Numerical control technology has been popularized and applied in various industries, especially in mechanical manufacturing industry. There is still a large space for development in the application of numerical control technology in China. Therefore, numerical control technology should be studied and broken through in the next step, so as to provide support for China’s mechanical mold manufacturing industry. On this premise, this paper first expounds the principle of NC machining technology, and then explains its application advantages, scope of application and function one by one. Finally, it puts forward the methods of how to optimize and improve in machining process, so as to provide relevant reference for the development of NC machining industry.展开更多

The system＇s external interfaces are coincident with the corresponding international standards, and the internal interfaces follow the open modular architecture controller （OMAC） agreement. In the research and manufacturing process, object-oriented technology is used to ensure the openness of the HITCNC, and static programming is applied in the CNC system according to the idea of modularization disassembly. The HITCNC also actualizes real-time and unreal-time modules adopting real-time dynamical linked library （RTDLL） and component object model （COM）. Finite state ma- chine （FSM） is adopted to do dynamically modeling of HITCNC. The complete separation between the software and the hardware is achieved in the HITCNC by applying the SoftSERCANS technique. The application of the above key techniques decreases the programming workload greatly, and uses software programs replacing hardware functions, which offers plenty technique ensures for the openness of HITCNC. Finally, based on the HITCNC, a three-dimensional milling system is established. On the system, series experiments are done to validate the expandability and interchangeability of HITCNC. The results of the experiments show that the established open architecture CNC system HITCNC is correct and feasible, and has good openness.展开更多

It will greatly improve the efficiency of production and processing, effectively reduce production costs, accelerate the development of Chinese mechanical processing and make it develop towards the direction of automation and intelligence. Of course, in recent years, the field of machining in China has developed rapidly under the digital technology. Although compared with developed countries, there is still a certain gap and there is a large space for improvement. But as long as we pay more attention to the field of mechanical processing, introduce advanced production and processing technology, explore the problems in the production process with a positive vision and through targeted solutions, we can achieve faster development in the field of mechanical processing.展开更多
