Abstract:In order to improve the accuracy of tool monitoring system and the fault-free operation efficiency of CNC machine tool， a design method of tool maintenance system software was proposed to promote the development of unmanned and automatic production in machining process. The system consisted of two parts ： On-line tool wear condition monitoring and tool protection system， which could communicate within the LAN. By modifying the PLC program of the machine tool， the communication between the CNC machine tool and the tool wear condition monitoring system could be realized， which could ensure the real-time transmission of machine tool processing data to the monitoring equipment. And then， the status monitoring function could be completed. The monitoring system was developed with Qt， and the tool maintenance system was developed with Android Studio， and then the system was verified by machining tests. The results showed that the system could timely send a reminder when the tool wear was serious， and tool protection system could also check the latest information of the corresponding monitoring system timely.
