Relating Tolerances and Kinematic Behavior

Abstract

Designers usually complete the design with nominal dimensions and allocate tolerances only at the drawing stage. This practice can cause the following problems: 1) unnecessarily tight tolerances that require expensive manufacturing processes, 2) parts whose proper functioning is contingent on excessively tight tolerances, and 3) situations where slight wear on a part can seriously modify the behavior of the device. There is a need for computer-based techniques which allow designers to investigate the effect of manufacturing tolerances on the function their design performs. This paper presents a means for capturing the kinematic behavior of a device and relating it to the tolerances on its components. Behavior is represented using a configuration space representation, which we argue will be a useful tool for designers. Keywords: Circuit breakers; Window regulator mechanisms; Computer aided design.
