Hello everybody,
I work in a company that produce machined parts for various types of industry (automotive as well).
We bumped into following problem: Our new customer placed an order for part samples . Drawing was clear, all dimensions and specifications marked. GT according to ISO 2768mk. So we produced first samples. They were accepted and we started batch production for about 1000 pcs. Then the new types of parts were ordered again with sampling. Sampling approved, production started. This has repeated for about 5 types of different parts.
Now about a week ago (after about a half year of non problematic business) the claim arrived, that one of the part's dimension does not comply with the drawing. We found out - that there is reference in every drawing to customer's norm which we have not received. We clearly made a mistake by not noticing this reference which closely specified the hole tolerances (in this case H13).
So my questions are:
1) which side is in the right
2) how can we advocate ourselves
3) what is superior in general (drawing vs approved parts).
Thank you very much for your comments
