Research Abstract

Micro form on the surface of machine parts which have geometrically curved surfaces influences the function and quality of the mechanical devices. Therefore the quality of those parts is inspected using the curve measuring machine. However, the accuracy of the gauge used for evaluation and calibration of curve measuring machines is not high and thus it is difficult to warrant the high accuracy of those measuring machines. In order to solve this problem, the evaluation/calibration method using the gauge for curve measurement which is composed of plane and cylinder is developed. The proposed method is theoretically analyzed. Experiment is carried out and the effectiveness of the method is confirmed.
