[Abstract]:The status data of NC machine tools is the basis of workshop information. With the development of manufacturing automation, the collection, transmission, analysis and application of all kinds of information in production site become more and more important. Most of the domestic CNC systems rely on imports, lack of mature information management system, production information recording difficulties, these problems greatly affect the production efficiency of enterprises. In this paper, the acquisition and transmission of NC machine tool status data is regarded as the object of study on the actual demand of a certain automobile mould company in Tianjin, and a wireless sensing system of machine tool based on ZigBee is proposed. This paper first analyzes the domestic and international research status of data acquisition and wireless communication technology of CNC machine tools, puts forward the problems existing in the data acquisition of CNC machine tools, and expounds the purpose and significance of this research. The structure and main contents of this paper are explained. In this paper, different data acquisition methods are used for different data machine tools, and the overall structure of the system is proposed. The data acquisition method based on macro command and external sensor is applied to complete the software and hardware design of each acquisition module, and the method of data processing and transmission is studied. In the aspect of collecting the spindle temperature, the optimal arrangement of the temperature sensor is put forward, which can meet the need of the collected data to accurately reflect the thermal deformation of the spindle, which provides the condition for reducing the machining error. By means of serial communication technology and macro command acquisition technology, the data collection of spindle speed, machine tool switch machine time, machine tool processing program, part processing start and end time and so on are realized. The wireless sensor network based on ZigBee communication protocol is also tested and studied in this paper. The upper computer management system is designed and the man-machine interaction of the CNC machine tool status information system is realized. The research results show that the wireless sensing system of the machine tool studied in this paper can accurately perceive the running state of several CNC machine tools in real time and accurately, facilitate the information management of the NC workshop, and have good expansibility and certain research value.
