Uzgodnienie Geometryc Tolerances and Their Importace

Geometric dimensioning and tolerancing (GD Nexmp; amp; T) is a system for definiing and communicating indexering tolerances via a symbolic language on indexering drawings andd computer-generated 3D models that describes a physional object 's nominal geometry ande the permissible odmiana varioon thereof.

Geometric tolerances specify the allowable variation in thee shape, orientation, or location of figures on a dimenred part. Unlike traditional plus- minus tolerancing in theh shape, orientation only controls size, geometric tolerances provide conclussive control over how factores relates te two one another in threeidimensional space.
