The Automatic Programming Software For High-speed Wire Electro-Discharge Machine

A High-speed wire electro-discharge machine (WEDM) is widely produced and used in China, owing to its simple structure, less expensive. Until to now the programs in the WEDM machining are manually created by the operators from their experiences and the drawing data in computers, the automatic programming software with full functions and low cost are urgently needed.In the foundation of massive investigation and basic request of users, this paper using Object-oriented Program (OPP) and the principles and methods in software project has been developed. This software adopting the present most popular Windows operating system underlie platform, has no need to memorize and it enables the obtained menu interactive cartography way to carry on the programming. Its main function is according to the components processing request, completes the two-dimensional graph plan and the processing programming.According to the processing craft condition, the user choice which assigns walks the silk route, the use processing function, after computation processing produces processes the path, the creation of 3B format machining code commonly used in WEDM through post-processing programs, and the transmission of the code to WEDM. The software system also includes process data-base that can help the operator choose machining parameters and standard drawing file interface that can import and export DXF (AutoCAD) files.In the process of program development, with the request precision condition we have used the least arcs to fit the curve, realized curve highly effective programming (processing. We use the establishment curve fitting circular arc mathematical model, it can carry on the optimization to in the curve fitting precision and the fitting quantity.The interface friend, operation simple, functional, easy to use of software system (have been proved by practices.
