Abstract


High speed wire cutting machine, which is an original electric machining facility created in China, is widely produced and used in China owing to its low price, simple structure and effective technology. With the widely applied of high speed wire cutting machine in the aspects of mold manufacturing, mold cutting, difficult-to-machining materials and machining of complex-profile products with high precision, the requirement of the automation degree of high speed wire cutting machine is higher and higher, and the automatic programming software of high speed wire cutting machine is playing a more and more important role. However, the automatic programming software made in china has defects of tech hysteresis and inconvenience, and import automatic programming software has poor universality and is hard to use. This limits severely the production efficiency of cutting machine. Therefore, it has important practical significance to.research suitable for china’s automatic programming system of high speed wire cutting machineThis article designs and develops an automatic programming system of high speed wire cutting machine on the basis of discussion of research status on high speed wire cutting technology and the automatic programming system of the existing high speed wire cutting machine. This paper mainly covers the following research work: The design of the graphic drawing module has been completed.It can achieved basic graphics, graphic edit and file management. By analyse on the construction of DXF file and the meaning of group code and group value, the system gets information successfully and redraws automatically. The system achieves transfering of any atically two-dimensional graphics to the automatic programming system on AutoCAD 2007 .The system can export DXF files of the graphic information which is drawn in the graphic drawing module. By sequence of the graphic information, the system can generate the ordered list with the user specified processing order. The system comprehensive studys all sorts of connections of the two adjacent entities and gives the users the choice of two way corner of the transition. By processing wire electrode offset and corner transition, the system achieves a smooth transition of wire accurately. By research 3B codes and G codes, the system realizes in the two NC code . At last, by studying the simulation algorithm based on the interpolating technology, the system achieves graphics simulation of the processing track.With Windows XP as the operating system, Visual C + +6.0 as a programming tool, programming of graphical interaction, The system interfaces friendly and operates easily, shortens programming time and improves the accuracy of the programming.
