Learn how to take the guesswork out of the manufacturing process, to improve quality and avoid costly mistakes.

Course Schedule:
This course runs from 9:30 AM to 1:30 PM and 2:00 PM to 6:00 PM Eastern each day, with breaks throughout.

After taking the introductory GD&T course, students will grasp the fundamentals of GD&T, such as datums, position with Maximum Material Condition (MMC) and Regardless of Feature Size (RFS) modifiers, parallelism, profile etc. However, they may still lack the intimate knowledge of how to apply geometric tolerancing expertly and perform tolerance stacks to define and optimize their product design. 

This Applications and Tolerance Stacks course teaches one how to take GD&T skills to the next level and apply and perform tolerance stacks using a series of case study problems including sheet metal, machinings, plastic parts, castings etc. Being able to identify a tolerance on a part can influence the product’s cost and performance. Learning the skills in this course will help the learner balance functionality with manufacturing capabilities.  

The case studies in this course require students to establish datum reference frames and apply geometric tolerancing based on defined functional requirements. Afterwards, they must perform tolerance stacks to ensure design requirements are met. This process links the concept that the proper selection of the datums, as well as position and profile values on individual parts, have a great effect on the accumulation in the overall assembly. The exercises are interactive and discussed in student groups and as a class to support an engaging class environment.

By participating in this course, you will learn how to successfully:

  • Employ the proper application of geometric tolerancing on parts and assemblies.
  • Perform linear and axial tolerance stacks. 
  • Reallocate tolerances to meet manufacturing capabilities.

Special Requirements
Students should bring calculators to class. Participants may bring drawings to class for discussion.

Who Should Attend?
Engineers, designers and drafters, as well as quality, tooling and manufacturing personnel. As a prerequisite, it is recommended the students attend the Geometric Tolerancing Fundamentals class or have a strong understanding in geometric tolerancing fundamentals.

Patrick J. McCuistion, PhD, GDTPS, was an Associate Professor in the Engineering Technology and Management Department at Ohio University for 25 years. He taught Engineering Graphics, Geometric Dimensioning and Tolerancing, Dimensional Analysis, Quality Management Systems, Microsoft Office Suite, and Technical Writing. Prior to that, he taught three years at Texas A&M University and one year at Pittsburg State University. He worked eight years in various engineering design, drafting, and design and drafting checking positions. He has provided instruction in geometric dimensioning, dimensional analysis, gage and fixture design, and dimensional metrology to industry, military, and educational institutions since 1986. He is certified as an ASME Geometric Dimensioning Tolerancing Professional – Senior grade and as an ADDA Mechanical Drafter.
Dr. McCuistion has authored one book on geometric dimensioning, teaching courses on the following subjects: Drawing Interpretation, Basic Geometric Dimensioning and Advanced Geometric Dimensioning, and authored two, ASME self-study courses covering Drawing Formats, Line Conventions and Lettering, Orthographic and Pictorial Views, Dimensioning and Tolerancing, and Drawing Revisions.
Dr. McCuistion is active in the following ASME/ANSI codes and standards committees: Y14 Main, Y14.2 Line Conventions and Lettering, Y14.3 Orthographic and Pictorial Views, Y14.5 Dimensioning and Tolerancing, Y14.5.1 Mathematical Definition of Dimensioning and Tolerancing Principles, Y14.5.2 Certification of Geometric Dimensioning and Tolerancing Professionals, Y14.8 Castings, Forgings, and Molded Parts, Y14.35 Revision of Engineering Drawings and Associated Documents, Y14.36 Surface Texture Symbols, Y14.43 Dimensioning and Tolerancing Principles for Gages and Fixtures, Y14.45 Measurement Data Reporting, and Y14/B89 Joint Advisory Committee (JAC1) on the Specification of Notation to Support Requirements for Size and Geometric Tolerances.
As Chair of the national SkillsUSA Technical Drafting competition, Dr. McCuistion creates the yearly design and drafting problem with solutions and a written test and coordinates all competition details.  The problem to be solved includes drawing and assembling 3D computer models of a product and creating dimensioned 2D views of those models based on national drawing standards.
