Effect of wear behavior of grain cutting edges on chatter vibration in creep feed grinding

Abstract

This paper discusses the effects of the wear behavior of grain cutting edges on the mechanism underlying generation of chatter vibration in creep feed grinding. Grinding wheels were polished using a diamond stick polisher, and an attritious wear flat area was formed on the tip of grain cutting edges. Creep feed grinding experiments were carried out using the polished grinding wheels. After the grinding process, the periodic line and specific peak frequency appeared and the generation of chatter vibration was confirmed. The peak frequency changed in proportion to the workpiece speed. These results revealed the relation between the generation of chatter vibration and the wear behavior of grain cutting.
