This series of articles on geometric dimension and control will help you in the. the datum plane, datum line, and datum point, as examples. GD is trading within a range we consider fairly valued. Profile of a surface describes a 3-Dimensional tolerance zone around a surface, usually which is an advanced curve or shape. Coaxiality, which is a regulation on the accuracy of the central axes, is measured using a dial gauge or a coordinate measuring machine. The 3-2-1 rule says: – The primary datum feature has at least 3 points of contact with its datum plane. Composite tolerances are used when we have relatively looser location requirements but tighter orientation tolerances. Bonus tolerance explained: As the size of the pin departs from MMC toward LMC, a bonus tolerance is added equal to the amount of that departure. The first page is a summary of all the geometric control symbols that shows graphically how they apply: to surfaces or to features of size. ET.
