Re: Plug Gauge design
Please help if you can, I’m sure you might have argued over the “right gage pin method use” not the 10% product tolerance rule. The question is there a standardized method for pin gages on “how to use them”. I have found old reference material from MIL-STD-120.
George;

I am a bit confused by your question, so I may state the obvious and just remove these topics from the conversation.

You are not talking about:
Gage Size (how the gage size is determined)
Gage Tolerance (which gage tolerance paradigm is selected)
Gage Function (I assume you are speaking specifically about GO/NOGO functions)
MIL-STD-120 seems to deal with basic data related to the various styles of gages, including plain plug gages, but not how to use them. The standard is 216 pages long;

which paragraph has gotten your attention?
What you are asking about is:
How do you use the gage?
How much force is needed to insert a GO gage?
How far should a NOGO enter?
Should you twist it to make it go in?
Should a Diamond Style NOGO be used?
How often should a gage be used?
How many parts in a lot need to be checked?
Is there a published procedure for using a plain plug gage?

Are these the type of question you have?
Can you be more specific as to your exact question?
