| 摘 要： | 使用杯形砂轮进行磨削,可以获得较高的加工效率和表面质量.但由于杯形砂轮的平面磨削方式与普通外圆砂轮平面磨削存在差异,故传统的磨削力建模不适合杯形砂轮的平面磨削.为了从本质上解释杯形砂轮磨削力的各种现象,本文对杯形砂轮的磨粒切削过程进行了分析,提出了杯形砂轮有效磨削宽度的概念,分析了杯形砂轮磨削陶瓷涂层时的磨削力,建立了杯形砂轮精密磨削陶瓷涂层磨削力的理论公式.磨削力工艺试验结果验证了理论公式的有效性和正确性.

| Abstract: | High machining precision and machining efficiency can be obtained in grinding WC-Co coating by cup wheel. The conventional model of the grinding force is not suitable for the grinding of the cup wheel due to the difference in grinding style between the cup wheel and the conventional external wheel. So the grit grinding process of the cup wheel is studied, and a new concept of the effective grinding width of the cup wheel is presented. Then the grinding force in grinding WC-Co coating materials by cup wheel is analyzed and a theoretical formula is deduced. Finally, experimental results of the grinding force verify the correctness and the precision of the theoretical formula. |
