Disable plunge type engage moves

Disable plunge type engage moves

Disable plunge type engage moves

(OP)
In Z-level profile, the closed area engage setting is helical, and if there is no room for the helix, I would like ramp on shape. If the ramp length would be too small, there should skip cutting region.
How can I avoid plunging?
I am on NX8.5.0.23
Thanks in advance

RE: Disable plunge type engage moves

Have you set the Minimum Ramp Length?
This will prevent the tool from plunging in to an area if there is not enough room for the selected engage method.

Thanks for Your reply, The minimum ramp length is 20% of tool diameter, and if I use a lower value, the plunge move really disappear.
But, if I set the ramp length such a small value, the machine will terribly shake.. The 20% value is already small. In the attached image, You can see all the problems I have. I need to manually edit this path. At the small region, there can be a ramp outside form the cut region, and it can be much longer, then 10 or 20 percent.
In the green circle, You can see, what I can accept. If I set smaller minimum ramp length, the helix diameters will be smaller, so we get back to shaking of the machine.
In the next levels, there are open regions, not any disturbing geometry nearby, but there are "ramp on shape" type engage moves, and the need of many more hand-editing..
So it seems, that all option leads to hand editing. And as Capnhook said here : "Hand-editing is the primary cause of machine crashes."

Please open a call with GTAC and submit the part, so that somebody can take a deeper look at it.
