Implement green processing improve the resource utilization
Through chain link fence vigorously promote green processing, improve resource utilization, reduce the negative impact on environment, improve the machining of man-machine friendly, realize the machining process of high quality, high efficiency, low consumption and clean, make enterprise benefit and social benefit coordination. 1, virtual manufacturing. Virtual manufacturing (figure 1) may realize chain products processing, working process and assembly process, remove process, recycle process simulation, can effective evaluation of economy, functionality, product within the whole life cycle of environment influence, energy and resources utilization, and provide basis for the product design improvement, Can improve the quality of product design, reduce design link flaws, optimize product performance, Can improve process planning and optimization of process manufacturing qualityŁ» rationality, Realize flexible processing and agile manufacturing, reduce lead-time, reduce production cost. 2, green manufacturing process. In the product manufacturing process, the traditional technology as the foundation, vigorously promote saving resource consumption of green fence technology, namely in mechanical manufacturing process, the optimal machining process scheme, achieve reasonable utilization of resources, reduce the cost of parts manufacturing, minimize the negative impact on environment pollution. (1) the application of dry processing. Now such dry dry milling process is being widely used, it simplifies the chain link fence process, reduce cost and eliminate the coolant brings pollution and recycling of waste emission problems, such as green machining process. It not only confined to the dry milling, also cast can be extended to other aspects of machining tools, but require higher heat-resistance, wearability, requires high-speed cutting machine, chain cooling device, aspiration. (2) development of cutting technology is less. In a hot-working process application process simulation technology, to determine the optimal parameters optimized scheme, forecast and machining process and prevent the possible measures, which can effectively control and reduce bad piece of fur limits.but. In the process link of manufacture of high speed cutting technology advanced, shorten processing time and improve production efficiency, effectively guarantee the quality of parts processing. (3) using new tool materials. Promoting coated tools and tools, cutting tool wear and improve efficiency, especially for the complex and expensive material is to reduce fence the abrasion tool material consumption and production cost is an important way. (4) waste recycling attention. Through two ways to reduce the waste of environment impact: one kind is to chip, such waste recycling waste, another kind is to return the product components as a revision of the chain link fence raw material production again. Enterprise value after recycling waste products, achieve a closed cycle of green manufacturing mode. (5) improve machining flexibility. The processing system by enterprises in the 1960s, the old machine and machining centers, numerically controlled machine tools, etc, and through a lot of FMS is chain equipped with advanced numerical control equipments and optimized configuration of resources, improve the whole processing machine, flexible, flexible operation flexibility. Processing system can realize reconstruction, for new product development and product update with fast response ability and shorten the production cycle, reduce the production cost, and accelerate the link process of green manufacturing enterprises.As a world famous IT consultants, at the end of 2002, after Gartner of different background, different disciplines, long-term research analysts to Gartner summarized management of enterprises will be a far-reaching influence business concept RTE (real-time enterprise). Gartner will be defined as: real-time business fence enterprise is a real through the use of the latest information to actively eliminate its key business process management and implementation of the delay and the enterprise competition. But Gartner only tell us what is, and not told RTE we realize how RTE. Hence everyone, as some retricted chain link fence software company their ERP software plus RTE concept is claimed to be RTE solutions, etc, the traditional ERP system has SFCS (workshop management module, but as the key), yield production technology, project are dependent on production site personnel handmade statistics, analysis and returns. So no matter how do chain in ERP system to realize real-time factory. As the work site, to produce after work? The original material consumption status? Quality status? The equipment running status? Personnel of status? All of these. Factory production site like a black box, return not real-time information, inaccurate, not stable, etc. But link the MES manufacturing execution system filled the gap, make the production site transparent, help achieve real-time manufacturing enterprises. MES Manufacturing Execution System by the American association for the study of Manufacturing AMR in 1990s put forward: Manufacturing (MES), this System are defined as follows: by a group fence of sharing data procedure consisting of, decorate in the production of the site through a special equipment (barcode harvesters, PLC, sensors, I/O, DCS, RFID, PC, etc.) from raw materials to finished product line of the production process real-time data acquisition and control and monitoring System. Through control including chain link fence materials, equipment, personnel, quality, technology and process instructions and facilities, all factories to improve manufacturing competitiveness, and provides a unified system integration platform, such as quality control, document management, production scheduling, equipment management, manufacturing logistics functions. So as to realize real-time information system of the enterprise. MES real-time chain accepted from ERP system work order, BOM, process, supplier, inventory, manufacture instruction, the information such as the production methods, personnel, manufacture instruction issued to personnel, equipment, such as the control layer and real-time feedback, the production and operation of equipment and results, the inventory status and the quality link conditions of the dynamic feedback to ERP system. Therefore MES establish manufacturing enterprise control layer of various equipment, instrumentation, barcode acquisition equipment, PLC and bridge between the ERP system, completely from the sensor to fill the ravine between ERP.(a) the traditional information safety protection methods The traditional fence information safety means simply to protect static information is given priority to, such as JiMaoXin secret code was, etc. This information is in the form of text messages, adhere to the carrier to save. (2) the modern information safety protection methods Because the traditional safety protection chain link fence methods to protect static text information of simple, and cant adapt to the dynamic information protection needs. Modern information safety protection mainly adopts a firewall, waterproof wall, information encryption, preventing electromagnetic leakage means to ensure information from wwrongful appropriation. Used to filter firewall with external information, waterproof wall chain inside information, to prevent transmission of information in encrypt, at the same time before through various means to prevent the physical medium electromagnetic leakage. Through a series of information protective measures can we guarantee of multi-level information security. Through the comparison of traditional information safety protection and link modern information safety protection, we can clearly understand the evolution of information security, information from the static and dynamic information, from single to the protection to the comprehensive protection, the protection from sheer level to the multi-level protection. In recent years, along with the continuous development of fence information security technology in construction, the protection system of multi-level also makes the information system of information is more and more complicated, the protection of information security shift, from the guarantee for the security of the system guarantee information, only guarantee the safety of information system and to chain link fence ensure safety of information, the two complement each other. Ensure safety of five factors: information privacy, usability, integrity, authentication, and can be resisted. Below are five basic elements of information security detailed explanation: 1, the secrecy: refers to the network information are not disclose to unauthorized chain users, the entity or process. Only authorized users to use that information. Confidentiality is based on availability and reliability of network information safety, ensure the important means. Common techniques include: (1) physical security: using various methods, such as physical limits, isolation, masking, control, protecting information disclosure. link (2) prevent eavesdropping opponents: patent cannot receive the useful information. (3) anti-radiation: to prevent the useful information in various ways radiating element. (4) information encryption: under the control of the key encryption algorithm for information, encrypt. Even competitors got encrypted information will also because no fence key and cannot read the effective information. 2 and usability: the information in the premise, also ensure the validity and available information. 3 and integrity: refers to the transmission and storage information or data process, make sure that the information or data are not unauthorized tampering chain link fence or can be quickly found after tamper with. 4 and resisted by signature verification, and to judge whether the data during transmission by change. Thus, can realize the data on the sender can send data sending data is clean, the realization of the complete system, resisted demands chain and integrity. 5 and certification: refers to the information can only by the specified user authentication. To ensure the security of information, enterprise above five elements indispensable. According to their own needs, the enterprise information safety protection also have one or several, such as bank system link to accomplish the confidentiality of the information (customer information, to ensure that the data to the usability and integrity (various ATM terminal with bank deposit information exchange data between system) and resisted and can also indispensable authentication validation process and the users password (printed) withdraw slip. For general fence requirement is not high,
