Alex Krulikowski

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 30 years of industrial experience putting GD&T to practical use on the shop floor. 

Alex has a degree in industrial vocational education from Eastern Michigan University. He 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. Alex's appeal lies in his encyclopedic knowledge of geometric tolerancing, which he imparts in an accessible, down to earth manner. 

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

Alex frequently speaks at engineering, educational, and designing conferences. His articles appear regularly in trade magazines, including Machine Design, Manufacturing Engineering, Quality Magazine, and OEM Magazine. He also writes the featured article in each issue of ETImail, Effective Training’s quarterly online newsletter. As an expert on the new ASME Y14.41 on tolerancing of solid models, Alex has been quoted in Automotive Excellence and Automotive Industries magazines.

His textbook, The Fundamentals of Geometric Dimensioning and Tolerancing, has sold over 100,000 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. Alex has also developed a highly respected computer-based training program, The GD&T Trainer Professional Edition, which is being used by corporations to train their employees worldwide.

As a consultant, Alex can:

• Provide an expert interpretation of drawings for customers or suppliers 
• Review product drawings for meaningfulness, reasonable tolerances, and critical tolerance stacks
• Evaluate product designs before production release to reduce manufacturing, tooling, and gaging costs through proper specification of part tolerances
• Assist in converting coordinate dimensions into geometric dimensions 
• Review measurement plans 

In 1985, Alex founded Effective Training Inc. The company has become an internationally recognized leader in the field of geometric dimensioning and tolerancing.
