Solid Models, Virtual Inspection and the Position Tolerance E. R. Evans, Jr. School of Engineering Engineering Technology Penn State Erie, The Behrend College, Station Road, Erie, PA 16563 ABSTRA CT - In industrial p ractice, p osition is the holes are within the p rescribed p osition tolerance. This most widely used geometric tolerancing characteristic. activity reinf orces the concep ts discussed in class and A thorough understanding of the concep ts associated introduces students to the virtual version of some of the with p osition tolerancing is, theref ore, an essential skill insp ection methods used in industry. that graduating engineering and engineering technology students should p ossess. In the Mechanical I. Introduction Engineering Technology p rogram at Penn State Erie, Position tolerance is the geometric tolerance The Behrend College, geometric dimensioning and characteristics most commonly used in industry. When tolerancing (GD T) skills are introduced to students calculated and applied properly on a drawing, mating during an advanced solid modeling course. Position parts manufactured according to the drawing tolerance is discussed in class p roviding a basic specifications will always assemble properly. In order to understanding of the geometric control, the use of be able to quickly contribute to design efforts on the datums and the concep t of app lying the maximum j ob, engineering and engineering technology students material condition modif ier to the tolerance value.
