摘要

研究了树脂结合剂金刚石砂轮修整过程中修整力与修整效果的关系

基于修整力的变化表征了砂轮的表面形貌及磨削性能。首先

对碳化硼、碳化硅、白刚玉3种砂轮修整工具进行实验

并采集了修整过程中修整力的变化;然后

利用白光干涉仪观测修整后砂轮的表面形貌;最后

对修整后砂轮进行磨削验证实验

得到不同修整工具修整后砂轮的磨削性能。基于上述实验

分析并验证了修整力的变化与砂轮表面形貌和砂轮磨削性能的关系。结果表明

法向力

能够表征砂轮的磨粒切削刃密度以及磨粒突出高度;修整比率β反映了砂轮的锋锐程度

当β稳定时

砂轮达到充分修整。因此修整力反映了砂轮表面形貌和磨削性能

根据修整力的变化可以把握砂轮的修整进程。

Abstract

The relationship between dressing force and dressing effect in resin bond diamond grinding wheel processing was researched. The topography and the grinding performance of a grinding wheel were characterized by the variation of dressing forces. Firstly

the dressing experiments for resin bond diamond grinding wheel were performed by using boron carbides

silicon carbides and the corundum

and the variation of dressing forces was collected. Then the topography of dressed grinding wheel was observed by a white light interferometer. Finally

the grinding tests were conducted to obtain the grinding performance. On the basis of the experiments above mentioned

the relationship between the variation of dressing forces and the topography of dressed grinding wheel was analyzed and verified. Experimental results show that the normal force

represents the cutting edge density and the protrusion of diamond abrasive

and the dressing ratio β reflects the sharpness of diamond abrasive. In addition

the dressing process is sufficient when β begins to stability. So the dressing forces are related to the topography and the grinding performance of grinding wheels

and the dressing processing is controlled based on the variation of dressing forces.
