Given most of the total tolerances on dowell pin holes we do is .0005 inches, what do you use to measure them?
We're using deltronics pins (.0001 increments) which I'm pretty sure is what most people do.
Pactically, with these numbers am I dead before I even start? If we have any variation in measurement it is likley to be 1 pin or .0001 - that's already 20% of the spec before we start.
If this is the case, what is typically done? I'm guessing this would be one of those times you share results with the customer and come up with alternative solutions? I'm sure many of you in precision maching have already addressed this very typical scenario - please share your experiences!
I am interested in both keeping parts in spec and also process monitoring.
I did actually run this GR&R (see attached) but still thought the questions are fair ones to ask. Comments on my results appreciated too - still learning!!
