[Ri...] Posted May 21 Share Posted May 21 I do not have a copy of ASME 1y14.5 to search, I am looking for what describes how shown dimeters above a True Position (TP) are to be handled. See example image. At the left side, there is a note (12) that declares adjacent diameters are to be applied to the TP. at the upper right, there is no Note12. It is being said the diameter above the TP is related to the TP only and the diameters above fall into the the foot notes in the title block, which is "Runout .005 FIM". This makes sense with the Note12 declaration. Any help on this is appreciated.Capture.PNG Link to comment Share on other sites More sharing options...
[Pe...] Posted May 21 Share Posted May 21 ASME Y14.5-1994 5.7 COUNTERBORED HOLES Where positional tolerances are used to locate coaxial features, such as counterbored holes, the following practices apply. (a) Where the same positional tolerance is used to locate both holes and counterbores, a single feature control frame is placed under the callouts specifying hole and counterbore requirements. See Fig. 5-37. Identical diameter tolerance zones for hole and counterbore are coaxially located at true position relative to the specified datums. (b) Where different positional tolerances are used to locate holes and counterbores (relative to common datum features), two feature control frames are used. One feature control frame is placed under the callout specifying hole requirements and the other under the callout specifying counterbore requirements. See Fig. 5-38. Different diameter tolerance zones for hole and counterbore are coaxially located at true position relative to the specified datums. (c) Where positional tolerances are used to locate holes and to control individual counterbore-to-hole relationships (relative to different datum features), two feature control frames are used as in (b) above. In addition, a note is placed under the datum feature symbol for the hole and under the feature control frame for the counterbore, indicating the number of places each applies on an individual basis. See Fig.5-39. Link to comment Share on other sites More sharing options...
