Radial toolpath as a "fan"

[CarbonCAD]

I have a graphite part that has 3.5 dia. x .002 dp concave and the radial toolpath has worked the best. Being that it is graphite the tool wears a lot, so when the tool gets back around to where it started there is mismatch. Is there a way to work from both edges and machine the concave with the tool mating up on the same spot 180 from where it started? See sketch.

2 paths with containment?

Not that I'm aware of, but maybe someone has a trick.

what about spirling in from the out side. tool wear would be on the shape not a mismatch.

just thinking?

 

Ken,

This is what I was talking about. Seems to be what you asked for.

I don't know if this is what you meant, but here is an idea.

If I can't get a tool path to do what I want I draw a custom tool path and project it onto the surface using a surface finish project tool path. Using this tool path you can get some pretty good results. I modified the previous MCX file for an example. This tool path would have no mis-match.

I see manuel beat me to it =)

They look really good using the manual method, and it does what I need it to. I'll give it a try. Thanks.
