摘　　要：为了探究超薄金刚石砂轮磨削硬脆材料的过程,用扫描电镜观察磨粒在微观层次下砂轮表面的分布情况.通过ABAQUS二次开发,采用圆外切线法建立不同形状的磨粒,根据粒度、内圆半径等参数生成磨粒有序位置的三维砂轮表面;在ABAQUS中采用部分砂轮对氧化铝陶瓷进行磨削仿真,输出磨削力.使用DS610划片机对氧化铝陶瓷进行磨削实验,验证了三维模型的准确性.In order to investigate the process of grinding hard and brittle materials with ultra-thin diamond wheel,the distribution of abrasive particles on the surface of the wheel was observed by scanning electron microscopy(SEM).Through the secondary development of ABAQUS,the outer tangent method of the circle was used to establish the abrasive particles of different shapes,and the three-dimensional grinding wheel surface with the orderly position of the abrasive particles was generated according to the parameters such as particle size and inner circle radius.In ABAQUS,some grinding wheels were used to simulate the grinding of alumina ceramics,and the grinding force was output.The accuracy of the 3D model was verified by the grinding experiments of alumina ceramics with DS610 scribing machine.
