摘　　要：基于磨削热传递模型和磨削去除率模型,提出了一种基于监控功率信号的切入式磨削烧伤仿真预测与控制方法,对砂轮在粗磨、半精磨、精磨、光磨各阶段的磨削功率信号进行监测,再利用计算机对机床数控系统各加工工艺参数进行控制,使砂轮实际磨削功率信号始终低于磨削烧伤最大功率边界的5%~15%,来避免出现工件磨削烧伤现象;同时,用轴承套圈内圆磨削试验验证了该方法的有效性和实用性。According to the model of grinding heat transformation and material removal,a new method for grinding burning simulation prediction and control is proposed based on monitoring power signal.The grinding power signal can be monitored by computer to control the CNC infeed process parameters and the actual grinding power is kept at 5%~15%lower than the maximum power boundary to avoid grinding burn during roughing,semi-finishing,finishing and spark-out stage.And the effectiveness and practicability of this model are proved by the grinding experiment on the inner circle of bear rings.
