| 摘 要： | 在金属切削过程中,切削区的冷却和切削温度的恒定对于提高切削质量有重要的意义。喷雾冷却是解决切削区冷却的理想方法,为了保证切削温度的恒定设计了一个温度控制系统。以气、液混合喷雾冷却切削的小型二流式喷嘴为控制对象,建立了喷嘴、流量控制阀、执行器以及红外线温度传感器的数学模型,采用比例积分微分控制PID(Proportion Inte-gral Derivative)控制,对冷风和冷却液混合调节切削温度的过程进行了优化仿真。结果表明此控制系统能很好的满足了控制切削温度的要求。

| Abstract: | In the metal cutting,the cutting cooling and the steady temperature are significant for improving the cutting quality.The spray cooling with the mixture of cold wind and cooling liquid through an atomizer is an ideal method.A temperature control device is designed to ensure the stability of the cutting temperature.The mathematic model is established with the atomizer,the flow control value,the actuator and the infrared temperature sensor based on the small dual-fluid atomizer.The traditional PID(Proportion Integral Derivative) algorithm is adopted,and the temperature adjusting of cold wind and cooling liquid is simulated.Results indicate that this device is well satisfied to meet the requirements of controlling the cutting temperature. |
