I completed a plaque as a gift to a new mother. The quick and dirty job came out nice, but the cut took quite a while. I decided to hone my optimizing skills by cutting the carve time and adding it to my generic box of stuff.
The original did a rough and finish toolpath to the vector at the edge of the plaque boundary (cut out line) as the 3D boundary. To optimize, I outlined the 3D toy blocks and banner and used that vector as the boundary for the new rough and finish cut of the 3D. Looks good. The flat section in the center of the toy blocks and banner is 0.4404" deep. I then set up a pocket toolpath between the outline vector and the plaque perimeter. It looks pretty good except that the depth is only 0.3096"!
I have to be missing something obvious...

Re: Toolpath not cutting to specified depth
Hi Gerry,
The top of your material is at Z=0.75, the pocket at Z=0.3096
0.75-0.3096=0.4404
Not too bad for a depth set at 0.4404

Re: Toolpath not cutting to specified depth
BTW, your clear toolpath with the 0.25 endmill is way too long. A stepover for a flat surface machined with an end mill doesn't need being so small (8%). Try something like 40%.

Re: Toolpath not cutting to specified depth
I knew it had to be a brain fart. I've got the math in the correct order now...
P.S. I was looking for a real smooth surface on the endmill. I'll try bumping it up.
tnx,
Gerry
