Abstract

This paper deals with the restraint of a jumping motion of a workpiece in the heavy-duty centerless grinding of a multi-diameter shaft. The figure accuracy, such a roundness or straightness, of the multi-diameter shaft tends to be worse than that of the uniform diameter shaft in centerless grinding.

It was determined both analytically and experimentally that the deterioration of the accuracy was caused by the jumping motion of the workpiece, when it was affected by an upward frictional force from the regulating wheel.

The analysis also specifies a stable grinding condition and makes it possible to improve the accuracy in heavy-duty centerless grinding for multi-diameter shafts.

    A total of nineteen papers have been published and one keynote paper was presented by Rowe et al. [117]. Seven papers are related to the improvement of roundness including the rounding mechanism and regenerative chatter vibration [16,21,61,74,94,147,148], seven examine high efficiency grinding including workpiece support stability [11,56,59,114,118,125,141], and five are on optimization and simulation [45,46,58,83,132]. Fig. 1 shows the evolutions of roundness and throughfeed rate of parts ground by centerless grinding in comparison with the change in the average fuel economy of passenger cars since the birth of centerless grinding.

    However he did not take into account the negative effect of large grinding force ratios in spinning phenomena (Fig. 2). In this paper the same approach as in previous works in the literature [6–8] has been used to solve the generalized rotational stability problem. Next, a work rotational motion and stability analysis tool has been developed.
