摘要
分析了新研制出的高速高性能研磨机的运动原理,为了确定研磨盘磨损形态,建立了研磨盘磨损仿真模型,该模型通过求出研磨盘子圆环区域覆盖面积分布,预测了研磨盘径向不同区间的磨损情况。仿真表明,切削速度提高,研磨盘磨损减小;切削速度一定时,研磨盘靠近内外径区域磨损明显大于中径区域,且研磨盘径向方向的磨损基本对称。将研磨盘磨损仿真模型应用到其它研磨机的结构设计之中,可保证研磨盘的平面度,减少生产加工时的修盘次数,降低加工成本。
For prediction purpose at grinding wheel wear, the grinding disc wear simulation model is necessary. The kinematic theory of high-speed and high-performance grinding machine is analyzed, based on the analysis to es- tablish grinding disc wear simulation model, it will be possible to calculate the grinding wheel wear. The simulation shows that cutting speed leads to reduce grinding disc wear and the maximum wear at the inner and outer range of the grinding disc. The simulation model allows the calculation of the distribution of the grinding wheel wear for the first time and wear optimized process strategies and requirement-oriented tools can be developed.
