  • has conducted GDT training, and consulted on, thousands of product lines (such as satellites, shuttle engines, heart/hip/knee implants, automobiles, motorcycles, armored personnel carriers, submarines, medical devices, computers, a variety of military munitions, pens, computer games, etc.);

  • is an active member of twelve (12) ANSI/ASME/ISO committees, that write the standards for the U.S. and International communities, including Y14 Main Committee Engrg Drawing - Member ; Y14 SC 5 Support - Member; Y14 SC 5.1 Math Def Y14.5 - Member; Y14 SC 43 Funct Gage - Chair; Y14/B89 JWG Spec. for Size & Geometric Toler. - Chair;Y14/SC 45 Support Group - Member; Y14 SC 39 Limits and Fits - Member; Y14 TAG Support - Member; Y14 PT 10.1 Basic Conventions - Member; Y14 PT 10.6 Mech Engrg Doc - Member; Y14 SC 3 Ortho and Pict Views - Member; Y14 SC 36 Surf Symbol - Member.

  • has written 15 books on GD&T, the most current 12 of which are:

1) Geometric Dimensioning and Tolerancing – Applications, Analysis & Measurement [per ASME Y14.5-2009]   Co-published by ASME, this textbook reflects new symbology, rules and basic principle revisions. It shows how to interpret design drawings and CAD representations of product definitions that use the ASME Y14.5-2009 standard. It also explains step-by-step procedures to apply the new Y14.5-2009 practices and allows dimensioning and tolerancing professionals to express their design requirements more clearly.

2) WORKBOOK AND ANSWERBOOK for Geometric Dimensioning and Tolerancing [per ASME Y14.5-2009]  This workbook offers a variety of reinforcement exercises that utilize the concepts discussed in the corresponding text also written by Mr. Meadows (Geometric Dimensioning and Tolerancing – Applications, Analysis & Measurement [per ASME Y14.5-2009]). It covers all facets of geometric dimensioning and tolerancing (basic through advanced applications), tolerance stack-up analysis, statistical tolerancing, measurement, and dimensioning and tolerancing for functional gages and fixtures. This workbook/answerbook also highlights the revised concepts covered in ASME Y14.5-2009.

3) ‘NEW RULES’ in GD&T [per ASME Y14.5-2009]  This 165-page text and workbook/answerbook reflects new symbology, rules and basic principle revisions. This textbook is to showcase only the topics and symbology that have changed from Y14.5-1994 toY14.5-2009

4) Tolerance Stack-Up Analysis This best-selling 325-page combination text-workbook/answerbook of single- and multiple-part assemblies in comprehensive, clear and easy-to-follow.

5) Individual Testing Booklet for Geometric Dimensioning and Tolerancing [per the ASME Y14.5-2009 and 1994 Standards] 

6) ANSWERS to Individual Testing Booklet for Geometric Dimensioning and Tolerancing [per the ASME Y14.5-2009 and 1994 Standards]

7)  Dimensioning and Tolerancing in 2007  The most comprehensive GD&T textbook ever written by a single author has the unprecedented ability to cover almost every facet of tolerancing... all in one book - GD&T and GD&T Advanced Concepts, Tolerance Stack-Up Analysis, Statistical Tolerancing, CMM Measurement, and Functional Gage and Fixture Design - Dimensioning and Tolerancing.

8) Dimensioning and Tolerancing in 2007 Workbook and Answerbook The Geometric Dimensioning and Tolerancing in 2007 Workbook and Answerbook offers a wide variety of practical examples and worksheets that demonstrate the concepts in the corresponding textbook also written by Mr. Meadows (Geometric Dimensioning and Tolerancing in 2007). This workbook/answerbook includes dimensioning and tolerancing applications problems commonly faced by professionals working in design, manufacturing, inspection and gaging disciplines. Geometric Dimensioning and Tolerancing in 2007 Workbook and Answerbook supplies worksheets covering many product types and gives detailed explanations of their answers. It presents the solutions in an easy-to-understand manner. This book also includes a section of word problems that would help prepare anyone interested in taking the ASME Geometric Dimensioning and Tolerancing Professional Certification exam.

It encompasses all aspects of industry and complies with the latest ASME/ANSI/ISO standards. It shows the proper application and interpretation of geometric tolerancing requirements, their analysis and measurement. Included in this Workbook/Answerbook is 1) an Overview of Geometric Dimensioning and Tolerancing, 2) Applications Problems, 3) Word Problems, 4) an Answerbook and 5) a Reference Section with additional illustrations and explanations.

9) Differences and Similarities between ASME and ISO Dimensioning and Tolerancing Standards  This book compares the most important differences and similarities between the ASME Y14.5M-1994 dimensioning and tolerancing standard and ISO standards and technical reports on dimensioning and tolerancing practices.  Unlike other products similar to this on the market, all references in this book from ISO and ASME standards are absolutely up to date as of October 2006.

10) Geometric Dimensioning and Tolerancing This best-selling, 625-page textbook was written to explain the ASME Y14.5M-1994 standard and is already in its 14th printing.  300+ illustrations.  Written in an easy-to-understand format.

11) Geometric Dimensioning and Tolerancing: Workbook and Answerbook  is 340 pages that corresponds chapter by chapter to the above-referenced textbook and the Mr. Meadows' DVD GDT Training Series.

12) Measurement of Geometric Tolerances in Manufacturing is a 455-page, fully illustrated, highly insightful, GD&T measurement and inspection book per ASME Y14.5M-1994.
