Hi there. I'm new to these forums, so forgive me if this topic has been covered (I'm sure it has). I drew up this CAD drawing for some parts that I'm working on at work. As you can see in the drawing, the general tolerance is +/-. 03. I forgot to include that the small diameters of this part are . 6246-.624 and is supposed to hold a true position of . 004 to datum A at MMC. Datum A is the centerline of the inside diameter. My question is, how much bonus tolerance would I get on the . 750 diameter? The inspector at my shop is trying to tell me that I don't get any, but I know that I recently learned in school that with an outside diameter, you accrue a bonus tolerance if the diameter were to decrease as opposed to a hole or something. Thanks for all and any input! And merry Christmas!
