GD&T Fundamentals
GD&T Fundamentals
Who should attend:All those who use GD&T to design, produce and inspect parts: mechanical engineers, designers, managers, production planners, inspectors, machinists, supplier quality personnel, etc.
The Need:A concurrent engineering team equipped with the proper tools has the ability to shorten time to market, reduce engineering changes and create a robust quality design. Design decisions should be optimized for quality cost and delivery at the sketch phase when an engineering change costs a few cents rather than hundreds or thousands of dollars months later. The drawing is the common thread of the concurrent engineering team.
This is the first in a series of seminars that presents understandable user friendly tools that may be used by your entire team to get it right the first time. By using these methods, design decisions are based on fact rather than emotion and past practices.
Course description: (3 days)You'll discover the major pitfalls of traditional coordinate tolerancing - and how they may be overcome by using Geometric Tolerancing. Then, starting with your basic blueprint knowledge, you'll learn the symbols, terminology and rules of Geometric Tolerancing as prescribed in the current standard (ASME Y14.5M-1994). The GD&T Hierarchy will be presented to explain the relationship between tolerances and how to most economically apply the concepts.Introduction
