Carving problem

[Jroberts71 (John david roberts)]

In an attempt to be brief:
1.3 inch thick board w/a .375 deep pocket. Carving 2 crabs and a small circle with a starting depth of .375 down to .467. The small circle is not a problem. The crabs however are showing an 81 minute carve time, these take 8 minutes each in any other advanced Vcarve operation. When you do the quick math it’s as though carbide create is regenerating the crab carve from a starting depth of zero to a final depth of .467 instead of a .375 starting depth down to .467. Finally if I input a starting point of zero down to .094 each grab takes 8 minutes. Picks included to see if I’m missing something

First, this is an estimate.

Second, the time probably includes lifting all the way out of the pocket during the toolpath.

Third, if you reduce the Safety/Retract Height in Job Setup you may be able to bring this down.

[Ed.E (Ed)]

Have you looked at it as two separate operations? First run the pocket to .375, reset Z zero in the pocket, then do the v-carve with a shallow retract height. When the v-carve is finished the Z should come all the way out of the pocket before the machine parks its self.

What Ed & Will said. Lower the retracts and use your 0.0 to 0.094 toolpath with the Z zero set at the bottom of the pocket. Just look at the simulation & make sure it won’t collide with the walls of the pocket, and start your tool above the pocket on the machine. It should retract before starting, but just to be safe…
