Dimensioning And Tolerancing Asme Y14.5m-1994 May 2026

The standard organizes geometric controls into several functional categories to manage different aspects of part geometry: Typical Controls Straightness, Flatness, Circularity, Cylindricity

Drawings should define the final part geometry without dictating the specific manufacturing processes (e.g., drilling vs. punching) used to achieve it. Standard Reference Temperature: All dimensions apply at 68∘F68 raised to the composed with power cap F ( 20∘C20 raised to the composed with power cap C ) unless noted otherwise.

Unless otherwise specified, the limits of size of an individual feature of size control both the size and the form (shape) of that feature. Unless otherwise specified, the limits of size of

The standard relies on several fundamental rules that guide how dimensions and tolerances are applied: Unless otherwise specified

Dimensions and tolerances typically apply when the part is in its "free state" and not being forced or bolted down. Key Components of GD&T in Y14.5M-1994
