摘要
柔性制造系統(tǒng)（FMS）是一種形式的柔性自動化，把若干個機床聯(lián)系在一起的一個材料處理系統(tǒng)，該系統(tǒng)的所有方面的控制都有一個中央電腦完成。這一系統(tǒng)減少了安裝或轉(zhuǎn)換時間和便利的生產(chǎn)小數(shù)目的產(chǎn)品。 轉(zhuǎn)移的重點是從大規(guī)模生產(chǎn)的少數(shù)產(chǎn)品轉(zhuǎn)化為車間作業(yè)的環(huán)境中定制訂單產(chǎn)品。The shift in emphasis is from mass production of a few products to a job-shop environment in which customized orders are manufactured. Automation allows for better quality and scheduling, rapid changes in product lines, and lower inventories and costs .自動化設計具備更好的質(zhì)量和調(diào)度能力，使生產(chǎn)線可以快速變化，降低了庫存和成本。
柔性制造系統(tǒng)具有靈活性的特點，他們的裝置控制器和中央控制計算機可以復制出新的零件或改造舊零件。 They can also often make a number of different types of parts at the same time.他們也可以在同一時間內(nèi)作出多項不同類型的零件。 然而，這種靈活性是有局限性的，以車軸為例， However, this flexibility is limited to a certain family of parts, for example, axles.A general goal for designers is to increase flexibility, and advanced flexible manufacturing systems are more flexible than the earlier ones.總體目標是增加靈活性，因此柔性制造系統(tǒng)相較于從前的制造系統(tǒng)更具有靈活性。
總體來說，柔性制造系統(tǒng)具備以下優(yōu)勢：更大的勞動生產(chǎn)率：只需要具有專門的教育和技能的較少的工人。更大的機械效率：產(chǎn)品的生產(chǎn)需要較少的及其樓面面積和空間。質(zhì)量的提高：由于上線測試，使之能即時反饋信息和調(diào)整制造過程。增加了系統(tǒng)的可靠性：智能化，自診斷控制，為確定硬件問題減少了時間。減少了部分庫存：柔性制造系統(tǒng)的一個主要特點就是柔性制造能力，在經(jīng)濟上容納不同的一批大小、甚至下降至運行一個單一的部分。改進調(diào)度能力：容許這些快速反應的變化，在產(chǎn)品設計和生產(chǎn)調(diào)度，有能力，以符合剛剛在時間調(diào)度，并減少前置作業(yè)時間。 適應性的CAD\CAM行動：數(shù)碼規(guī)格開發(fā)的電腦輔助設計/電腦輔助制造系統(tǒng)可以作為投入的過程。
作為一個柔性制造系統(tǒng)，必須具備的關鍵要素有：計算機控制，自動化材料處理能力，工具處理能力。柔性制造整合了自動化制造的概念：計算機數(shù)值控制個別機床，分布式數(shù)字控制的制造系統(tǒng)，自動化物料處理系統(tǒng)，成組技術。當這些自動化流程，機器和觀念聚集在一個集成的系統(tǒng)，就是所謂的柔性制造系統(tǒng)。在柔性制造系統(tǒng)中，人類和計算機發(fā)揮主要作用。

Abstract
A flexible manufacturing system (FMS) is a form of flexible automation in which several machine tools are linked together by a material-handling system, and all aspects of the system are controlled by a central computer.
Flexible manufacturing systems are flexible in the sense that their device controllers and central control computer can be reprogrammed to make new parts or old parts in new ways. They can also often make a number of different types of parts at the same time. However, this flexibility is limited to a certain family of parts, for example, axles. A general goal for designers is to increase flexibility, and advanced flexible manufacturing systems are more flexible than the earlier ones.This system reduces setup or changeover times and facilitates the production of differentiated products in small numbers. The shift in emphasis is from mass production of a few products to a job-shop environment in which customized orders are manufactured. Automation allows for better quality and scheduling, rapid changes in product lines, and lower inventories and costs.
Greater labor productivity. Fewer workers requiring specialized education and skills. Greater machine efficiency. Fewer machines, less floor space and less space for operator movement. Improved quality. Less waste because on-line gauging allows immediate feedback and adjustment of the manufacturing process. Increased system reliability. Intelligent, self-diagnosing controls decrease the time required to identify and correct hardware problems. Reduced parts inventories. A key feature of flexible manufacturing is its ability to economically accommodate different batch sizes - even down to a run of a single part. Improved scheduling capabilities. These allow rapid response to changes in product design and production scheduling, the ability to conform to just-in-time scheduling, and reduced lead times. Adaptability to CAD/CAM operations. The digital specifications developed by Computer Aided Design/Computer Aided Manufacturing systems can serve as inputs to the process.
The key elements necessary for a manufacturing system to qualify as an FMS are as follows:Computer controlautomated materials handling capabilityTool handling capabilityFlexible manufacturing integrates several automated manufacturing concepts:Computer numerical control (CNC) of individual machine toolsDistributed numerical control (DNC) of manufacturing systemsautomated materials handling systemsGroup technology (families of parts).When these automated processes, machines, and concepts are brought together in one integrated system, an FMS is the result. Humans and computers play major roles in an FMS.
Keywords: flexible manufacturing system, flexible, flexible manufacturing ability, Computer controlautomated materials
