Hi Everyone,
This is my first post to Elsmar Cove.
I am a dimensional metrologist at a plastic injection molding company that makes quite a bit of automotive related plastic parts. Some of these parts are inspected by a production gage that checks the outer profile, or silhouette, all the way around the part. These "drop gages" are essentially go, no-go gages that verify that the parts haven't exceeded a maximum or least material boundary specified by a profile tolerance on the part drawing. Please review the inserted images. As you can see, these gages were machined out of aluminum. A quality inspector would simply attempt to place the part in each of the machined aluminum pockets. The part is required to fit into the larger oversized pockets, and resist fitting into the smaller undersized ones.
A large number of gages of this style were created and provided to us by our customer and I have been tasked with inspecting them. Unfortunately, there is no CAD information available that describes the shape of the various profiles that were used to CNC these shapes. Hence, there is no reference standard by which I can verify these gages. What is our company's responsibility in this context? I am not particularly well versed in ISO standards, but I have been told by my colleagues that we must inspect these gages to remain ISO compliant. However, without our client's assistance, I don't see what we could meaningfully check on these items. Would a simple periodic visual inspection for dents, nicks, etc suffice?
