Machining technology has entered the era of sub micron and nano ultra precision machining, networking manufacturing technology is in the ascendant, and green manufacturing is rising. Digital manufacturing based on CNC machine tools has promoted a new stage of intelligent manufacturing. Technology integration and technology compounding have become one of the most active development trends of CNC machine tools. Nowadays, science and technology in the world are developing with each passing day, and are pregnant with new revolutionary breakthroughs. Machining technology has entered the era of sub micron and nano ultra precision machining, networking manufacturing technology is in the ascendant, and green manufacturing is rising. Digital manufacturing based on CNC machine tools has promoted a new stage of intelligent manufacturing. Technology integration and technology compounding have become one of the most active development trends of CNC machine tools

China still has a long way to go to become a powerful machine tool country. When exploring the future trend, don't just think that foreign new machine tool products are the trend, knowing what it is and not knowing why. From the general trend of social and economic development, as a production tool and energy consuming product, the focus of product innovation in the next few years can be summarized as the following four aspects:

(1) ecological machine tools. Green manufacturing is the premise of sustainable development

what is the proportion limit of green ecological machine tools σ Is p the maximum stress representing the proportional relationship between metal stress and strain (i.e. according to Hooke's law)? The vision of a green and ecological machine tool should have the following characteristics: the main parts of the machine tool are made of recycled materials, the weight and volume of the machine tool are reduced by more than 50%, the power consumption is reduced by 30%~40% through measures such as reducing the mass of moving parts and reducing the idling power, and the various wastes in the use process are reduced by 50%~60%, so as to ensure a basically pollution-free working environment, and the materials of the machine tool after scrapping are 100% recycled

the new concept of green ecological machine tool is to reduce the weight of the machine tool, save materials, and reduce the energy consumption of the machine tool

the machine tool must embody the evaluation standard of energy saving and emission reduction and overall benefit oriented. For many years, machine tool capability indexes such as precision, speed and power have been the main goals of machine tool products. At present, under the pressure of preventing environmental deterioration, industrial production needs to reduce the negative impact on the environment in an all-round way. The development direction of machine tools should also change from improving capacity indicators to improving efficiency indicators, so as to obtain more output with less input

the main ways to make machine tools green are: adopting new structures and materials to reduce the mass of moving parts and achieve energy saving; Dry cutting and MQL are adopted to realize emission reduction. Pay attention to smooth chip removal path and rapid heat removal, so as to ensure that the machine tool will not be thermally deformed due to dry cutting and MQL, which will affect the machining accuracy

(2) smart machine tool. The intellectualization based on Internet and computer technology is the embodiment of the further extension of human brain power by machine tools. Intelligentization can improve the stability and reliability of the machine tool. Smart machine tools can monitor their own status with the help of various sensors, analyze the information about machine tool status, processing process and surrounding environment by themselves, and then take countermeasures to ensure optimal processing. In other words, machine tools have evolved to send messages and think and adjust themselves. For example, active vibration suppression that can reduce vibration, intelligent thermal barrier that can control thermal displacement, intelligent safety barrier that can prevent component collision, voice prompt and SMS notification, and help select cutting parameters according to machining requirements

smart machine tool is actually a complete processing system, and the essence of the processing system is the networking and intelligence of the manufacturing system

system dynamic optimization. After integrating the relevant process and equipment knowledge, the model is built to optimize the dynamic performance of the system

equipment adaptation. Develop new measurement methods, models and standards, monitor the state of the machine tool in the running state, and carry out self diagnosis and error compensation with the help of measurement, sensing and real-time analysis, so as to improve the working performance of the machine tool

express the most sincere thanks; I would like to express my heartfelt thanks to Shenzhen stock exchange for providing us with a good investment and financing platform and for adopting the new generation CNC system. The interface and data format compatible with STEP-NC make the machine control based on CAD model run seamlessly

a method for directly measuring tool wear and workpiece accuracy during machining

(3) customization. Changing from mass production to mass customization is the general trend of manufacturing industry, and the machine tool industry is no exception. Being a good craftsman and creating value for users is not empty talk. Users produce different products and have different requirements for machine tools and equipment. For example, the goal of the compound machining machine tool is that a complex workpiece is processed on one machine tool. Different workpieces have different processes and processing methods, and the configuration of the compound machine tool should be different. It can be predicted that a considerable number of enterprises that only focus on the production and sales of traditional general-purpose machine tools will be gradually replaced by competitors that provide users with modular, reconfigurable and flexible comprehensive solutions

in order to strive for greater sales highlights, foreign companies have applied the concept of service economy to the sales of machine tools. The traditional machine tool maintenance service has been impacted differently, resulting in great changes. The traditional maintenance service of CNC machine tools has been expanded to help users create value, improve productivity, and achieve the promotion of green building, which will be beneficial to the market utilization of polyurethane insulation materials to a large extent to maximize benefits. Designing solutions for customers is the basic strategy for common development

we should combine service economy with manufacturing and sales, and change the operation mode of the machine tool industry. Machine tool enterprises must maintain their competitiveness by combining technology, service, management and cost. Technology determines strength, service determines advantage, and management and cost determine benefit. What users need, enterprises should focus on the needs of users, especially grasp the forward-looking needs of the market, meet the new changes in the market, form a comprehensive service capacity, provide complete sets of finished products and comprehensive solutions, and gradually realize the undertaking of general contracting projects

(4) combination of soft and hard. Traditional machine tool manufacturers usually do not provide software products when selling machine tool products. Even for CNC machine tools, the software of their CNC system is embedded in the CNC system by the system supplier, not provided by the machine tool manufacturer. With the increasingly complex shape of the machining object, the continuous expansion of the function of the NC machine tool and the gradual increase of the number of control axes, software support must be relied on to give full play to the maximum benefits of the machine tool and ensure that users can process with the highest process safety and efficiency

in today's interconnected logistics, machine tools are not only a production equipment, but also a contact in the factory network. In the network, the machine tool can establish contact with the production management system, tool and material management system, and even with the machine tool and tool suppliers to automatically deal with problems in production
