Realized I was clamping parts too tight for 5 years after a senior guy watched me once
Was setting up a part in the vise on a Haas VF-2 at the shop last Tuesday. Old timer Bill walked by, said "you're choking the hell out of that thing." Told me to back off the torque by half. Tried it. Parts stopped coming out .002 oversized. Never once thought I was warping the material by cranking down so hard. Anyone else learn a basic setup trick way later than you should have?

Why are we acting like clamping harder is ALWAYS a bad thing? I've been doing this 20 years and sometimes you NEED that extra squeeze to keep thin wall stuff from chattering. If your parts are coming out .002 oversized, maybe your tooling is dull or your speeds are off, not the vise pressure. I clamp the hell out of stainless all the time and never get warpage because I check my setup with a test indicator before every cut.

Hell yeah, @williamd70 is right on one thing, but honestly most guys I've seen crush parts and wonder why their tolerances walk. I've learned the hard way too many times that lighter clamping and checking your indicator before every cut beats brute force any day.
