精密陶瓷球体研磨过程中材料去除模型的研究
The study of material removal model in the lapping process of the precision ceramic ball
摘要
Abstract
To understand the material removal mechanism involved in the lapping process of the silicon nitride balls ,a novel model based on three-body abrasion was developed to predict the material remov-al rate (M RR) .According to the theoretic analysis ,simulation and experiments ,it can be seen that the material removal rate of silicon nitride balls during abrasion is connected with not only the process parameters including applied load and velocity ,but also the physical properties and geometry of the ball ,abrasive and tool .It is also found that the nonlinear applied load per ball dependence of M RR is related to the contact area and the indentation of the abrasive ,and it is important to increase the skid-ding of balls for high M RR .关键词
