Automation instead of manpower? This is the goal that every factory hopes to achieve. The development of factory automation is a step further to achieve this goal. The generation of FMS (Flexible Manufacturing System) has played an indelible role in promoting the development of factory automation. Flexibe Manufacturing System (abbreviated FMS) refers to a highly flexible and highly automated manufacturing system suitable for multi-variety, medium and small batch production. At present, the increase in product production volume and the intensification of market competition have greatly accelerated the product update speed, which requires product manufacturers to have rapid adaptability. The Flexible Manufacturing System (FMS) and Flexible Manufacturing Unit (FMC) are highly flexible and automated, adapting to the rapidly changing requirements of the product.
FMS overcomes rigid production lines and leads a new era of change
In the 1970s, FMS entered the eyes of people as an emerging term. It overcomes the limitations of traditional rigid automatic lines that are only suitable for mass production, and demonstrates the ability to adapt to multi-variety, small- and medium-volume manufacturing automation.
Flexibility is the biggest feature of FMS, that is, the ability of the system to adapt to the external environment. Automation means minimizing manual operations and even canceling them altogether. FMS marks the traditional machinery manufacturing industry has entered a new era of development and change, showing its strong vitality since its birth.
With the increasing demand for product diversification, low manufacturing costs, and short manufacturing cycles, flexible manufacturing technologies are rapidly developing and mature due to advances in microelectronics, computer technology, communication technology, and mechanical and control equipment. Since 1967, the UK's Molins Company built the world's first FMS. After the 1980s, manufacturing automation entered the era of computer-integrated manufacturing (CIM), and FMS has become the focus of research and development of machinery manufacturing automation in various industrialized countries. From the experimental stage to the practical stage, from the initial simple machining field to the comprehensive field of welding, assembly and chipless processing. So far, a large number of FMSs are in operation in the world, and the number of FMSs in China is also increasing.
In the future, the factory will have FMS everywhere.
FMS production is large, the number of workpieces can be flexibly balanced, and can be produced in 24 hours, which is one of the most basic characteristics of future factory development. FMS is a high-tech integrated technology that integrates computer, microelectronics, control and advanced manufacturing technology. It transforms the traditional rigid production line processing technology, realizes flexible production of multiple varieties and small batches, and fundamentally solves the efficiency of metal processing. Quality issues. FMS's high technology is mainly reflected in the information integration, control integration and logistics integration of the entire production system. It consists of a central computer management control system, an integrated automatic programming system, a three-dimensional warehouse unit, and a logistics system. It has multiple operation control modes, such as automatic material discharge, automatic cutting, automatic processing and automatic storage. The practical application of the system shows that the product quality is improved, the material utilization rate is improved, the production efficiency is improved, a large amount of manpower is saved, the product structure is modified, and the personal safety of the on-site workers is guaranteed.
Therefore, FMS enables enterprises to adapt to changes in market demand faster and better, enhance the competitiveness of the enterprise market, and continuously improve the overall efficiency of the enterprise. FMS can be widely used in the automotive, marine, aerospace, computer and textile machinery industries. It is suitable for the production of multi-variety, small and medium-sized parts families, and is at the workshop level in an integrated manufacturing environment. The most widely used workshop-level production control methods are the centralized control form and the hierarchical control form.
The central control unit belongs to the workshop-level control system and is the core of the FMS control system. It consists of a planning and management server, a CAD/CAM programming computer, and a scheduling and monitoring computer. The main functions include: NC program preparation and management, production planning and management, inventory management, system scheduling and monitoring, and data management of FMS systems.
In the future, the development of the factory is to achieve faster speed and lower cost. FMS integrates these two advantages at the same time. With the rapid development of computer technology, FMS also integrates CAD, mechatronics, artificial intelligence, Artificial neural networks (ANN), CIM and other technologies have become an important part of modern automation systems.
Success stems from practice
In recent years, FMS has become internationally recognized as a scientific “philosophy†of modern industrial production and an advanced model of factory automation. China has also increased the research and development of FMS, because this will not only lay the foundation for China's manufacturing industry to track the world's advanced manufacturing technology, but also further implement the parallel engineering, agile manufacturing, lean production and intelligent manufacturing systems, thus making China's advanced A new level of manufacturing technology has narrowed the gap between China and industrialized countries in manufacturing technology and enhanced their ability to participate in international market competition.
