Research On Design And Simulation Of Milling Machining Center Numeralization Prototype

Chinese manufacturing industry faces great opportunity and big challenge, and the machine tool industry is the hard core of the manufacturing industry. Traditional products design and development procedure generally contains sketch design, drawing design, physical prototype manufacture and prototype experiment. This procedure makes long period and costs highly, which can not meet the integrative needs of quality, efficiency and cost. But virtual prototype technology is a kind of completely new one, whose emergence and development brings an innovation to the traditional way of products design. By applying this technology, engineer can make various simulation and analysis on the built virtual digital model of the product, which could help them to find out the potential problems and mistakes of the product in the design period, and then they can amend the mistakes and improve the design sketch quickly. Therefore, applying virtual prototype technology in the process of product design could reduce its dependence on the physical one, which could reduce the development cost, cut the development cycle, improve the design quality and product performance and increase the competition capability of the enterprise.NC machine tool is important and infrastructural equipment enterprise for reconstructing traditional industry and building digital enterprise. As a mechanical and electrical product with complicated structure and high automation, its design has the rigorous requirements on kinematic capability, dynamic capability, mechanical structural capability and machining capability. To assure the design quality of NC machine tool, cut the design period and reduce the design cost effectively, virtual prototype technology should be introduced into the whole design procedure of this product. This paper studied the TH5650 vertical NC boring and milling machine, according to the design requirement, use large-scale three-dimensional software UG to set up the three-dimensional parameter entity's model of the numeric machine tool. Through the graphics interchange format of computer, introduce the geometry models established into ANSYS and UG Motion.With UG Motion on the base of kinematics and dynamics emulation,certificated and analysed the main factor about machine tool creep,and analysed the kinesi stationarity of the TH5650 vertical NC boring and milling machine, then gave some optimization suggestion of the NC milling machine feeding system. On the finite element analysis flatform of ANSYS Workbench, through modal analysis get the natural frequency and the main modal of the machine structure, optimize the structure of machine tool. After completing the simulation analysis, evaluate kinematic & dynamic capability, structure capability and machining capability roundly. It also provided the design with quality assurance and the milling machine improvement with reliable warrant. It not only decreased the design cost greatly, cut the design period enormously when guaranteeing the ultimate quality of the milling machine, but also make the product come into the market as possible as quickly, which brought huge economy benefits to the enterprise.By applying virtual prototype technology, this paper realized the modeling and simulation of the NC milling machine. This method is not only suitable for the design and development of milling machine, but also forthe other machine tool products. And it also can be extended to research, design and develop other mechanical system with complicated structure. So the research method and the consequence in this paper have the significant practical value.
