Research On The Simulation System Of High Speed WEDM

After lots of investigation of the internal and external methods on modeling of wire EDM process, the dissertation presents an attempt at modeling the process through different ways on different high speed WEDM machining, a predictive system software is developed. Machining effectiveness prediction and parameters optimization is considered in this software. Moreover it can be used on different wire EDM machine tools through models training module. It is verified that accurate results has been provided through Artificial Neural Networks on different high speed WEDM machines. This method can be used to guide the proceeding of production. In this paper, some research and achievement are made.1. through the comparison between high speed WEDM and low speed WEDM, problems and the trend of development of high speed WEDM is brought forward. Then the modeling methods on modeling of EDM domestically and abroad is given. The idea of establish a simulation system to predict technological performance and optimize machining parameters is given.2. a simulation system of Fast-cutting Wire Electrical Discharge Marching (WEDM) process will be put forward, analyzed it's feasibility in the abstract, and discussed it's framework and realization project. Pointing out that the key problem is to build a accurate and effective model of WEDM.3. for the DK7725e which has no complete database, based on the understanding of WEDM's technics rules, comparing some kinds of experimental design method, and a central composite rotatable experimental design method will be used to get some test data of DK7725e.4. for the DK7725e which has no complete database, based on test data nonlinear regression model and RBF Neural Networks model are brought out. Verification experiments have been carried out to check the validity of the developed models.5. the makeup and function of the process simulation system software is introduced firstly, then the particular design of the master module, database module, models training module and simulating module is discussed.At last, the work of the dissertation is summarized and the further research work is looked ahead.
