Unit Review - Geometric Fundamentals - 1 DVD (58 min) This unit provides a quick review of the geometric tolerancing system. It includes the three steps to establishing datum reference frames, review of the geometric characteristic symbols, the fixed and floating fastener formulas, projected tolerance zone and simple rules of when to use the MMC, RFS and LMC modifiers. Also, discussion selection criteria on the coaxial tolerances, runout, concentricity, profile and position. Information provided in reference to the vector linear, axial and boundary stack formulas.
