Research On The Wheel Surface NC Processing System

Railway transportation is one of the important components of the traffic in our country, and plays a very important role in national economic construction. At present, the railway traffic of our country cannot catch up with the need of fast-developing economy. It is very essential to raise train speed for alleviating transportation and bringing about economy progress. One main reason that restrains train from raising speed is relatively backward railway maintaining equipment especially train wheel-repairing equipment. Most wheel tool is not numerical control tool. The labor intensity is heavy, and the repairing precision is low. Foreign advanced numerical control equipment is expensive and inconvenient to maintain. So, It is imperative to develop the high-performance numerical control wheel tool independently. Research has been made on the train wheel tool combining the actual project in this paper. The following research is made in this paper: 1.According to the need of numerical control processing ,the mathematics model of train wheel has been established.2.According to the feature of the surface of the train wheel,the on-line measure technology ,measuring effect and measuring error of the NC train wheel are studied. 3.The numerical control processing method of the wheel surface is studied; The tool-path, process, tool and error compensation are studied too. 4.The safety guarantee technology is studied.5.The control system of the train wheel maintenance is developed based on HuaZhong CNC system according to the need of the wheel surface maintaining.
