Research on the Evaluation of Plane Orientation Error Based on Uncertainty Theory

Abstract:

Based on coordinate measuring machine (CMM) the given part is measured in any orientation, and then the least square evaluation mathematical model of plane orientation tolerance is established. What’s more, the uncertainty evaluation method of orientation error is proposed according to the uncertainty theory of new geometrical product specification (GPS). The face-to-face angularity is taken as the example to present the effectiveness of the proposed uncertainty evaluation method. The result shows that the uncertainty evaluation method not only meets the requirements of new GPS standard, but also ensures the integrity of the flatness inspection results. As a result, the accuracy of the workpiece inspection can be improved.
