MECH-226 - METROLOGY AND GEOMETRICS  3 credits
This course introduces the student to three key concepts within the quality function: the metrology system, measuring and gauging, and geometric dimensioning and tolerancing (GD&T). Topics to be discussed include managing the metrology system, calibration procedures and standards, types of measuring equipment, instrument classification, analysis and presentation of measurement data, and measuring and gauging geometric tolerances. Emphasis is placed on GD&T theory and discussions, based on ANSI Y14.5M-1994, including measurement of flatness, straightness, roundness, cylindricity, parallelism, perpendicularity, concentricity, position, and runout. Lab exercises demonstrate key principles discussed in lecture.
