At my company our main customer often sends us very difficult parts to make the tooling for then we have to run them.
CASE #1:
The customer usually sends us preliminary information that is vague at best. The part starts out looking simple and by the time we are kicking off the tools the part has changed into something barely feasible. Yes, we keep quoting as we go but something else to consider is that we very rarely (I can not recall once) have completed prints. Usually when we get to PPAP the "release" prints are missing the C Datum completely, they have line tolerancing to intersection points of lines in addition to profile tolerancing (which by the way are very difficult to get to measure in tolerance when combined). After we get these new prints which resemble little of what the customer and our company have been discussing we have a clean up meeting where we are asked to draw up with justification the changes we require (SREA) to the print. And submit the PPAP to the print mark-up. Several months later the print is released and updated to the SREA except it does not match what we asked for or submitted. This causes our next PPAP to have dimentional issues as a result.
( no they do not make us resubmit at print release just update warrant and yes we bring up the print issues )
CASE#2:
Lately the customer has been sending us prints during APQP and having us tolerance and datum them. We are not design responsible nor do we have access to the assembly prints or CAD that our parts mate to so we basically pull numbers out of our chutes and through darts at a chart until we get them all figured to what we think we can reasonably hold. Then the customer dimensions the print completely different anyway and we end up with case #1.
Do any of you know a way to stop this madness? I am wore out.
Oh, by the way we just got another job from them and their QM dropped of a PSO book which was not known to be a requirement until a month after the job was awarded. We have never done PSO but it looks like some work.
