Why GD&T?

(Based on ASME Y14.5M-1994)


To allow Participants to master techniques of GD&T in the ASME standard to;

integrate smoothly into engineering design applications and modern inspection systems at work.

Provide Participants with Fundamental concepts of GD&T to express, understand and interpret drawing requirements using GD&T to ANSI / ASME Y14.5M Standards.

In-depth knowledge of GD&T application allows optimum form, fit & function between the various complex pieces of parts assembly.

Starting with basic principles in coordinate dimensioning & tolerancing and progressing on these principles to understand & apply GD&T requirements to ad concepts to real work applications.

Application & Advantages of GD&T

The Definitions


Fundamental Rules. -application examples on sizes and dimensions. Dimensioning and tolerancing philosophy.

There are some Fundamental Rules that need to be applied.These can be found on the GD&T Rule Based System.

ASME StandardsASME Y14.5 – Dimensioning and TolerancingASME Y14.5M-1994 Dimensioning and TolerancingASME Y14.5.1M-1994 Mathematical Definition of Dimensioning and Tolerancing Principles

Many multi-national corporations use ASME Y14.5 (ASME Y14.5M-1994 or ASME Y14.5-2009) as their GD&T standard worldwide for all of their international operations.

The ASME Y14.5 standard is considered the authoritative guideline for the design language of GD&T.

ASME Y14.5-2009 is a replacement of ASME Y14.5M-1994.

ISO 1101:2004 Geometrical Tolerancing.

Standards for GD & T. – ASME, - ISO, - Din The International Organization for Standardization (ISO) also has a version of GD&T, which they call ISO 1101 Geometrical Dimensioning and Tolerancing (GD&T).

At present the ISO standards do not recognize the interpretation of concentricity and symmetry as defined in the ASME Y14.5M 1994 standard.

The concentricity and symmetry characteristics in ISO have the same interpretations as the position characteristic in the ASME Y14.5M 1994 standard.
