I really appreciate the insight to everything you sight. You make some good points. It changes a lot of things when you aren't sell machined parts vs selling a finished assembled product.Not necessarily. I run many different materials, so tool pressure in nylon will generate a different dimension than in stainless or titanium. I might have to tweak it a few thou to get it running where it needs to be. Once things are up and running, my offsets are changed while parts are running. There's no downtime involved. My boss doesn't see what I do as risky because he knows I think it through before inputting numbers.
The parts I make are strictly for the products my employer assembles and sells. We do work in a job-shop environment because we run the jobs that either outside vendors couldn't complete in time or just refused to quote at all, but nothing we make is for other companies. Every part I make becomes part of an assembly, where tolerance stack up can create problems down the road. I deal with tolerances much tighter than the +/-.003" I wrote earlier, like +0/-.001 in plastics that will change in size with the humidity of the day. That has me planning on how to reliably hold +/-.0002" so the parts will still be in tolerance tomorrow or next week. These hoops I jump through make it easier for me to quickly hold tight tolerances in stable materials. I'm not known for blowing my own horn, but I am one of if not the fastest producers in the shop.
With the tight tolerance plastics can you change the size a measurable amount on say 1/2 diameter x 1" OAL in 30-60 seconds by holding it in your hand?
