Where do I sign up for my free samples?

I think I'll take one of each.

Were these cut on an Omax?

This has to be the third or fourth post I've seen you ask this... Just curious, why?

Our waterjetting is done on an Omax (to save you time when we eventually post pics :rolleyes: )

You guys are lucky. We're cutting ours on a CNC router, and it's taking quite a while. We're looking at about 4-5 hours for a diamond pattern baseplate.

Odd.

We have a pretty intricate design and it only took 35 minutes on our router. And that was me being super lazy. Could prolly get it faster.

We did a similar BP to what we've done the past few years.

We gave the freshman brand new files this year.

What is your material and thickness, cutter type, spindle speed feedrate, and stepover?

We are running 1/8" thick 6061-T6 plate with a 1/4" 3-flute ZrN coated variable helix endmill, 16,0000 RPM, 30 IPM, 35% stepover, dry cutting, and it's cutting nicely. We tried pushing it faster and did not have favorable results. Also, our router is only a 2.5 HP machine. Also, we're turning all the pockets to chips. No solid pieces left behind.

Seems to be an Omax Intern.

These parts look super sweet, cannot wait to see them all powdered/ano'd.

There's your problem. I would contour, not pocket.

Ditto,

What Cory said, we don't pocket. Its a waste of a time, we also use a mister.

Omax is one of our sponsors.. We like to see other teams using the product.
In our new school, which will open next year...we will have our own OMAX waterjet..

Navid was an intern for OMAX but now works for them.

good luck

We're pocketing because we didn't want the loose pieces getting grabbed and flung.

Right,

We've dealt with that by using double sided tape (especiallly if your running dry, we run wet so its hard) and by just making sure we have enough clearance between the holder and the material so when the piece does get flung it doesn't get caught.

For us the tradeoff of 5 hours vs 35 minutes is pretty huge. So we just have a kid sit there and make sure everything is g2g.

A vacuum table should hold it down well, but most routers don't have one.
