APM 201 - GD & T and Precision Fits

Credits 5
Students will study the theory and application of the use of standard tolerances and GD&T concentrating on geometric dimensioning and its relation to engineering drawings. They will understand the feature control frame and center on basic dimension, form (straightness, flatness, cylindricity, circularity), profile of a line and surface, orientation (angularity, perpendicularity, parallelism), location (position, concentricity, symmetry), and total runout. The student will appraise the Maximum Material Condition, Least Material Condition and Regardless of Feature Size. Calculation of true position, bonus tolerance, datums and datum targets, fixed fastener and floating fastener formulas will be examined. Students will learn Rules #1 - #2.
