Intelligent Open CNC Technology I. Technical Overview Industrial countries around the world through the development of CNC technology, a CNC machine tool industry, prompting machinery industry entered a new modern stage of historical development, and thus the structure of the national economy has brought great changes. CNC machine tools is not only an important basis for mechanical and electrical industrial equipment, automotive, petrochemical, electronics and other pillar industries, the primary means of production modernization, NC is the third industrial revolution the world is an important content. Output of CNC machine tool industry itself far less automobile, chemical and other industries, but the high-performance CNC machine tools to the manufacturing industry has brought the benefits of the high rate of production growth and modernization is to promote national economic development of the huge source of power. In particular, numerical control technology in the manufacturing sector expansion and extension of the role and the resulting ripple effect of radiation on the mechanical manufacturing industry sufficient structure, product structure, specialized division of labor, machining methods and management models, the production of social division of labor, business operational mechanism of profound change. In CNC machine tools are widely used in the numerical control technology, is a machining process using computer control information in a variety of digital computing, processing, and high-performance drive units through the implementation of mechanical components for automatic control of high-tech. The current equipment has been used a lot of CNC machining technology, the most typical and most widespread is the application of CNC machine tools. The machining process of the diversity and complexity of machining parts, CNC machine tools to the specifications, types and properties very different from the complexity of the control parameters, debugging complicated operation, so in general will continue the rapid development of computer technology and its architecture , the modern automatic control theory and modern technology to a new generation of power electronics CNC machine tools, we should emphasize them with open and intelligent features. 1. Open Requires a new generation of CNC machine tool control system is an open, modular architecture, its features are: Modular elements in the realization of the system at the same time, there should be standardized between these elements can be provided by the different elements of the buyer free to combine, which can easily constitute a complete system. As follows: - Elements of the system should be modular, while the interface between the modules must be standardized; - System software, hardware configuration should be transparent, portable; - System should have the continuous upgrade capability. At the same time the mechanical structure of a new generation of CNC machine tools also should be open, should be characterized by: - Function module components using the machine; - A technology plan, processing database to users; - Use of information technology will be a reasonable allocation of social resources, manufacturing machinery manufacturing industry gradually establish a perfect virtualization and network-based advanced manufacturing systems, machinery manufacturing resources to be used efficiently, to reduce costs, improve quality, the purpose of reducing manufacturing cycle. 2. Intelligent The so-called intelligent control system, is smart with anthropomorphic features, the numerical control system with simulation, extension, expansion of the intelligent behavior of the knowledge processing activities, such as self-learning, adaptive, self-organization, self-optimizing, Zi calm, self-recognition from planning, self-healing, self-reproduction. Through the intelligent CNC machining accuracy and efficiency of physical testing, modeling, feature extraction, processing system automatically senses the internal state and external environment, to quickly make the best goal of the intelligent decision-making, feed rate, cutting depth , coordinate movement, spindle speed and other parameters in real-time control, so that the processing machine at its best. The current NC system functionality required not only high performance (high-speed, high precision and high reliability), but also includes many smart features, such as the processing of motion planning, reasoning, decision-making ability and perception processing environment, manufacturing, network communication capacity (including the interaction with others), intelligent programming, intelligent databases, intelligent surveillance. Practice has proved that these intelligent technology, also used in the 21st century, the adjustment of a new generation of CNC machine tools,
