5 axis contour - tool orientation jitter and skipped passed

Hi,

I'm currently experimenting with 5axis toolpath and this one seems to be trickier than expected: 4 concentric circles on a sphere.

This shown the default result with 0.01mm tolerance. The tool orientation is not what I'm after. Sure, the model gets triangulated and every facette has its own normal. So I increased the tolerance to 0.001mm.

Thats better, but still rather jittery for a nice cut. So 0.0001mm tolerance:

tool orientations look good now, but some issues arise:

1) new warning box shows up (Warning: One or more passes were completely skipped.) and only 2 circles are part of the toolpath now.

2) I dump-posted the file and found more than 500 linking moves

( 500+ calls of onMovement(MOVEMENT_LINK_TRANSITION /*transition*/) )

 

Something is not right here.

 

Is there a good way to get suitable tool orientations without increasing the triangulation tolerance that much? Some kind of averaging might already help (without being ideal).

 

Thanks,

Stefan

Go into "Compare and Edit" (right click on the toolpath to get there) and search for "Surface Triangulation". Set it to "tolerance * 0.05"

@seth.madorethanks. will do.

I didn't know about that additional triangulation tolerance.

 

This is going to increase calculation time quit a bit isn't it?

 

Thanks,

Stefan

It didn't seem to add too much to this piece
