| Being economic globalization going a step further being deepened by , science and technology are competing, Domestic of key manufacturing engineering easy to damage of introducing key equipment by he homeland-Reverse Engineering(RE), Already become one of the key factor breaking the abroad technology restricting and sealing off, increasing economic efficiency , consolidating national security. Especially on high-tech industries of our country at present, harm of a part already of introducing equipment core digitization build, rapid develop, already become one important technology means. This paper introduces Reverse Develop of key guiding device of aero-engine mainly. By numerical control measurement and data processing technique Build 3D models, Be based on the characteristic of Investment-casting, Again, structure casting rough , Investment-casting process and Investment-casting waxen mould, Choose proper wax type material, constitute right manufacturing process and install-nip means, by machine work and smooth complete technology, speediness machining high-accuracy demands waxen mould of Investment-casting of guiding device, achieve fleetness develops and small batches of this kind part . There for , the thesis has carried out mainly as follows job1. According as measurement and their data processing technique, accomplished some guiding device's 3D building model and building model of Investment-casting press mould.2. Discussed the composition and function of Investment-casting waxen mould material, chosen the wax type which is suitable Investment-casting and machining work, and tried to find out relevance characteristic property parameter of turning and NC machining, design install-nip fashion of Investment-casting waxen mould, worked out the scheme processing of machining.3. Discussed the characteristic and method of UG-CAM system the complicated surface numerical control programming.4. Integrating common and NC machining means, smooth complete technology, speediness machining high-accuracy demands waxen mould of Investment-casting of... |
