Research Of Simulation System Of NC Milling For Virtual Manufacturing

With the popularization of numerical control technology, gradually simulation and optimization of nc machining technology gets more and more widely, how to improve the efficiency of the nc processing machinery industry has become one of the important research topic. Using a virtual simulation system of physical simulation, and the cutting process can be related to the change of physical factors will be mapped into the virtual manufacturing system, the actual process analysis and prediction of cutting parameter before the change and interference factors in the process, reveals the essence of machining process. So, if the actual cutting through computer simulation and can estimate product function, performance and manufacturability aspects of possible problems in actual processing, can obtain the optimum before the machining parameters, avoid the traditional processing parameters according to the manual or experience the conservative, greatly improving people choose the forecast, give full play to the level of potential, to improve the machine parts processing efficiency has important significance.Based on the collection and read a lot of relevant material, on the basis of the choice Unigraphics NX) (UG platform development technology, using quadratieally of virtual nc milling of simulation system is studied by using VISUAL c + +, after the study of the system can be used to build simple parameterized simulation platform entity model and virtual machining process can be executed in machining simulation, on the basis of milling machining parameters in certain conditions, practical calculation planning process of the most suitable for cutting dosages, to calculate the cutting parameters for processing after the combination of every one knife including modifications, realizes the step of physical simulation of geometry and combined with MATLAB, the graphic display function optimization cutting parameters that before. Examples of the system test, primarily validated the effectiveness of the algorithm and the research methods and the correctness.
