Yes, our control plans list the feature, drawing grid location, process spec/tolerance, measurement tool, sample size, sample frequency & the reaction plan for non-conforming goods. There is a control plan for every operation on every part.

The Help for this program was created in Windows Help format, which depends on a feature that isn't included in this version of Windows.

we have such work sheet too. but the QA inspector just did not understand the root radius is an added parameter in this case. is there a chart/manual saying, +/-.001, use caliper, +/-.0001 micrometer, internal corner radius, reprorubber green (the thinnest kind), ..... etc?
thanks.

At some point this surely needs to come down to training/experience/competence of the inspectors?

I.e. if they don't know how to do something, or see something different or... then they need to ask. This also means having someone to ask that can/will give/find the answer.

I have tought lots about threads but have never seen a J thread before. I just had to look it up. A large portion of our business is aerospace and I havent seen it. I guarentee not one of our inspectors would have caught that. Unless they deal with them once or twice they would never have picked this out. This is why I personally review every print to make sure that our inspection staff has what it needs or to add notes to the inspection folders. Personally I feel like this was the responsibility of engineering to point this out if it is out of the "norm" for your company and could easily be overlooked. If J threads are used very often there then the responsibility is back on the operator.
