PPAP Manual 1.2.2.7 Dimension Result Report and Tracking Samples

Dimension result report

I have a question about the dimension result in PPAP manual 1.2.2.7.
This is the way we are doing now: QA pick two samples from PSW finished parts after they were sent to us. We measure all the dimensions on drawing. But how about the dimension we can not measure from finished parts. For example: The drawing have a length spec before bending and after bending a pipe. These two dimention are all on drawing. How can we measure the length before bending from finished parts? Also some dimension on drawing is just for process control? After finished, These dimension are covered by other component. We cannot see them.
If we have to take all the dimension, We have to follow those two parts from the beginning to the end of process? Does it sound a little funny?

Anybody can shed aome light on me? Thanks.

In my experience, the answer is YES. 100% dimensional layout means just that. I guess you COULD "back engineer" with the thing that if all the bends and distances between bends are to print, the O/A length must have been OK, but that doesn't sit right with me.

If, in fact, they are for Process Control, you are probably monitoring them (?)and should already have measurements from upstream in your process. Just transfer those to the dimensional results sheets. Otherwise, you would need to "birddog" the parts through your process and take measurements at appropriate steps so that you CAN measure those "hidden" features.

We have a couple of parts that have multiple part drawings with different customer part numbers. We PPAP to each drawing even though the customer only buys the "highest order" part. Just a fact of life we deal with for certain customers. Yes it can be a pain, but......... que sera.

So I can just elaborate those particular samples for customer.
I thought we were supposed to pick samples radomly from finished parts so samples can represent whole the lot quality. This is where my confuse from.
I take dimension for some SPC process study if they are SC.
What is the real purpose to these samples and that report? Help me to think it through. Thanks

I guess my answer would be derived (quoted?) from the PPAP manual - "The supplier shall provide evidence that dimensional verifications required by the design record and the Control Plan have been completed and the results indicate compliance with specified requirements." It states further that you need results at each "unique manufacturing process." That seems pretty straightforward to me.

As a "side bar" - More than once we have been "saved" by the dimensional results sheets and proving compliance to specifications when a Design Engineer has performed a stack-up analysis incorrectly.

Hope that helps.
