【Abstract】 Aimming at solving the problems in domestic Wire-EDM’s existing situation , the thesis puts forword an approach of the machining system of Wire-EDM DNC ,on base of the technology of computer network,database,DNC,NC and compter communications at present. The thesis introduces the framework , function module of the machining system of Wire-EDM DNC and analyse the key technique & principle in developing the system. The system has been verified to be a good method of improving automation in WEDM in pratice. Presently. The whole thesis as follows:In chapter 1, the principle and application area of WEDM is introduced and the problems in exitsing situation are described. Based the research in exiting situation,the importance of implementing the machining system of Wire-EDM DNC.In chapter 2, the famework , characteristic and function of the machining system of Wire-EDM DNC is introduced and some key technology in realizing the system is also described.In chapter 3, some key technique used in realizing the module of wire automation programming system is discussed. The method of building machining path automaticly, disposing of track , displaying the cutting track of NC code and capturing vectograph from digital image is also researched in detail.In chapter 4, the key technique using in developing communication module is discussed. Then an approach of hetero-structure WEDM NC system communication and multiple serial port communication is put forward.In chapter 5, the makeup and function of the system software is designed firstly. Then the process of developing automatic programming system of WEDM is presented .The system is developed using the tool of VC++ and Object ARX in the platform of AutoCAD.Last,some arithmetic discussed in the above paragraphs is realized.In chapter 6, the machining system of WEDM DNC discussed above paragraphs is put in practice as the platform of 2D innovative design in WEDM of Zhejiang University. It has been verified that the system is a good method of farthest using machinine tools and improve the produce efficiency distinctly.In chapter 7, the work of the dissertation is summarized and the further research work is prospected.更多还原
