I have read a number of the posts on tape measures, but this is a slightly different twist. The plant where I'm at has long used tape measures ("we've always done it that way"). The problem is that most tape measures resolution is only at 1/32" or 1/16" and the tolerance ranges on what we are measuring are typically anywhere from +/- 0.016" to +/- 0.047"!! I have done several gage studies using various operators and not one has passed to date. They all fail based on the ndc, % study variation, % contribution and of course P/T ratio!!
Am I missing the boat or is this a pointless activity to measure with a tape measure? I have discussed this with my manager but the direction I got was to get a certified tape measure. I was then told to check this certified tape to other tapes to verify their accuracy. After that I was told to have the various operators check the same piece 10 times to make certain that they could accurately measure a piece with it.
This seems pointless. I still strongly believe that even though people "build houses with tapes" that they are not up to the task at hand.
Please advise if I am missing something from the outsiders point of view.
