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.
As a presenter, being professional throughout and being well-prepared is extremely important. It’s a skill that Bob clearly demonstrated throughout his teachings to RB&W members. Bob consistently elaborated on important concepts on GD&T that enhanced the knowledge of all trainees and that’s what RB&W wanted to achieve through taking the course.
