Dynamic and Thermal Aspects of Ceramic Processing

Abstract

It is shown that with wheelspeed increasing, grinding forces on ceramics initially drop sharply, pass through a minimum and then slowly rise again. This behavior is explained by a proposed dynamic elastic grinding model. It was possible to obtain information on actual volume of material removal as a function of wheelspeed. Both the depth to which material is removed and width of the groove are substantially larger than geometric considerations would indicate. Both parameters increase significantly with increase in speed. A new piezoelectric dynamometer was designed which enabled study of the impulse of individual cutting events.
