Bob Blazewicz Trains and Consults Many Of North America’s Largest Manufacturing Companies

Bob trains using methods that allow your employees to LEARN, UNDERSTAND and RETAIN the GD&T knowledge.

Bob Blazewicz of  2B-Quality was contracted to teach a course on basic Geometric Dimensioning and Tolerancing from the ASME Y14.5-1994 Standard to a group of JLG Engineering Team members. The four day, twenty-four hour course was taught in January 2002 and was well received by our Team members. 
Over the last 6 months Bob Blazewicz was contracted to provide in-house training Geometric Dimensioning and Tolerancing according to ASME Y14.5-1994. Six separate classes have been taught that were attended by over 100 people. Although for years we had been using GD&T, we quickly found that the expertise that Bob brought to the class, gave us an enormous advantage.
We wanted to take this opportunity to thank you for instructing and leading our group through the Geometric Dimensioning & Tolerancing course we completed earlier this month.  It was a pleasure to have you teach the course, and all of our participants learned a great deal about the fundamentals and principles of GD&T.
Bob Blazewicz delivered a four day training class on Geometric Dimensioning and Tolerancing to 12 Behr America Engineering employees in March/April 2003. We were extremely pleased with the quality of his instruction and would recommend his services as a trainer.
First let me say that it was a pleasure having 2B Quality to our campus to provide our first training session on Geometric Dimensioning and Tolerancing. All of the participants found the session to be very informative and “real world” in presentation and discussion.
Bob Blazewicz was in charge of teaching the GD&T course to many of the engineering quality, and production members at RB&W. Through personal experience of going through many training courses, I would say Bob was one who did an excellent job in describing key concepts informatively to ensure all trainees walk away with a clear understanding of GD&T.

Bob Conducts GD&T Training Worldwide

Companies around the world with English-speaking employees are welcome to contact Bob for GD&T training or consulting. He travels worldwide and is happy to visit your country.


What is GD&T?

GD&T (Geometric Dimensioning and Tolerancing) is a three dimensional international engineering language used on mechanical drawings. This language consists mainly of symbols, which are clearly defined in ASME Y14.5M-1994 and Y14.5-2009 put out by the American Society of Mechanical Engineers.

Why do we need GD&T Training?

GD&T will save your company money by providing consistent interpretations, increasing manufacturing tolerances and promoting efficiency and quality throughout the engineering, manufacturing and quality functions.
