on this, especially because of imachining, it's breaking my tools, those jerky motions when moving in high feed - very bad for your mills.

I need somehow to make the arc movements smoother, I've got no problems when picking out contours by hand, only when I use silhouette or iMachining, those operations make my tool path movement very jerky on both new machine and old ones so I blame postprocessor settings.

I'm thinking these settings are off, but now sure for how they should be set correctly:
