摘　　要：提出了一种新的金刚石砂轮的修整方法,即表面放电辅助修整金属基金刚石砂轮的方法;运用ANSYS有限元分析软件建立了修整过程中金刚石砂轮温度场的仿真模型,并通过VH-800三维数字显微镜观察放电后金刚石砂轮表面的微观形貌来验证仿真结果;在实验研究的基础上,优化了表面放电辅助修整金属基金刚石砂轮的参数设置。A novel truing and dressing method was advanced about diamond grinding wheels, specifically surface discharge assisted truing and dressing of metal bonded diamond grinding wheel. Simulation models of temperature fields were established by finite elements analysis using ANSYS software and observations of surface micro--patterns were made by VH-800 3D digital microscope. Based on the experimental results, parameters for surface discharge assisted truing and dressing of metal bonded diamond grinding wheel are optimized.
