Dimension Identification for Quality Measurement
Dimension Identification for Quality Measurement
(OP)
Hi,
With the introduction of CMMs we now have the option of having very detailed measurements of the manufactured parts. However considering a complex part with many sheets in the drawing package, the CMM measurement report becomes very complex. The report is like a book and it is really very difficult to identify which dimension in the drawing was measured.
I would like to know whether there is a standard or practice of giving some type of identification info on every dimension, so that the measurement report also uses the same IDs.
Best regards

Of course, if you have 2 '1.00+-.02' dimensions in the same grid then it falls down.
What is Engineering anyway: FAQ1088-1484: In layman terms, what is "engineering"?

Let's say, for example, that there are 8 holes with a positional tolerance at RFS which is number 38. Each hole should be given a letter such as 38A, 38B, etc. In that manner, we can reflect the actual positional tolerance of each of the 8 holes.

I always wondering why someone try to invent strange new approach.
Design represent by drawing but fabrication by processes
Inspection is part of manufacturing process.
inspection document should be separate from component drawing.
It can be looks like or copy of drawing even but do not incorporate all info into design drawing.

Creating separate documents (copies of drawings or otherwise) can be a bureaucratic nightmare. I say this from experience.

Within a year or two ASME Y14.45 should be released. Its title will be something like "Measurement Data Reporting Practices". This standard will use, but not mandate, a tolerance numbering method.
Whether these numbers are applied to the design drawing or a separate inspection drawing will depend upon the organization's preference. Some can't abide by inspection information on a design drawing while others can't abide by maintaining an additional drawing. In my opinion it should be considered a concurrent engineering drawing which is a one-stop source of all the needed information.
