LTU hosting Geometric Dimensioning & Tolerancing (GD&T) workshop

SOUTHFIELD — The Smart Manufacturing and Lean Systems Research Group at Lawrence Technological University will host a Geometric Dimensioning and Tolerancing Workshop on campus Monday, April 16.

The event will run from 7 a.m. to 4 p.m. in Room A200, the Architecture Building auditorium (see www.ltu.edu/map). LTU’s campus is at 21000 W. 10 Mile Road, Southfield. Free parking is available in Lots A or G.

The speaker is John-Paul Belanger, president of Rochester Hills-based Geometric Learning Systems.

Belanger is certified as a senior-level GD&T professional by the American Society of Mechanical Engineers. He has been a full-time GD&T instructor and consultant for 20 years, traveling throughout North America and Europe helping corporate groups implement GD&T properly in design, manufacturing, and inspection activities. He holds a degree in aerospace engineering from the University of Michigan, specializing in aircraft design and safety.

To better define a product, geometric dimensioning and tolerancing (GD&T) is often used as a symbolic way to show tolerances on mechanical drawings. This one-day course covers the GD&T system under ASME Y14.5-2009, including why it reduces costs, how to interpret the symbols, and how to apply these tolerances correctly. Participants will learn the basic definitions and rules, the importance of datums, the meaning of each tolerance, and the impact on manufacturing and gaging. The class is a lecture format, with ample opportunity for questions, and participants are welcome to bring sample prints (with or without GD&T already applied) to discuss with the instructor during breaks or after the class.

After the seminar, attendees will be able to explain the benefits of geometric tolerancing, identify datum features and determine their order of precedence, identify and interpret each of the characteristic symbols, describe the material condition modifers and how “bonus” tolerance occurs, and correctly interpret GD&T feature control frames, and explain the impact on manufacturing and inspection.

This course is ideal for anyone who has a need to apply or interpret geometric tolerances on a product print. Product engineers, manufacturing engineers, CAD designers, quality inspectors, and other engineering and manufacturing personnel will all benefit from becoming fluent in GD&T.

Participants should have knowledge of basic blueprint reading.

The registration fee of $75 includes breakfast and lunch, as well as a spiral binder of course materials. Continuing education and professional development units will be available, and a Certificate of Accomplishment will be provided.
