tolerances are specified, and each symbol has a clearly defined meaning. Symbols take less time to apply on a drawing than would be required to state the same requirements with words. The symbols also require considerably less space. See Figure 1. Figure 1. Equivalent Symbol and Note 1.2 The symbols are presented in two groups for easier use of this section as a reference.

Geometrical Dimensioning & Tolerancing (GD&T)

Linear Tolerances – Limits & Fits must be communicated on the drawings. When dimensioning a part drawing, linear tolerances are used on the functional features of the part to specify the tolerances that are allowable. General Tolerances: In precision engineering, dimensions which only show the nominal size are controlled by a general tolerance. This will normally apply to non-functional

How to determine tolerance and what tolerances are

TOLERANCE :Tolerance is the allowable variation for any given size in order to achieve a proper function. Tolerance equals the difference between lower and upper limit dimensions. Example; for 0.500-0.506 inch the tolerance would be 0.006 inch.

14/11/2008 · Anyone ever see a double positive tolerance? (e.g 1.000 +0.005 +0.008) I've always thought the target value must be between the maximum and minumum value; and was selected by the engineer based on maximizing yield depending on how the part would be made, and on maximizing performance of the final assembly.
