Default storage boxes in exchange for knowledge

Greetings
I am loving my new Camaster. The horsepower, frame, gantry strength and rigidity.
3 years of lower quality machines has left its mark.

I needed some storage boxes. So my solution was to cut strips 9 7/8 wide by 30 put them on the cnc and machine the box joints, dadoes, and handle. one front/back and side per sheet. Plywood was 60x60. So set up a register board. I used 1/4 ply (with screws every 10 inches or so) move the bit into the material a little bit (just don't hit the screws). run fence file. you now have an edge square with your machine. and a start point. after the first run I move the plywood a little forward so it is machined. to cancel out any out of square in the plywood. There is one Tab for the handle right where it finishes cutting. Ramp %20. No tabs on the box joint waste as they would pop out anyways. The last set of box joints you get some pieces flying but nothing to jam anything. suppose you could add tabs there.

Cutting at .25 depth 16,000 rpm carbide upcut 170ipm for the box joints and 120 for the dadoes. I highly doubt I get any where near that speed.

I have attached the cut file feel free to use.
It is set for 12mm baltic birch which is .468 inches. at least my sheets were.

I have cut 6.5 boxes (13 panels cut) and the bit is starting to get a little dull.
So what would you change? Is that longevity to be expected.

Follow all safety rules, and common sense. This file is from a person on the internet. what might be fine for me might not be cool with you. I am not liable for running this file or how the end product is or was used, including any damages, or injuries. I doubt any of that means anything but sure sounds good. Lol and Hey Happy New Year.

here is a small one. cut from 6mm which was a little less baltic birch
they are higher in the back so you can have several in a drawer but be able to lift them up.... Maybe I should sell these plans? nah who has time to make extra money.

Set up for your machine, I used 1/8 bit but your machine your bits your rules.

Thank you James. I have been using G wizard to try and help me out.
I know you guys can cut faster due to the higher horse power. Before i was limited to 24,000 rpm and max of 118 ipm bits did not last long at all had to take shallow passes due to the low HP. I have made 7 boxes so far and the bit shows no heat build up and still going strong. with is way way beyond my previous bit lifespans.

Well I am down to 12,000 the chips are getting a little larger less tearout during the dado cut. how ever fit is a little to tight. so might have to add a final pass just to smooth it out.
