Surface Finish Blend stray toolpath x7"

 

Hi,

Surface Finish Blend is one of my favorite toolpaths. I feel I understand it well, but sometimes these stray wall climbing paths form. They don't actually touch the surface but are out in space. Takes me a lot of tweaking to get rid of them sometimes. I start with simple setting; .002 or .005 Total Tolerance/ .01 Step, Zig zag, Gap is 800 and No Arc Filtering on a 3/8 Ball  milling .270 typ fillets.

 

Anyone have an answer to this?

 

 

 

 

Thank you

To me it looks like a gap move. The tool is repostioning itself between cutting moves (which is considered a "gap").  You will  get some sort of reposition move at the edges, looks like you have "follow surface" and a large gap value in there. A smaller value and the tool will retract or something. Sorry don't have a real answer though, just an explanation.

 

Yes it's an awesome path though.
