Fundamentals of GD&T Class – 3 Days

November 16th – 18th, 2020

Prerequisites: Blueprint Reading Skills (recommended)
Text: GEOTOL Pro Fundamentals Workbook 2009
Instructor: Jacek Macias
Location: 302 E. Main St., East Dundee, IL 60118

Our GD&T training class is a basic, practical, & straightforward approach to geometric tolerancing and conforms to the Standard ASME Y14.5M-2009. In this program, we focus on the “what, when, why, and how” of GD&T.  The main objective is to bring all participants to a common, basic, and operational level of understanding. This basic GD&T class will benefit employees in many different roles in manufacturing including inventors, designers, engineers, quality inspectors , machinists, cnc operators, and many more!

Participants will leave the course with a comprehensive understanding of basic GD&T principles and their applications, and will also know how to interpret GD&T on engineering drawings. Attendants should have a basic knowledge of how to read blueprints and engineering drawings prior to taking this course.

  • The expert-led training reviews the history of GD&T and will provide an in-depth study of geometric characteristics and tolerance zones, in an easy-to-understand format.
  • The class is lecture-based, but also provides time for classroom discussions. We encourage students to bring their own drawings to share their struggles and to learn from others. (with permission from your company, of course!)
  • Each participant will also leave with a GD&T Pocket Guide which serves as an excellent resource post-training — A small, quick reference when you’re looking for help on the job!

Advanced GD&T Class – 2 Days

November 19th – 20th, 2020

Prerequisites: Blueprint Reading Skills, Basic fundamental knowledge of GD&T (recommended)
Text: GEOTOL Pro Fundamentals Workbook 2009
Instructor: Jacek Macias
Location: 302 E. Main St., East Dundee, IL 60118

This course is intended for experienced users of concepts of ASME-Y14.5-2009 standard. Designed to cover the more advanced applications of geometric dimensioning and tolerancing, participants will leave the course with an understanding of how to apply the principals as well as a deeper understanding of GD&T benefits.

Improve efficiency through appreciation of the concept of inspection-oriented tolerancing, testable datums, and a true cost of undue constrains placed on the geometric aspects of design. Reduce time wasted by designers , manufacturers, and inspectors by increasing their awareness of downfalls of using incomplete drawings or drawings with incorrectly applied GD&T. This advanced course is aimed to provide a solid understanding of datum selection, tolerances zones and application of advanced geometric tolerancing theory. Students will be effectively trained on how GD&T controls the functions of complex designs and it’s ability to communicate geometric tolerances appropriately on their own prints.  

  • Datum Reference Frames – Datum selection and what it means for manufacturing and inspection
  • The applications of position tolerance are explained in detail including fixed and floating fastener formulas.
  • Composite and Multiple Single Segment Profile Tolerancing
