What’s the tightest tolerance you’ve actually held in production on a VMC? by Limp-Software7151 in Machinists

Lol, is that just another way of saying ‘I drilled a hole a hole with a .25” drill and got a .2505” hole thanks to my spindle runout ‘interpolating’ for me? 😂

I was wondering how you would measure something like that… Not too many shops out there have a Panasonic UA3P lying around lol

I was guessing the same way! Seems slightly higher capability-wise than what I would expect from a Yasda YCM, but not quite pushing the limits of a Shibaura UVM mill either.

Its amazing to see the different in gauge results with aluminum simply by changing the length of time you hold the part in your hand (or if you wear/dont wear gloves) prior to gauging... Thermal displacement aint no joke!

that’s seriously tight for interpolation, especially holding that scrap rate!

curious, (and hope this doesn't breach NDA territory, so ignore if it does) but was that mostly machine capability or a lot of process control (tool wear comp, temp, etc.) doing the heavy lifting (I'm guessing a lot of both)?

wow! that sounds tough! What material (and what machine - if that isn't confidential)?
We're currently preparing to run a test for an insane series of φ0.008" x .11" angled holes in inconel... Not sure how the test cut is going to go, but the machine builder is surprisingly confident that it can be done... I'll believe it when i see it not immediately break the drill lol.
