摘　　要：本次数控改造是在原有三轴联动数控机床基础上,增设第四轴控制,即数控回转工作台,形成四轴联动较高端数控机床。进行数控系统整体方案设计,确定主要技术方向;进行伺服系统分析,确定硬件选型及主要参数;对PMC进行解析,明确程序、地址、输出模块配置。把数控回转工作台的运动和原有的三轴联动控制结合起来,形成四轴联动数控机床控制。利用PMC的诊断功能,查找及解决设计过程中的问题。硬件连接好数控回转工作台后,正确选择伺服放大器和伺服电机等,修整PMC的控制系统的输入输出信号、梯形图,I/O地址、脉冲模块,调整PMC参数、诊断、速度,达到四轴联动电气控制的设计要求。This NC transformation is to add the fourth axis control,namely CNC rotary table,on the basis of the original three-axis linkage CNC machine tool,to form a high-end four axis linkage CNC machine tool.Design the overall scheme of the CNC system and determine the main technical direction;Analyze the servo system,determine the hardware selection and main parameters;Parse PMC and specify program,address and output module configuration.The motion of the NC rotary table is combined with the original three-axis linkage control to form a four-axis linkage NC machine tool control.Use PMC diagnostic function to find and solve problems in the design process.After the hardware is connected to the CNC rotary table,correctly select the servo amplifier and servo motor,trim the input/output signal,ladder diagram,I/O address,pulse module of the PMC control system,and adjust the PMC parameters,diagnosis,and speed to meet the design requirements of the four axis linkage electrical control.
