Attribute gage in stamping press as poke yoke

We recently have begun putting an attribute checking gage in our stamping press. If the part is undersize , the part is diverted to the reject chute.
My question is , I am trying to verify that this gage will do what it says it will. They are checking it with a defective part at the start of the shift. I have asked them to define with parameters the piece checked. The dimension is .449 min and .446 max diameter. Tight now, they are saying the tool or gage is doing its job if it catches an undersize part. They are not concerned over an oversize part. Also, we spoke about if there is a need for claibrating this device. The tool is tapered . Has anyone gotten into this type of poke yoke? How do you do a Gage R&R on such a device.

Is the gage manual? Does the operator have to use that gage to make a decision? If so, this would not be a poka yoke in the usual sense. At best, a very weak poka yoke.

If this is an automatic device that automatically diverts the bad part, it would be a strong poka yoke.

Poka yokes need to be checked with a known bad master part frequently. Looks like that is what you are doing. This master needs to be calibrated/verified.

Do you have the AIAG MSA manual? It completely explains how to do GR&R on such a device. Also search the Cove for attribute gage studies.

Good luck, hope this helps. Please ask for more specific help if needed.
