Output of CNC machine tool industry itself far less automobile, chemical and other industries, but thehigh-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. IntelligentThe 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 asself-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, use and maintenance of all aspects, so that human intervention greatly simplified, to apply "smart" technology, human machine interface for packaging, to make full use of natural language, artificial Windows interface and simple operation, so that adjustment of the machine, use and maintenance tends to be "fool."Second, the status quo and development trend of domestic and foreign1. Overseas DevelopmentThroughout the history of the development of numerical control technology, is easy to see the development of numerical control technology step through the development of computer technology continues to develop, from 1956 to the present, has gone through four stages as follows:In 1956 -1974, the era of proprietary hardware NC;1975 -1989, the special computer numerical control era, that era of the microprocessor NC (μ PC);In 1990 -1995, BASIC PC's CNC times;Since 1996, started the whole PC open a new stage of intelligent CNC.The first three stages of the NC devices there are the following limitations: --- Not free to select the information from the information network;--- Not open architecture, user interface imperfections, machinery manufacturers and users can not independently numerical control system according to crop needs, the user's own technical know-how is not easy to integrate into, and create their own brand names;--- Can not fully utilize the existing resources of common software;--- Can not be free access to the external condition information;--- Architecture many, is not conducive to mass production, improve reliability and reduce costs, reduce the market supply capacity and competitiveness, while limiting the development of numerical control technology.In recent years the United States, the European Community, Japan and other countries have taken measures, a lot of money, the joint of the plant, or even more countries to study a new generation of numerical control systems, from the foregoing information, the world is in the NC Technology All PC CNC open architecture platform, turning the era, the turn is adapted to computer technology, information technology, network technology, the inevitable result of technological development.As modern machinery industry gradually to flexible, integrated, intelligent direction, so must be stressed that a new generation of numerical control technology to have an open and intelligent features. Developed countries have taken measures in recent years, lots of manpower and financial resources to organize a new generation of superior forces and open architecture CNC with intelligent features technology development and research, including the United States of NGC and OMAC plan, the EC OSACA plan, OSEC plans.CNC machine tool mechanical structure is more inclined to "open", to meet the diverse needs of the modern machinery for processing, a new generation of CNC machine tools has the following characteristics:(1) according to the modular machine structure, the principles of design and manufacturing series in order to shorten lead times, best meet the needs of the user's process.(2) As many parts of NC machine tool quality indicators continue to improve, gradually increase the variety of specifications, a more substantial mechanical and electrical integration, functional parameters of the increasingly numerous and so dedicated to supporting a variety of CNC machine features are fully commercialized, to build a competitive machine tool plant created the conditions.(3) to the users, CNC Machine Tool Plant of the developed countries areactively building completely open product sales service system. Part to establish an open laboratory, establishment of self-service CNC machine operator and maintenance training center.(4) using information network technology to a variety of manufacturing resources in society were based on the rational combination of processing tasks and call the 21st century advanced manufacturing technology development trend, the world's countries are active in research in this area.(5) artificial intelligence technology in the promotion and application of CNC technology. With the continued penetration in the computer field of artificial intelligence and development of the intelligent CNC system development. In the new generation of CNC system and servo devices, the use of "evolutionary computation" (Evolutionary Computation), "Fuzzy Systems" (Fuzzy System) and "neural networks" (Neural Network) and other three new control mechanism, the performance greatly increased. This high-performance intelligent CNC system not only has the automatic programming, feedforward control, adaptive cutting, self-generating process parameters, motion parameters of dynamic compensation and other functions, more features are taken into account operational factors used in the very present friendly interface.The current principle of fuzzy control systems, and CNC EDM with aself-learning, self-established mathematical model, high-performanceself-tuning parameters of the servo drive CNC machine tools and existing products in the market with a strong competitive edge.2. Current Situation and Development of numerical control technology gap China's CNC technology, in the "Eighth Five-Year" key in order to seize the opportunity to own the copyright for the proposed target to platform-based development strategy, but also in the research process, aiming or adjustment to the development of PC-based route , and thus the formation of two platforms, developed four basic systems, central China and the ChineseI-I-NC-specific template is embedded into a single general-purpose PC NC system bodies, space and the blue sky I-I-is embedded in the PC, being composed of CNC multi-machine CNC system, the formation of the typical structure of front, the domestic unit also has developed other open architecture system.However, in general terms, but only at the initial stage, although different systems direction to the PC platform, but in the concrete implementation of the development there are still some problems. The biggest problem that is open enough, lack of development environment and support measures, as a user easily to the secondary development of the degree of openness is far from being reached, but has considerable technical force of the developer to use, and as able to spread to the general extent of users is not enough.Design by PC-NC system makes CNC's focus from hardware to software, to eliminate the development of the CNC hardware "bottlenecks", which could accelerate the production of useful products. And PC-NC, after all, so that theopen architecture CNC a big step.In the design and manufacture of CNC machine tools, China has started a modular technology, the CNC machining process parameters, tools, system optimization, intelligent adaptive control have been studied, the intelligent control of it lay the foundation for further study, But the work is only the beginning, still in the "fifth" during a series of research and development work, tracking the world's digital technology, to promote the development of numerical control industry.Third, the "fifth" major research objectives and1.
