Re: %GRR <10% not possible. How to get approval by auditor?

Discussion has gone in wrong direction from beginning. There is something wrong with measuring method and that's the problem.

Everyone who wants to use signed PSW as evidence that someone working for customer accepted any nonconforming document in PPAP file, soon or later will get nonconformity from auditor. First, it is not game, "Find 10 differences in two pictures" and as long approver does not find our mess, it is OK. Second, approver usually is not an authorised customer representative, who has power to waive requirements stated by procedures, manuals, etc.

That's an auditor's view and reason of many nonconformities issued. Some suppliers are doing in on purpose, some not, but these are auditors who are forced to check whether customer's manuals procedures are followed. PSW approvers are paid to do it first, but they not.

As I said 3d machine is best, but if you know its limitation, you simply do not select it as measuring mean.
