A set of solving scheme of full-closed loop adaptive servocontrol system of CNC machine tool,which could on-line mo-nitor and real-time control,was proposed. The“PC+self-adaption controller”mode was built,through which the accuracy index of the workpiece or factors causing error were on-line detected. The detected signal was fed back to CNC system. Through automatic pro-cessing of CNC system,the cutting parameters were timely adjusted in order that the detected error factors were remained within a rea-sonable limits,so the workpiece accuracy was improved. An open-CNC system based on PC was adopted in order to meet the current development trend of CNC machine tool. All of the scheduled functions were accomplished by software. Furthermore,the degree of automation and the ability of self-adaptive control were greatly improved.
