The course introduces students to GD&T dimensioning, concepts of size control and material tolerances. After defining the terminology used, geometric characteristics and symbols, the course proceeds to demonstrate how the geometric system works and applies to a machined part. Limits of size, MMC, LMC, position verification, product plans and virtual condition, along with the datum reference frame are covered during the course.
