Use of laser triangulation probes in coordinate measuring machines for part tolerance inspection and reverse engineering

摘要

Abstract: riangulation range sensors mounted in coordinate measuring machines are finding increasing use for dimensional measurement applications. These applications include confirming that part dimensions are within tolerances and, in some cases, providing the dimensional database needed to reverse engineer products. This paper summarizes the results of recent studies on the performance characteristics of triangulation probes, describes certain effects which are not commonly understood, and presents concepts for improved designs and data analysis.!12
