The (2) .119 diameters on the attached dwg are raised bosses. The .226 diameter is a hole. Datum A is the common planar surface these features are normal to. What we are trying to accomplish with the GD&T is first hold the 2 bosses center to center dim to .000 TP if at MMC with bonus tolerance...
I have an application of profile tolerancing on a gage. There is a cavity in the gage where portions of the inside profile are very critical, and the remainder much less so. In the attached dwg, the portions designated y-z and w-x are the critical areas held to .0004 profile. The remainder is...
We have a question of expression/interpretation. In the attached sketch, the primary datum is a contoured surface -this is not new for us as we have worked with this many times before. The contour is defined by the baic dimensions and the profile tolerance. The (2) .437 dia holes are located in...
I haven't seen this appear on a dwg in a while, but I know from previous experience there is a way to describe the maximum amount of measured T.I.R. in a given length. For instance: | // | .002 (per inch) | A |, meaning the measured feature must be parallel to datum surface A within .002" per...
