Even with an understanding of the fundamentals of GD&T, many professionals still lack the confidence to expertly and deliberately apply geometric tolerancing and perform tolerance stack-up analyses to clearly define their product designs. Like with any language, this deeper understanding is built off the fundamentals.
The Advanced course helps students apply GD&T to achieve the mating and functional requirements of their parts. This course reinforces fundamentals and provides applications-based exercises where students apply what they have learned. Applications exercises and calculations are performed individually and in teams. The use of functional dimensioning and tolerancing schemes and its effect on assemblies is emphasized throughout the course. Students will expand their understanding of the implications of their specifications on function, manufacturing, inspection, and quality. Students are introduced to tolerance stack-ups and how variation accumulates through an assembly. Students will gain experience and confidence selecting the product definition strategy for an assembly by working more advanced application examples with their peers under the guidance of an expert in a classroom setting.
Design, manufacturing, and quality engineers and engineering technicians will find this workshop beneficial. Anyone involved with drawing review and anyone looking for a deeper understanding of how to apply geometric tolerancing and perform tolerance analysis will benefit from this course.
At least one Basic GD&T workshop/course is required as a prerequisite. It's essential that individuals understand the underlying principles that the Basic course is focused on teaching. In addition, students should have at least 1 year of on-the-job experience applying GD&T in the development of mechanical specifications.
|About the Workshop Instructor, Charles A. Gillis, P.E.|
Charlie Gillis has over 25 years of machine design experience in industry.
Through his work with Dynamic Design Consulting, LLC, he helps clients with product design, design for assemblability and manufacturability, design documentation, tolerance stack-up analysis, and related capability-building. He has invented and designed mechanical and electro-mechanical devices of great diversity, from high-speed, fully-automated precision mechanisms and manufacturing machinery to kinetic sculptures installed as public art.
He previously served as a mechanical design engineer for The Gillette Company, designing automated machinery for manufacturing blade and razor products. He has designed equipment to manufacture the Mach3, Venus, Sensor3, Fusion, and Embrace product lines.
He has been training practicing engineers in GD&T, Print Reading, and related mechanical design and documentation topics for over 10 years.
In addition to authoring Hammer’s Blueprint Reading Basics (Industrial Press, 2017), he is also a contributing author to Machinery’s Handbook (Industrial Press, 2020), Machine Designers Reference (Industrial Press, 2011) and The Cam Design and Manufacturing Handbook (Industrial Press, 2002).
Charlie earned his Bachelor of Science Degree in Mechanical Engineering from Worcester Polytechnic Institute, and his Master of Science Degree in Mechanical Engineering from Northeastern University. He is a licensed Professional Engineer in the Commonwealth of Massachusetts, and holder of a Geometric Dimensioning and Tolerancing Professional Certificate-Senior Level (GDTP-S) from the American Society of Mechanical Engineering (ASME).
