Papers by Keyword: Plunge Cylindrical Grinding

Abstract: This paper investigates the temperature field in plunge cylindrical grinding with the aid of the finite element analysis. The analysis included the effect of the variation of the depth of cut and that of the repeated heating and cooling caused by workpiece rotation. It was found that the predictions agree well with the experimentally measured results. The analysis showed that the heating in the consequent rotations further raises the temperature in the workpiece. The reheating in the hardened layer can lead to material’s tempering.

Abstract: Electroplated CBN grinding wheels are not normally trued on a grinding machine and therefore inherently have a degree of run-out. The effect of run-out on workpiece roundness has both been modelled and measured experimentally. As well as affecting roundness, run-out can result in intermittent grinding around the wheel periphery, which can then lead to preferential wear on the most eccentric part of the wheel. This intermittent effect has been investigated by modelling the variation of the normal grinding force around the wheel and by measuring the variation of acoustic emission around the wheel during grinding tests.
