Sampling Techniques for Coordinate Measuring Machines

点击翻译按钮获取中文摘要

This research project will systematically examine the interaction between the various procedures involved in measurement of mechanical parts using coordinate measuring machines (CMMs). The areas of special study include the systematic, random and stochastic errors in coordinate measuring, the sampling methodologies appropriate to different part geometries, and the algorithms used to analyze the coordinate data to produce mathematical descriptions of geometric entities. The interaction of these three factors in determining conformance to design intent (tolerancing systems) will be addressed.
