[Abstract]:NC-ECCEM technology combines the advantages of CNC technology and electrochemical machining technology, and overcome their shortcomings, the movement of CNC tool cathode in accordance with the instructions, the electrolytic "cutting" way to solve the problem of complex cavity, manufacturing type surface. Through continuous research and development, this technology has gradually improved, and by more and more attention. With the development of computer simulation technology in the field of manufacturing, machining simulation technology is widely used, not only greatly improves the production efficiency, and saves the production cost, and at the same time to promote the development of advanced manufacturing technology. Based on an integral turbine as the research object, two times the development of the use of UG technology, Visual C++6.0 software based on the NC-ECCEM technology and computer simulation integration, to develop a common set of five degrees of freedom control electrolytic machining simulation Really, expand application area of NC-ECCEM technology. Firstly, this paper introduces the structural characteristics of integral impeller and the parametric modeling and 3D modeling of, and introduces its main manufacturing methods, through analyzing and comparing the advantages and disadvantages, laid the theoretical foundation for the selection of NC Electrochemical Machining Technology, and sure the advantage of this technology. Parametric modeling of integral impeller based on NURBS spline tool of UG software, and completes the 3D modeling in UG. Secondly, the paper analyzes the technology of integral impeller NC Electrochemical Machining and the development of the simulation system. The main motion analysis of machining simulation process using UG software UG/Open development tools, according to the design requirements of application menu and user interface. Using Visual C++ software, according to the design of simulation program of integral impeller NC-ECCEM, realize Simulation of material removal, and determine whether there is in the process of collision or interference. Finally, calculation of machining path of integral impeller with the simulation system, machining error analysis and compensation method. The test results and analysis using VERICUT software and NC simulation simulation results were compared, evaluation of the effectiveness of the simulation system the research results show that the precision of integral impeller processing using the simulation system of high accuracy of 0.1mm, leaf, leaf surface quality and good consistency.
