| 摘 要： | 基于冲量理论和振动加工理论,采用叠加原理建立了工件横向施振超声振动磨削力数学模型。从理论上解释了工件横向施振超声振动磨削力低于普通磨削力的原因,并进行了超声振动与普通磨削力对比试验研究。结果表明:超声振动磨削力比普通磨削力减小20%~30%,磨削力的大小随工作台进给速度的提高而减少,磨削深度的增加而增大,当达到某一临界切深时,磨削力急剧下降。磨削力可做为评价陶瓷材料脆延转变的一个重要参数。

| Abstract: | Based on impulse theories and vibration cutting theories,the mathemetical model of work ultrasonic vibration grinding(WUVG) forces was established.The reason why WUVG forces are lower than conventional grinding forces is presented.The characteristics of the grinding force in ultrasonic vibration grinding in comparison with those in conventional grinding(CG) were studied.The results indicate that the grinding force in WUVG is about 20% to 30% less than that in CG.The increase of worktablevelocity leads to the decrease of the grinding force and thegrinding force increases with the increase of the grinding depth.The grinding depth decreases sharply at a critical depth.The grinding force is a significant parameter for evaluating ceramicmaterial transformation. |
