Geometric Dimensioning and Tolerancing (GD&T) Training in accordance with ASME Y14.5M-1994 and Y14.5-2009 Standards

2-B Quality provides training courses in the fundamentals and advanced concepts of geometric dimensioning and tolerancing (gd&t) in accordance with ASME Y14.5M-1994 and Y14.5-2009 standards. Training is conducted at customer's facilities or at the office of 2-B Quality located in Kitchener, Ontario, Canada.

What is Geometric Dimensioning and Tolerancing? GD&T is a three dimensional international engineering language used on mechanical drawings. This language consists mainly of symbols which are clearly defined in ASME Y14.5M-1994 and Y14.5-2009 put out by the American Society of Mechanical Engineers. This is the drawing standard used in North America and recognized throughout the world. It replaces the earlier ANSI Y14.5M-1982 standard and has been expanded to be almost identical to its ISO counterpart. The standards are complete in identifying ways of using the various geometric symbols and other methods to clearly show the designer's intent.

Why do we need Geometric Dimensioning and Tolerancing (GD&T)?

Proper use of geometric dimensioning and tolerancing guarantees the form, fit and function that engineering intended without assumptions in the shop or elaborate notes that everyone interprets differently. GD&T will save your company money by providing consistent interpretations, increasing manufacturing tolerances and promoting efficiency and quality throughout the engineering, manufacturing and quality functions.

Our experience has revealed, that many designers, shop and quality control personnel, although working with GD&T over several years, do not fully understand the requirements and/or do not utilize all the benefits of GD&T.
