The measuring accuracy of the multistep methodin the error separation technique – C. Linxiang et al.

Abstract

The multistep error separation technique is a high precision measuring technique. It is widely used to measure the radial, axial and composite errors of rotating pick-up roundness measuring instruments, turntable roundness measuring instruments or precision axis systems. The author deals with the problems of measuring accuracy of the multistep method and the determination of the required number of sampling points. Theoretical analysis and experimental verification are presented.
