Latest CC PRO features - 3D "Stock to leave"

For softer woods, I like to run two finishing passes - one at an angle to remove most of the material, then another with the grain to bring it right to size. In the past, I had to do this manually by lowering the Z between toolpaths.

CC 815 now has “Stock to Leave” for 3D finishing passes, and it worked great! It also allowed me to increase my DOC for the rough cut. Before, I would set the DOC to 1mm, so that the finish pass would have at most 1mm of material to remove. Of course, that increases cutting times! Instead, I can now cut more aggressively, and then use a ‘rough’ finish pass to remove the bulk so the finishing bit has less work.

So, the approach here is:

  • Rough cut, Stock to Leave (STL) 1mm, DOC 3mm. #201 (1/4")
  • ‘Rough’ finish pass - STL 1mm, large stepover #201 (1/4")
  • ‘Rough’ finish pass - STL 0.25mm, 15 deg cutting angle, 2mm TBN with relatively large stepover
  • Finish pass - 0 deg cutting angle, 2mm TBN with small stepover.

Final product had a few ‘whiskers’, but a nylon brush took care of that. No other finishing required.

Michael,that is brilliant I will try your technique over the weekend,did you cut all the finishing passes with the 201?

I used the #201 for the first two, then I switched to a 2mm TBN.

Thanks Michael,I should have read your description more closely.I have to carve some more collie dogs on the weekend so I will follow your process.Thanks

Looks awesome Michael, what made you decide on 15 deg cutting angle, or did you just pick any angle?

Pretty much ‘any angle’. It’s mostly to help break up long stringy pieces that can occur when going along the grain. I also thought that the two different step-over values might cause slight, visible changes in the cutting of the final pass if they were parallel.
