This paper deals with the centerless grinding of complex shaped workpieces which have a through hole or a rectangular groove on the cylindrical surface of them. The shape of roundness of both workpieces centerless ground are analyzed into number of lobes and amplitudes of the lobes. This result showed that the number of lobes and the amplitude of the lobes are determined both by the periodic variations of grinding width on the cylindrical surface of workpiece, and by geometrical work rounding mechanism which is strongly correlated with the center height of a workpiece. And it is also appeared that even number of lobes tends to be formed at the through holed workpiece, and odd number of lobes tends to be formed at the rectangular grooved workpiece. Improving the out-of-roundness is performed by setting the center height lower for the through holed workpiece or setting the center height higher for the rectangular grooved workpiece in centerless grinding.
