V-Inlay (Zank) with 30 degree bit - Time Estimate Issue
I running some tests using a new 30 degree Amana bit but I'm confused by the run time and am looking for any advice. Screenshots of the new tool and run time estimates are attached.
I'm travelling 8mm deep (0.314 inches) and doing it in 4 passes of 2mm each as suggested by a tutorial I'm following and the specs from Amana for the bit. Am also using a 1/8" clearance bit. The working area is only 8"x x 5"y.
The time estimate in Aspire is 63 hours per pass and there are 4 passes????? A recent actual test with a somewhat similar bit that I based on a Chip Load calculator was still 6 hours per pass for a total 24 hours for the Male Pocket piece but I was having lots of tear-out so I got this new 30 degree Amana bit and used the specs provided by them.
Are there any improvements I can make to this 30 degree bit to improve the time estimate as this is unreasonable.
Thanks.

Your pass depth for the tool is set to 3 thousandths of an inch. It would be doing over 100 passes to cut 0.314".

Thanks Adrian. Is the value provided by the Amana tool database I downloaded. I just removed a zero, from 0.0031 to 0.031, and the time estimates are far more realistic now. Down to 2 hours per pass.

Yes...sort of. I said "4 passes" but I meant 4 separate toolpaths at 2mm each. So I'm going for 4 toolpaths of 2mm each for a total of 8mm deep. So at 0.031 (about 1mm) it'll do each toolpath twice. It seems to be working okay. Much faster...about 2 hours per toolpath and very, very little breakage.
Thanks.
Thanks.

Okay...several tests later and now I've got it!!! Thanks everyone.
Here's a new cutting board with inlays of a Musical Scale. It was supposed to be a maple board, cherry scale, then walnut notes but I was short on maple. To compensate, I used walnut for both the board and the notes but I put the grain of the notes at 90 degrees so it would show better.
Oil-wax finish and I'm very pleased with the results.

Very nice cutting board, wood selection I think was right on.
I think turning the grain on the notes was an excellent idea
and gives a nice flow to your cutting board.

Thanks all. Looking forward to making more cool designs...but Mrs. says we already have too many. LOL...what does she know (she's not listening is she?).

Very Nice Work
Re: V-Inlay (Zank) with 30 degree bit - Time Estimate Issue
Noticed you have the bit loaded as an engraving bit. The stepover is calculated on the "Flat Diameter (F)".
You can increase your stepover to 90%+ and get a clean cut.
A "V-bit" assumes a pin point (which they normally aren't). The stepover is calculated on the diameter of the bit.
