We are definitely getting chips, not dust, and no burning on the boxes that I can see either. We have been using 1/4" x 1" CEL x 1/4" SK x 2 1/2" OL (75-102 by freud) solid carbide 2 flute upcut finishing bit. The one exception was the few cuts I ran yesterday with the 75-025 solide carbide 1 polish...

Thank you! I am excited about the design if only I can make it work consistently. We eliminated the tear out with faster feed rate and wider walls, which felt like progress, but now I am having bits break in the final profile cut-out stage. I'm a little worried about tearing out those sidewalls agai...

boxpoplar2-2.jpg Another picture of the above box. Determined that maybe some of the walls were simply too thin, so I reworked my file to make them just slightly thicker and more even all around. boxpoplar3.jpg Had success with this one, felt good about how it ran and what it looked like...so I wen...

boxpoplar1-1.jpg boxpoplar1-2.jpg Switched to poplar to try some different settings, because we had trouble with poplar doing the same thing on a previous iteration so hoped solving it on the poplar would be a good step and it's cheaper. The first one was awful, with a lot of issues on that top wal...

Update: played with the settings some more and made the most problematic walls just a tiny bit wider, and finally got a cut without any blowout on the practice board (poplar, which we'd had issues with blowout on that file a lot). Bit the bullet and put in a brand new bit and ran the file on the pur...

I just cant figure out why my pocket walls are tearing out, we have increased speed and decreased speed, changed stepover and wood species, nothing seems to help also tried new bits we are trying to carve dice boxes, we have increased the wall thickness as well, just pulling my hair out in Indianapo...
