Domestic machine tools for processing spiral bevel gears mainly rely on imports. For example, Shanghai Machine tool Domestic machine tools for processing spiral bevel gears mainly rely on imports. For example, Shanghai Machine tool Factory has imported five Y2250 machine tools, which are very expensive, with domestic import prices ranging from US $80 to US $1.2 million, and often manufacturers take parts with them to order and entrust programming. the processing technology is controlled by others.
The research onmachining in China is still focused on “Gleason” machine tools. This kind of machine tool has many parameters, difficult to operate, complex debugging, and the calculation results of machine tool control parameters depend to a large extent on the experience and technical level of the calculator, which limits the application and development of spiral bevel gears.
Although there are six domestic manufacturers of CNC gear machine tools, their CNC systems are still mainly based on the introduction of Fanuc and Siemens companies. Due to the characteristics ofprocessing, these general CNC systems can not give full play to their performance, CAD and CAM can not achieve integration, the price is also expensive. If we rely on imports, the price of machine tools is more expensive, and they also achieve a technical blockade, which is extremely disadvantageous to the application of gear machine tools in our country.
Therefore, according to the characteristics of bevel gear machining, we need to have our own set of numerical control system. Using our successful development experience in numerical control, we put forward the idea of developing spiral bevel gear numerical control system. In order to research and develop the numerical control system, this paper studies and discusses the NC machining theory of spiral bevel gears, which is helpful to apply and popularize CNC gear machine tools, improve China’s competitiveness in the world, and promote the development of China’s economy. It has a wide application prospect.
