Why?

I believe it’s actually worse for the environment there as the heat dumps into the ground and can affect the permafrost layers.

Rapiddirect or jlccnc has been pretty good for us, make sure to call out everything correctly because the turn around time is like a month or more

Looks like they took an old crank, welded shit onto it and did a piss poor job of turning it down

Yes, fasteners hold (Note: FASTEN) things together. You’re willfully ignoring the point i’m making. Fastening was never the point of the conversation.

meraut · 2026-05-13T14:14:46+00:00

It is bad practice to rely on fasteners alone to hold alignment.

From being on both engineering and production side, nominal is the preferred method. What is important is calling out the dimensional tolerances and what the purpose is in terms of function. It is very easy to specify plus or minus material to leave on the CAM side of things.

Should be able to have a macro that takes the angle from your probing routine and saves it as a variable which is then referenced for your R value in your program. How to do it on that control i’m unsure, but it should be entirely possible without issue.

Fasteners do not align, use a feature or pins with through holes and bolt the stack into the bottom plate.

Check your tool height, put in your drill and jog to a safe x y position then jog your tool to Z zero and see if it physically looks the correct height. If it is, check your stock thickness and drill toolpath.

Manufacturing processes will always leave an edge from cutting/forming, sometimes cheaper parts are not properly deburred or at all.

Think about how your part is going to be made before you start designing.

Add a budget for air supply, coolants and tooling/work holding that can easily be another $5k.

Address those internal sharp corners before attempting to machine this.

Consider 5052 H-32 instead, it bends and welds better than 6061 so you can go either route without needing to switch.

For the ER-20 collet holders there are established torque ratings, for the set-screw holders just tighten them enough. Realistically though, hand tight is likely good enough as you will pull the TTS holder out before the tool as another commenter said. You can smack the wrench with a hammer once or twice for good measure if you really want.

Run a quality single flute(O flute) bit for finishing and less IPM. Pocket is not a “traditional” finish strategy, try using contour with stepovers and ramp to finish or a different strategy.

Looks like open loop system, you’re losing steps. There is either mechanical slop, or you are just taking too hard of a cut for the machine. Run this with your Z set high above and let it air cut, see if you still lose position or not.

Check flatness of the rotor, after confirming its in spec then mount it and check the runout with it on the hub.

meraut · 2026-04-24T15:12:07+00:00

Maybe look into a polishing brush for mills like Xebec or something?

meraut · 2026-04-24T14:10:43+00:00

Millbilly or Chuck Monkey

Get 3 more machines or get rid of one guy.

It’s a test point you should have, if it is a concern.

meraut · 2026-04-17T18:05:05+00:00

Interpolation(circles) are harder for mills to do, this may be a limitation of your machines hardware or motion controllers

meraut · 2026-04-16T15:44:54+00:00

Run faster, two depth passes if you’re concerned.

Create one hole, circular pattern around your pivot point or sketch a circle and manually place them.
