Abstract
Apart from the instability associated with grinding processes, centerless machines tend to chatter more because of the rounding mechanism. A new and general stability chart for the geometrical rounding mechanism is presented, showing that there is no machine setup which can prevent every possible instability related with any number of lobes on the work-piece. However, some stabilising influences exist: among these the effect of machine flexibility has been studied. Finally, new dynamic stability charts are presented showing the effect of the rounding process on the dynamic stability of the system.
