A Flexible Manufacturing System Is For Flexible Production-www.cpew.cn

UnCategorized With the advent of work station automation and the use of .puters to direct the tasks of machines on the production line, the flexible manufacturing system has been created. A group of .puter guided machines in a given work area can be used to create parts or products by following instructions sent to them from controllers. Usually each work station on the production line has its own controller, but that is not always the case. Having a series of controller-directed machines that make up one production line is a definite step toward the fully automated production line, where the machines do all the work, not just specific tasks at specific work stations. The real flexible manufacturing system is a definite .bination of different types of automation, SCARA, articulated, Cartesian, or Delta. The types of automation to be included here is dependent on the tasks that have to be done on the production line, and in what order these tasks are to be done. This order of work will be dictated by the product or part that is being produced. A very prominent characteristic of this flexible manufacturing system is the ability of the machines to .municate with each other. Basic to the .munication is the notice that one work station may have .pleted its task with a certain part that is going through the process on the line. Once the task is .pleted, the machine must make the next machine on the production line aware of that fact, so that the cycle for the next work station can start with out delay. All of the instructions for the flexible manufacturing system are programmed into the controllers in advance. Increasingly, machines on the production line are being programmed by graphical presentations on .puter screens, that is, graphical .puter interfaces. This allows the programmer to follow the machining operation and specify desired operations without the need for statements in a programming language. Robots have usually been programmed by so-called teaching, where the robot is physically led through a sequence of movements and operations; the robot remembers them and carries them out when requested. Sometimes the series of steps that occur on the production line, occur at timed intervals. One work station .pletes its task after 30 seconds, and the next work station is scheduled to start its task at 35 seconds. The .munication that occurs from one machine to another on the production line usually occurs on the high-speed intranet that has been set up for the business. This is a network that operates only within the bounds of the .pany, it connects the workstations of the business together. Historically, the machine centers on a production line were static, which means they could only perform one task, and they had very little variation in what they could do. With the flexible manufacturing system it is possible to re-program the machines to perform a wide variety of tasks. The machines that are located at the work stations are not locked into a single position to do any task. These machines can be moved to another location on the production line and do an entirely different task than they have done previously. One of the driving forces of current manufacturing is not the ability to produce a large number of one style of product so as to satisfy the demand of a given mass market. The driving force for manufacturing to be successful is to be as flexible as possible in the manufacturing of products, and as responsive as possible to fulfilling orders and adapting to change. The personalization of products is getting closer to a reality. The manufacturer that has the ability to produce products that are customized to the demands of customers will be further ahead. The flexible manufacturing system will help deliver the requirements that customers have for customization. Customizations of products can be delivered in more than one type. The variations in these types of customizations may have a bearing on the programming that is done for the controllers on the production line. There may be a variation in the material that is used in manufacture or there may be certain steps of the manufacturing process that may not be required for some products, but are required for others. It is important to take into account the possible demands of the marketplace when designing the flexible production line. Success in mass customization manufacturing is achieved by swiftly reconfiguring operations, processes, and business relationships with respect to customers’ individual needs and dynamic manufacturing requirements. It is thus critical to develop a manufacturing system that will achieve this goal. Production lines are usually considered to be relatively rigid and unable to keep up with changes in product design, even though there are demands from customers to do this. A production line at one of these manufacturers should be made so that reconfiguration is possible from the physical standpoint. There are already some successful attempts by manufacturing enterprises to move in this direction. The manufacturing system of Motorola pagers has successfully developed this type of manufacturing production line. Basic workbenches on the production line are standardized, with different fixtures, manipulators, and their control codes. Hence, when Motorola needs to produce a new product, the original line can be taken apart and reconfigured to support a new production run easily and promptly. The line conversion requires only a small amount of positional modifications to the basic workbenches, which greatly saves time and costs in the new production line construction. In addition, General Motor’s Michigan Electronic Vehicle assembly factory has been equipped with movable workbenches that can be adjusted efficiently according to manufacturing requirements. This factory can change swiftly to meet new demands; its expandable throughput ranges from 2000 to 100000 per year. There needs to be a definite choice between the tendency to mass produce products and the tendency to mass customize products when designing a flexible manufacturing system. About the Author: 相关的主题文章:
