The effect of continuous dressing on the occurrence of chatter in cylindrical grinding

Abstract The technique of dressing a grinding wheel with a diamond roller at the same time as it is grinding, known as continuous dressing, can in certain cases be beneficial in terms of increased stock removal rate. In its application to the cylindrical grinding process, test work has shown that chatter can be a problem. A theoretical analysis has been performed to assess the effects of continuous dressing on stability with particular reference to dresser position, wheel speed and workpiece regeneration. The results show that in many cases the stability limit is reduced by the introduction of continuous dressing, so that due attention must be paid to the machine dynamic stiffness using this process.
