New Multimedia Geometrical Tolerancing Course

Abstract The new application Geometrical Tolerancing developed for usage during lectures at technical universities as well as for the enhancement of vocational trainings for design, manufacturing and metrology engineers working in industry is presented. The application capabilities are shown and discussed on base of the selected screen shoots. The suggestive 3-D animations and multicolour drawings with intuitive user interface are employed to effectively familiarize the application user with definitions of form, orientation, location and run out tolerances. The tolerance zones for toleranced integral or derived features are clearly visualized and then shrunk to show particular deviations. The role of the datums and datum systems for establishing involved tolerance zones is explained in details. The restrictions for the part geometry imposed by specified maximum material requirement or least material requirement that combine requirements for size of the features of size and the geometrical tolerance to one aggregated functional requirement are shown. The concepts of the geometrical deviations evaluation by coordinate measuring techniques or workpiece verification by hard gauges are demonstrated for the selected tolerances with case studies.
