Unformatted text preview: mptions about the fundamental form of the underlying probability density function of errors are required. Examples are presented to both illustrate the proposed methodology and validate its performance. The use of this method reduces inspection cost as well as the cost of rejecting good parts or accepting bad parts. Keywords: Tolerances, Minimum Deviation Zone, Inspection, Adaptive Sampling. 1. INTRODUCTION Effective evaluation of geometric deviations of fabricated sculptured surfaces for the purpose of determining compliance with specified form tolerances is an important metrology and inspection task. It requires the acquisition of numerous measured data points and an extensive computation of surface geometry errors to accurately characterize the inspected part geometry. Numerous research projects in the area of tolerance evaluation based on discrete measured points were undertaken. However, there is still a need for robust methods to accurately evaluate complex sculptured surfaces. Surface inspection is traditionally accompli...
