It uses a symbolic language on engineering drawings and computer-generated three-dimensional solid models that explicitly describe nominal geometry and its allowable variation. It tells the manufacturing staff and machines what degree of accuracy and precision is needed on each controlled feature of the part. This article is based on that standard, but other standards, such as those from the International Organization for Standardization ISO , may vary slightly. The Y The ISO standards, in comparison, typically only address a single topic at a time. There are separate standards that provide the details for each of the major symbols and topics below e.
There are two main standards for Geometric Dimensioning and Tolerancing in use today. American National Standards Institute Group of industry professionals that thought it would be good to standardize the civilian manufacturing as well. ANSI Y Presents the design practices for dimensioning and tolerancing of gages and fixtures used for the verification of Maximum Material Condition MMC size envelopes and Virtual Condition boundaries generated by Geometric Tolerances controlled at Maximum Material Condition.

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. The second is a more conventional reference guide that has a lot of useful information about each control symbol, now updated for the standard and includes several useful acronyms.

ASME Y In today's modern and technically advanced design, engineering and manufacturing world, effective communication is required to ensure the design and manufacture of successful products. A datum is just a fancy word for saying which specific feature on a part will be used as a reference zero for tolerance calculations, dimensional measurement, and most importantly, from where the feature s manufacturing should build from to ensure a consistent part. Without the use of a datum system zero reference on a part, it is not clear to manufacturing or quality where to manufacture or measure from.

Tec-Ease, Inc. The rules of geometric dimensioning and tolerancing have changed over the years. In addition, the meaning of such symbols as runout, total runout, concentricity and symmetry have changed. You cannot go by the drawing date since many companies may delay adoption of a new revision for several years. Often you can determine which Standard was used by observing differences in the callouts. Your choices of Y
