A case study of multi measurement strategy on 3D measurement

Abstract

Making sure of relationship between probing points and uncertainty, multi measurement strategies are used. It is one of the techniques for evaluation of the uncertainty of measurement. Workpiece having bad form error, say 40μm, is measured. On circle measurements, probing points are varied from 5 to 12. Error from strategy varies from 8 to1μm. This variation of error derived from the number of probing point is compared to the simulation, and they come to an agreement
