Oriented Virtual Milling Machine Tool Technology

Manufacturing industry in 21th century requires the enterprises to win market and customers with the fastest time to market , the best quality , the lowest cost , the best service and the cleanest environment . Increasing rivalrousness and responding alterative market rapidly , Virtual Machine Tool is an enabling technology of growing rapidly for reaching this aim , which is used to integrate all kinds of advanced manufacturing models . Numerical control technology (NC) is base on modern machining equipment . Advanced making technic is depended on the development of NC . NC Mill (NCM)is an indispensable means in modern machining . So it is necessary to design a emulational NC software to help us to increase NC program efficiency and quality and to amend the NC environment in the underground of NC Mill , Facing to popular user .On the basis of studying and analyzing abundant references , for improving the machining quality , shortening the machining time , lowering the cost , convenience user , this dissertation proposes the task of "The Research of NCM Virtual Manufacturing Tool (NCM-VMT)" .Firstly this dissertation describes concept, characters and classification of virtual reality and the computer platform, peripheral , application software. Its application to engineering and the key technology is discussed in this part. The method about virtual manufacturing tool is analyzed.Secondly this dissertation discribes how to build the model and environment of VMT . The system builds the three-dimensional mode of milling machine with OpenGL tools in part. The three-dimensional mode is imparted with color, illumination, material and texture. The operation environment of virtual milling machine is realistically built. The operator can operate the virtual milling machine by mouse and keyboard. The monitor is the equipment of output. The operation motion has better interaction and good immersion. This virtual milling machine can be used to train workers simply. It is a basic researching for the application of virtual reality in mechanical engineering. It provides a basement for the further application of virtual reality to engineering.Finally this dissertation discusses how to use VRML to finish file transfer on VMT in Internet and bring forward a way to realization . It supply a base research for the long-distance process .The researches in this dissertation are developed on PC with Visual C++ 6. 0. The VMT system has used developed tools of OpenGL and 3D Max . File transfer rely on Java and VRML .
