What Is a Flexible Factory?

In fact, flexible manufacturing modes exist widely, such as customization, which is a consumer-oriented production mode that is opposed to the traditional mode of mass production. In flexible manufacturing, the test is the response speed of production lines and supply chains. For example, the emerging models of "C2B" and "C2P2B" in the field of e-commerce reflect the essence of flexible manufacturing. The first aspect is the ability of the system to adapt to changes in the external environment, which can be measured by the degree to which the system meets the requirements of new products; the second aspect is the ability of the system to adapt to internal changes, which can be used in the case of interference (such as machine failure), and the productivity of the system Measured against the expected productivity value without interference. "Flexible" is relative to "rigid". The traditional "rigid" automated production line mainly realizes mass production of a single variety.

Flexibility can be expressed in two aspects

One aspect refers to the flexible response capacity of production capacity, that is, the small batch production capacity of machinery and equipment:

The advantage is that the productivity is very high, because the equipment is fixed, the equipment utilization rate

(1) The machine is flexible, and the system's machine equipment has the ability to process different parts as the product changes;

(2) Process flexibility, the system can determine the corresponding process flow based on changes in processing objects or changes in raw materials;

(3) The product is flexible. After the product is updated or completely changed, the system not only has the ability to inherit and compatible the useful characteristics of the old product, but also has the ability to produce new products quickly and economically;

(4) The production capacity is flexible. When the production volume changes, the system can respond in time and operate economically;

(5) Flexible maintenance, the system can use multiple methods to query and handle faults to ensure normal production;

(6) Expansion flexibility, when production needs, it is easy to expand the system structure, add modules, and form a larger manufacturing system ^[1]

In 1967, the British Molins developed the "System 24" for the first time based on the basic FMS concept proposed by Williamson. Its main equipment is a multi-process CNC with six modular structures

1. Can automatically control and manage the processing of parts, including automatic control of manufacturing quality, automatic diagnosis and processing of faults, and automatic collection and processing of manufacturing information;

2. Through simple software system changes, multiple parts of a part family can be manufactured;

3, automatic control and management of materials (including workpieces and

Computer Aided Design

In the future, the development of CAD technology will introduce an expert system to make it intelligent and can handle various complex problems. One of the latest breakthroughs in current design technology is photosensitive stereoforming technology. This new technology uses CAD data directly and uses a computer-controlled laser scanning system to divide the three-dimensional digital model into several layers of two-dimensional sheet-like graphics. Graphically scan the liquid level of the photosensitive resin in the pool optically. The scanned liquid level becomes cured plastic. In this cyclic operation, scanning is performed layer by layer, and the sheet-shaped cured plastic layered and formed are automatically bonded together. You only need to determine the data, and you can make an accurate prototype within hours. It helps speed up the development of new products and new structures.

Fuzzy control technology

The practical application of fuzzy mathematics is a fuzzy controller. The recently developed high-performance fuzzy controller has a self-learning function, which can continuously acquire new information and automatically adjust the control amount during the control process, which greatly improves the system performance, especially the self-learning method based on artificial neural network. It has caused great concern.

Artificial intelligence, expert system and smart sensor technology

so far,

FMC will become a popular technology for development and application

This is because FMC invests much less than FMS and has similar economic benefits, making it more suitable for small and medium-sized enterprises with limited financial resources. Many foreign manufacturers have listed FMC as a priority.

Developing more efficient FML

The demand for FML from many varieties and large-scale production enterprises, such as automobiles and tractors, has caused great attention from FMS manufacturers. Low-cost dedicated CNC

Through the research and construction of the flexible center, the computer application ability and technology processing level in the development of large-scale antenna systems have reached domestic leading and international levels in the early 1990s, providing a strong guarantee for the completion of key research tasks.

Cell production

Compared with the traditional mass production method, the cell production method has two characteristics, one is the small scale (

Flexible production line is a production line that combines multiple adjustable machine tools (mostly special-purpose machine tools) and is equipped with automatic conveying devices. It relies on computer management and combines multiple production modes, which can reduce production costs and make the best use of it.

Flexible manufacturing technology is a novel concept model and new development trend to realize the future factory, and it is a strategic measure that determines the future development of manufacturing enterprises. At that time, intelligent machines and humans will be integrated with each other to fully and flexibly coordinate all activities of the company's production and operation, from receiving orders to production and sales.

Flexible manufacturing as a scientific "philosophy" of modern industrial production and an advanced model of factory automation has been recognized internationally. It can be considered that flexible manufacturing technology is based on automation technology, information technology and manufacturing technology. China s independent engineering design, manufacturing, and management processes, supported by computers and software, form a complete and organic system covering the entire enterprise to achieve global dynamic optimization, overall high efficiency, and high flexibility. And then win the competition of intelligent manufacturing technology. As the cutting-edge technology for the development of manufacturing automation technology in the world today, it provides a magnificent blueprint for future institutional manufacturing factories and will become the main production model of institutional manufacturing in the 21st century. It implements the division of virtual networks according to ports, MAC addresses, applications, etc., which effectively controls the broadcast traffic of the internal network of the enterprise and improves the security of the internal network of the enterprise ^[1] .

In reality, there are many different types of networks, some supporting TCP / IP and some complying with the OSI standard protocol. The corresponding layer protocols of each machine are different. For which layer to implement the connection, corresponding network interconnection equipment is required.

In layman's terms, Layer 2 switching refers to a multi-port switch set line, that is, a network switch. The purpose is to replace the traditional hub and improve the effective bandwidth of the network. Mainly used in LAN. Bridges (hubs) are used between different or the same types of LANs, which are data link layer devices from the protocol layer, but they are still a method of network connection because the LAN IMP itself does not have a network layer, only at the host site Only at the network layer or provide network layer services. Unlike bridges, gateways work at the network layer level. This gives more flexibility. For example, translating addresses between very different networks, etc., but this also causes the speed of the gateway to be very slow. Therefore, the gateway is generally used for the connection between the WANs or the interconnection between the LAN and the WAN. With the evolution of the network and the emergence of 100M high-speed Ethernet, the delay caused by routers in communication between network segments has become a bottleneck in network information transmission. The emergence of Layer 3 switching technology has solved the bottleneck of network information transmission between subnet segments in a large-scale local area network, replaced expensive routers, and became a practical and economical networking technology.
