I just spent 2 days working on a special gear blank.
The customer had been to many other shops with this job, and no one could make the part correctly (in spec). They wanted 12, and I agreed with my boss, that I'd make one part complete (in 2 ops) to ensure my process would work. Well, I finished it, and it was dead on top limit, but it was in spec, according to the multiple cmm checks I did on it...(with report print-outs for proof). The thing is, I'm dead sure that over the next day or two, it'll move. It may move in a good direction, or a bad one as the part relaxes.
My point is, with parts that require this level of skill and attention to make properly, and QC departments on the other end, that can spot a freckle on a mosquito, I don't think we're ALL in danger of losing our work to semi-skilled workers...
