Contour toolpath not changing direction

[u1939787]

Hi everyone,

After many tryouts, I am having a problem which seems to be unsolvable. I hope you can support me with this one..

I'm currently working on a simple geometry, an inversed cone, and I am looking to machine only the surface, so following two cicles (a bigger one at Z=0 and a smaller one at Z=-50)

The problematic is that, after asking a contour (or another operation) to perform the desired toolpath, it does not go Clockwisw + counterclockwise for each circle, even if I define correctly the Direction "both ways", but if I set the Direction to be Climb or Conventional, it does indeed work, changing the tool direction from one to another.

How can it be solved? I can seem to find a solution.. Working with a Geodesic operation it works, but I need to work under a regular stepdown and not a stepover...

I have already tried all the Operations but none of them does work, even though it should...

Why not ramp or spiral?

I have already tried them and performed the machining on the surface with both ram and spiral but i'm looking for a direction change after each circle performed, so that greater simmetry is achieved.

With the "both ways" selection, should be done with changing direction but it does not do it..

Both ways is to allow it to ramp back and forth, not force it to change cut direction each pass. I dont believe changing cut direction each depth will help with symmetry, in fact it'll make it worse if anything.
