Known as the “Doctor of Dimensioning,” Alex Krulikowski is a noted educator, author, consultant, and expert on geometric dimensioning and tolerancing (GD&T). As a design manager with one of the world’s largest manufacturing corporations, he gained more than thirty years of industrial experience putting GD&T to practical use on the shop floor. Alex Krulikowski has a degree in industrial vocational education from Eastern Michigan University and has taught GD&T to tens of thousands through his workshops and seminars, and to countless others through his books, self-study courses, videos, and computer-based training programs. He is a member of the following organizations:

• National and International Committees on Dimensioning and Tolerancing.
• The Society of Manufacturing Engineers.
• The Society of Automotive Engineers.
• The American Society for Quality Control.
• The American Society of Mechanical Engineers.
• The ASME Y14.5 Committee on Dimensioning and Tolerancing
• ASME Y14.41 Committee on Solid Model Tolerancing (past chairman)
• ISO/TC 213-US TAG.

Mr. Krulikowski’s textbook, THE FUNDAMENTALS OF GEOMETRIC DIMENSIONING AND TOLERANCING, has sold over one hundred thousand copies since publication. He has written numerous other books, workbooks, and self-study courses, and his products are used by thousands of colleges and organizations. He has also developed a highly respected computer-based training program, The GD&T Trainer Professional Edition, is being used by corporations to train their employees worldwide.
