Multi-axis contour

Maybe someone can explain why the tool path refuses to follow the assigned contour?  It will produce on the convex arcs but not the concave sections.  Maybe I'm trying to produce this tool path out of the normal process?


Any insight would be helpful!

Hi Seth,


I've attached the file to this reply. I'm sure I'm trying to make this operation do something it wasn't intended to.  However, I couldn't get the swarf function to select guide paths properly and resorted to what gave the best result so far.  I modified the model from a vendor supplied file to create this latest revision.  There could be something wrong with it as well.  


Thank you for your attention to this.

Hi @rstoddard9MQBB,


Multi-axis toolpath tries to touch selected curve but it's not possible inside these concave sections without gouging more than tolerance so some cutting paths are trimmed away. It's possible to avoid this by increasing tolerance but you'll get small gouges against bottom surface.

I've made the following:

1) Reduced "Surface triangulation tolerance" to get better surface normals and more smooth toolpath as result.


2) Increased tolerance


Toolpath isn't trimmed but it has gouges (in tolerance) against bottom surface.

I did expect the gouges due to the way that it is.  This has helped tremendously.  Thank you so much!
