文摘NC machining of parts and components is developing in the direction of automation and intelligence.In addition,the automatic production line puts forward higher requirements for the overall layout,technological process and production tempo.The layout and simulation of the production line can more directly reflect the problems that may occur in the operation of the production line,and solve these problems through scientific methods.This project uses VisualOne software to simulate the operation of the intelligent manufacturing production line,which can directly find the existing problems in the layout of the production line and the process of the craftsmen,and optimize the layout of the production line.In addition,it can provide reliable support for the equipment procurement and on-site construction of the intelligent manufacturing automation production line in the later stage.
文摘The rapid development of China's automobile manufacturing industry promotes the continuous transformation and upgrading of China’s automobile industry. From the productive labor-intensive manufacturing to today’s intelligent robot application, it reflects China’s strong industrial manufacturing strength. Automobile manufacturing industry not only has the characteristics of technology intensive industry, but also has the characteristics of labor-intensive industry. And in the production process, there are strict requirements for the accuracy and quality of parts manufacturing. Industrial robots can efficiently complete the welding, handling, assembly, spraying and other application tasks in automobile manufacturing, improve the degree of automation in automobile manufacturing industry, and change the traditional pattern of automobile manufacturing.
文摘In the current environment of continuous innovation and integration of information technology manufacturing technology, it provides a broad space for the application of intelligent manufacturing technology in manufacturing industry. In this paper, the concept and components of intelligent manufacturing technology are briefly described, and the current development trend of intelligent manufacturing technology and standardization system is analyzed. It is hoped that intelligent manufacturing technology can effectively promote the rapid development of manufacturing industry.
文摘The 5th Meeting of Sino-German Standardization Sub-working Group on Intelligent Manufacturing/Industry 4.0 was held in Hangzhou,capital of east China’s Zhejiang province from December 3 to 4,2017,bringing together over 90 representatives of both countries.
文摘Intelligent manufacturing as the future development direction of industrial manufacturing, the application of automation technology of mechanical design and production can not only improve production controllability, reduce human intervention error, but also can collect more and accurate design and production data, to realize the automation and intelligence of design and manufacturing. In the future development of mechanical design and automation technology, it is necessary to focus on product data collection and sharing, energy conservation and environmental protection, the introduction of artificial intelligence and other directions. Only by combining the organic combination of traditional mechanical design and automation technology and intelligent manufacturing, can we promote Chinas machinery manufacturing industry to glow with new vitality and achieve technical breakthroughs, and promote the healthy development of Chinas industrial manufacturing industry.
