Abstract

Abstract

It will be able to get a better surface quality in the precision honing of the engine cylinder liner with thetechnology of power ultrasonic machining. The grinding force is related to the ultrasonic vibration, which affects thematerial removal, grinding heat and the surface quality. Based on the material removal mechanism of ultrasonichoning and the grain distribution on the surface of oilstone, the ultrasonic honing force model was established, whichincluded material chip deformation and friction situation between grain and workpiece. With the simulation resultsobtained by using the established force model it can be found that the grinding force is affected by the processingparameters and the physical change of materials; the ultrasonic honing force is decreased by more than 50%compared with the traditional honing under the same processing condition, and the ratio of normal force to tangentialforce is also increased; the average dynamic friction coefficient decreases under ultrasonic vibration, leading to thereducing of average tangential force; the honing depth is more significant to affect the honing force than the spindlespeed, and the honing force begin to decrease gradually when the spindle speed is higher than 620 r/min.
