Programming And Post Processing Techniques Of Periscope Side Cover Terrace Die Based On UG

Numeral Control technology, shorter form NC technology,is the important foundation and key technique of the mechanical machining modernization and' military industry development. NC machining can greatly improve the productivity, stability and processing quality, shorten the processing cycle, improve production flexibility, carry out the automatic manufacture of all kinds of complicated and exact parts, achieve the CAD management in factories and workshops, reduce the number of equipment in plants, save labor of manpower, improve working condition,accelerate the developing and updating speed of the products,and enhance the ability of the corporations to adapt to the market and general benefit. At the same time, it also can make the preparation and machining process of the manufacture together, unite CAD, CAM and CAPP, and improve the automation level of flexible machining.CAD NC programming and virtual machining simulation of Side periscope cover terrace die is accomplished in this thesis by UG NX, which, at present, is an advanced mechanical engineering system consisted of CAD, CAM and CAE together in the world.Based upon the new machining technics and high quality NC programming, a new way that carry out the higher efficiency and accuracy machining of the curved surface is given. Details are as follows. Firstly, the machining method of the terrace die is chosen after analyzing the arts and crafts of the curved surface in detail according to its structure characteristic and technical specifications.Then parameterized models of the terrace die and blank are created in UG/CAD environment. On this basis, using UG/CAM NC programming module optimize the processing path, tool path and cutting mode of processing parameters. The gouges between cutting tools and the part are disappeared. Then introduced the UG-based universal post processing techniques and user-based design post-processing techniques, Developed a widely used FANUC CNC system dedicated post processing, Build high precision and efficient NC programs of the part. Greatly increased the machining efficiency and Processing quality in true maching tool. As UG NX is built on a product design environment that is based on process, it can complete the integration from designing to machining, impel the automation and high efficiency of the design and manufacture, and also improve the competitive capability of the enterprises on the international market.
