I agree that we should check the correct way but, I cannot find any documents that say we can't check backwards.
This issue keeps coming up here. I do print checking here and we issue in-process sketches where we show the location surface and what to machine at this step. I just got into an...
Item 1. You are correct, it is not the correct way to check it and that is what creates the checking problem. I have seen a lot of inspectors check backwards and assume there is a one-to-one conversions of tolerance. Unless to the tolerance is in degrees, perpendicular is not one-to-one when...
I recently recieved a messsage from QC about a perpendicular check they were having trouble with.
This turns out to be an ASME Y14.5 issue. The print pointed to the threads and said perpendicular to a datum face within .0005 (in geometric block form). Our inspection has a Johnson gage locator...
