Hi all,
I'm fairly new to GD& T and trying to wrap my head around measuring position tolerances. I understand how to measure the tolerance if given an x,y dimension but how would I check the position callout highlighted on this print clip? A is a threaded hole but for the sake of simplicity assume it's just a bore. No CMM, just standard tools. I've come a long way teaching myself the majority of mechanical inspection but true position is something I'm struggling with, have reached out to many an engineer and even machinists who can't seem to explain actually checking it. All the literature and videos I watch give examples of say a hole position tolerance, with x,y dimensions to the center. I understand that. It's when diameters are called out is when I get lost. Any help would be greatly appreciated!
