3D Contour Tool path

3 posts in this topic

Had to switch from a 3D Contour path to a Surface finish project Tpath because the ball mill I used didn't follow the surface at bottom of cut. I couldn't figure out why but I had to go with what works so I switched to the surface projected path.

 

The geometry I chained for the 3D Contour was projected onto a compound angle. You could also see the variation in the Z depth by dynamically rotating the part looking underneath with the part shaded. Of coarse I scraped a part before I noticed.

 

Could this be because for the 3D contour to work correctly I needed to chain geometry at the center of the tool and not the edge? Or is this a bug. It was a 3D path because the ball mill was cutting an island and there was a compound surface at the bottom.

 

I'm running X4

Thank you all

Yes. You must drive the center of the ball on the 3D contour

 

 

Ah ha, the answer arrives. I may have known that a long time ago, don't know for sure but I can tell ya

your reply is greatly appreciated. Thank you.

 

It would have been a lot of work offsetting all those tiny splines. This geometry came from Key creator then from Surf cam, then to me in MCam. Doing a pocket with the original geo. then projecting it would have been the quickest way for me in this case I believe especially if I had to lie about the cutter size to get the correct size slots etc...
