I think this may be allowed per this standard by a couple different explicitly defined methods, one of which "rounds to values nearest each limit" (meaning that even in the most "unfavorable cases" the two original limits will be changed by no more than a small percentage), and another ...

The intended meaning of the .001 TIR callout may be concentricity (high school or Y14.5 '94), Total Runout, or Circular Runout (which didn't come into the standard until 1966). Keep in mind though that Y14.5M-1994, 5.12 Concentricity, specifies that "Concentricity is that condition wher...
This table is used to define the parameters of the individual resulting dimensions (closed components) of the dimensional chain. One line of the table belongs to each dimension. The meaning of the table is obvious from the following description: ...

Critical dimensions in the automotive field relate to dimensions where there is a statistical control required and it became a game in the past. We had charts all over the place with many having no meaning whatsoever. It is a bit better now but some Customers still plaster their drawings with...
If I misinterpret your meaning, than please disregard this reply. To everyone else, thanks for the replies! You've given me plenty to think about. I ask these questions, not only for my benefit, but because usually I've got to convince my supervisor to follow a particular method that ...
But it does not state in Annex (A) what the meaning is for "Broken Edges". I am still unclear as to what ISO 2768 means by "Broken Edges". yes...It states "External Radii and Chamfer heights for broken edges" Does the stamping process have broken edges ? I am trying to establish...
The whole point of a standard like Y14.5M-1994 is that it defines the meaning of everything you apply to your drawing. Even if you do not use GD&T symbols, the standard explains how your +/- dimensions are to be interpreted. A basic assumption about fabrication drawings is that you ...
