Development Of Automatic Material Cutting System And Milling Machine System Based On PC's Management And CNC's Control

Automatic CNC system based on HUST's control is one set of three-axis linkage mechatronic platform designed completely by our lab team independently. Mechanical technology, electrical control technology and PC management technology have been used in this platform system. This platform has highly practical value and system integration. On the base of this platform, we can make practical machine tool. In these years, high-precision numerical control machine tool market has been occupied almost by foreign companies, and with the development of our country economic , the need of the high-precision numerical control machine tool will be more and more increasing . So it is very necessary to make this platform be the practical product.High-precision numerical control milling machine is an important focus in the machining industry. To make clients satisfied, roughcasts must be processed to be as clean as a whistle. In addition ,The board material is one kind of important architectural and ornamental material that are used widely in many fields such as building construction, furniture manufacture. Board cutting is one of the important working procedures in the board machining process. At present, compared with the same type of foreign products, home-made numerical control equipments still have disparities in location precision, cutting speed, running dependability and so on. So, domestic factories generally use imported numerical control equipments. During these years , with the development of information technology represented by computer technology, Computer Integrated Manufacturing (CIM) has been applied to manufacturing industry gradually. Production mode of the enterprise is changing from single automation of producing process to integrated automation of all the process including product design, product manufacturing, quality assurance and so on. Referring to some advanced technology of foreign countries and following the basic idea of CIM, analyzing how to develop a complete Numerical Control Milling Machine system based on PC management and CNC control, and making the Board Cutting system based on the platform system which has been succeeded already are the two main objects of the dissertation.After briefly introducing the development of numerical control technique and the conception of CIM, the dissertation analyzes the functions of the hardware configuration of the platform including Mechanical design , electrical control design and PC management design etc. Then some main parts of the Numerical Control Milling Cutter software development such as extraction of drawing information ,the communication between super-computer and sub-computer are expatiated on. To the sub-computer module, the dissertation mainly presents design of building the track of the cutter center automatically according to the parameters.In addition, the rest of this dissertation mainly discuss the new ways, which are used in Board Cutting system, including how to build the minimum encircling rectangle of the random drawing automatically and two-dimension cutting stock algorithm etc.At last, Some proposal of improving system is brought forward at the end of the dissertation. The Numerical Control Milling machine system has been used to work in the factory. Until now ,no problem has been found , The system works well.
