The effects of torsional vibration on chatter in grinding

The modelling of chatter in grinding has been the subject of much research. The majority of the theoretical analyses have ignored the effects of torsi onal vibration in both the spindle system and the workpiece drive. A recent paper has indicated that these torsional effects could be significant and a frequency domain analysis has been presented. As the analysis was very co mplex, certain assumptions were made to achieve a linear model. This paper describes a time domain model of chatter in grinding including torsional ef fects, which has the potential to include many non-linear effects that have not been included in any previous analysis.
