5axis Curve Problems

[MLS]

Has anyone noticed that the curve 5-axis toolpath in X2 MR1 and MR2 seems VERY inconsistent?

 

In 9.1 it was difficult sometimes to get a clean normal to surface toolpath, but now it seems almost impossible sometimes.

 

I just brought a file into X2 MR2 that works fine in 9.1 MR0105 and regenerate the toolpath to get a hopping up and down and all around junk toolpath.

 

I would think you could bring a file straight in to X2 MR2 from 9, regenerate, and get the exact same results.

 

Am I missing something?

I have not noticed a problem with this at all and we use it daily, is there a specific problem, are you using solid, surface, nurbs or parametric splines, vector lines.

just looking for more detail so I can try it

I use 5 ax curve on many of our part trimming toolpaths and haven't seen a problem so far. Maybe put the file on the FTP and let us look at it??

Well I cannot access the FTP and this file is huge. Maybe I can isolate it down to just those toolpaths and geometry in the next day or so. Switched jobs again. Heh.

 

I am projecting a pocket-like chain (lines and arcs) to multiple surfaces driving it normal to those surfaces.

 

In V9 it worked decent, but now it starts the chain fine then will jump up at the surface edges and start at the other end of the chain. Some paths hop up and pick some point on the chain to start again seemingly for no reason whatsoever. It will even go the wrong direction along the chain.

 

I was thinking it was maybe a chain tolerancing issue, but I don't think that would change from version to version. I noticed on a part earlier I was trying to do something similar and had to project the chain geometry to the surfaces manually then in the toolpath project them normal to the surface instead of plane.

 

Thanks.
