Wall thickness is depicted on the ANSI/ASME B18.3 as item G and Key Engagement as item T Please look at this to see a picture depicting what I am discussing below.
Both Items are located off of the same line, what is the best way to measure G?
Our customer is measuring it very differently than us, we have tried to measure it their way (however the method is flawed in our opinion). Does anyone on here have to measure this item, and if so, how do you go about it?
We currently use a hex gage member to verify wall thickness. We zero out the caliper on the hex gage length, insert the gage into the part and measure the parts head height and our hex gage length as an assembly, the reading is wall thickness per this standard.
Our customer zero’s the caliper while measuring the head height, then using the Depth Probe of the caliper tries to insert it along the edge of the hex, bottoming out the main scale against the top of the head and the resulting reading is their wall thickness measurement (way too much variation and not reliably located where the standard details)
Any help in providing evidence to validate either technique (ideas, useful links, etc) would be appreciated,
Thanks,
