GD&T: The Common Language

Geometric Dimensioning and Tolerancing (GD&T) is a discipline developed to communicate engineering configuration from the designer to the manufacturer through engineering drawings. It is used primarily to alleviate misunderstandings and, thus, provide complete and concise meanings to the production team members.

Seeing the value of GD&T, industry and the Department of Defense adopted American National Standard Institute standard Y14.5 as a national guide ensuring commonality within American industry.

A complete understanding of GD&T is vital for tearing down the walls of misunderstanding.

Knowing The Language Is The Key

The new ASME Y14.5M-1994 standard on dimensioning and tolerancing was released in 1995. The majority of the GD&T symbology has remained unchanged, however there has been some symbol modifications, and a considerable amount of new material added.

When you complete this workshop you will understand the language of GD&T symbology.

We will discuss the changes and the majority of the additional material initiated by the new GD&T standard. The former ANSI Y14.5M-1982 standard will also be covered in detail since most existing drawings were generated to that standard.

Is This Workshop For You?

It is if you need to communicate with engineering drawings.

For those who have no prior knowledge of GD&T, this course will offer material starting at the entry level and progressing to advanced GD&T concepts.

For those with previous GD&T experience, you will receive a valuable update on the latest standard and a thorough review, along with instruction in advanced concepts, which will tie all the GD&T principles together.

Who Should Attend?

• Engineering:

  Design engineers, structural engineers, drafters, drawing checkers.

• Manufacturing:

  Manufacturing engineers, process engineers, planners, machine programmers, tool and gage designers, toolmakers, machinists.

• Quality:

  Quality engineers, CMM programmers, parts inspectors. Others: Managers, project engineers, machined part purchasing, procurement personnel.

What You'll Get Out Of This Workshop

• In this five-day workshop you'll learn how to specify GD&T on design drawings and, thus, convey the right message to engineering, production and inspection personnel.
• You'll learn how to cut manufacturing costs significantly by taking advantage of GD&T concepts that allow maximum production tolerances.
• You'll be exposed to proper inspection techniques for each of the geometric tolerancing controls.
• You'll learn how to design functional gages for part verification.
• You'll learn proper datum specifications to ensure interchangeability of mating parts.
• You'll gain a working knowledge of all elements of ANSI Y14.5M-1982 and the new ASME Y14.5-1994 standard.
• Through actual drawings you'll learn how to avoid common errors encountered with GD&T, both from a drawing and manufacturing standpoint.
• All materials are provided, and you'll receive your own copy of Design Dimensioning and Tolerancing by Bruce A. Wilson, and a binder packed with useful reference materials.

With Our Teaching Techniques You Can Leave This Workshop A Competent GD&T User

In this workshop you will view over 900 overhead transparencies; you'll gain a "hands-on" experience by examining over 130 authentic parts and tools.

To provide feedback on students' progress, quizzes and homework assignments, primarily based on correcting actual drawings, are given each day.

Through the homework and quizzes, you'll find yourself generating design concepts, which properly utilize GD&T principles.

Our Instructor Knows What He's Talking About

MICHAEL SANDFORD began working with GD&T in 1983 as a new employee in the aerospace industry. In his position as a mechanical design engineer, Mr. Sandford has specialized in optic and mechanical packaging. Mr. Sandford has designed machined hardware, castings, tooling and test equipment. He holds several patents in the aerospace industry and has experience in machine shop, assembly and inspection processes. Mr. Sandford has been instrumental in the creation and technical review of design documentation for over 24 years.

Mr. Sandford is a certified ASME Senior Level Geometric Dimensioning and Tolerancing Professional.
