円筒形状の離散測定におけるサンプリング間階

抄録

Sampling interval in a measurement of cylindrical form by means of the discrete data is studied in this research from the viewpoints of form error, wave length to be analysed and measuring accuracy. Namely, circumferential and axial sampling intervals of the cylinder surface are proposed from the analysis of auto-correlation function with considering the ratio of the difference between the original profile and the linear-interpolated profile of neighboring discrete data to the magnitude of the original form errors as a criterion.
