End Grain Tearout Help

1

Hi All,

I have a bunch of pieces of a mahogany that are 7.75" wide and between 1.75 and 2" thick that I need to cut the sawtooth detail out of one end. In the first three I did I used a simple profile tool path. That was quick, but I did get some tear out when the bit exited some of the teeth. Does anybody have any suggestions of more clever ways I can set this up so the cuts are cleaner? I use Rhino3D for my CAD work and have VCarve Pro mostly for CAM. I don’t have any experience with Fusion 360 but from what I’ve read Fusion sometimes has better tool path solutions.

Thanks in Advance,
Garth

I had a similar problem with some custom moldings I was making. One corner always chipped out. So I changed the CAM to cut the end grain side of that corner first - I mean, even before roughing. It would dig a hole down into the wood, make one finish pass across where the one edge would be, then move on to the next problem corner. Then do everything else. Thus, when it got to that corner in the normal flow of things, the cut that would have chipped it had already been done, and fully supported at the time. Every corner came out perfect.
