摘　　要：对组合机床在孔的复合加工过程进行了研究,在分析了切削速度对孔的加工精度的影响,设计了一种模糊PID调速控制方法来解决钻铰组合机床只有一种切削速度的问题。建立了钻铰组合机床的数学模型,结合系统传递函数在Simulink环境下进行了控制仿真。结果表明:与传统PID控制相比,模糊PID控制器拥有更好的动静态性能,能够适应组合机床加工时的调速需求。Do research on composite process of the combination of machine tools in the hole, analyze the effect of cutting speed on machining accuracy of the hole. In order to solve the problem that traditional drilling and reaming combination machine tool has only one cutting speed, design a fuzzy-PID speed con- troller. Build the mathematic model of combination machine tool. Have simulation combine with system transfer function in Simulink environment. The results of simulation show that comparing with traditional PID controller; fuzzy PID control has a better dynamic and static performance. It can match up with the requirement of speed control while the combination machine tool in operation.
