1、流程操作 Run Time The time it takes to produce one piece.裝置時間和運行時間應考慮周到地保存在每一操作的流程文件之中,而且一般上占總生產交期時間的1020%Setup and run times are maintained discreetly within the routing file for each operation and typically make up about 10-20 percent of total manufacturing lead time.等待時間-指的是材料的轉運,倉存,和工 作中心等待所需的時間.Que

2、ue Time The time the material spends in transit,storage,and at each work center waiting to be worked on.等待時間隨工廠布局,制造工藝和排期作業而定.等待時間是一個非制造時間,在大多數公司,據統計等待時間占到總生產時間的80%90%.我們的目標是盡可能減少甚至消除等待時間以降低成本.等待時間是一種額外的成本,它不能增加產品的價值.Queue time is a function of plant layout,the manufacturing process,and the scheduli

3、ng process.Queue time is non-productive in the manufacturing process.In most companies,it accounts for about 80-90%of the total manufacturing time.The goal is to reduce queue time to as low a value as possible,or even eliminate it.Queue is an added cost.It adds no value to the product.如何使用流程如何使用流程 H

4、ow A Routing Is Used 流程由工程部門開發并應用于公司內很多部門:Routing are developed by Engineering and are used in many departments within a company:工程部-制訂開發新零件的生產工藝.Engineering To develop mfg.processes for new items.2 生產-正確地生產每種產品 Manufacturing To correctly produce each product.車間控制-跟蹤生產制造過程 Shop Floor Control To keep

12、 and Manage Routings(1)工程部決定用最適當的方法和生產資源(工作中心)生產產品.Engineering determines the best methods and manufacturing resources(work centers)to build the product.(2)工程部應和生產部一起開發新的流程.The Eng.Dept.may initially work with Manufacturing to develop new routings.(3)當新的流程在生產中實施時,流程的改變和改進必須用文件存檔使每個人都知道這種變化.As new ro

14、的來說,如果流程是準確的而且被正確地使用,它們將成為公司的溝通網絡中的一個重要環節,從而能更有效地生產產品.In summary,if routings are accurate and used correctly,they will be an important link in a co.s communication network to efficiently produce a product.Routing FileMfg.Item No.Item Master FileMfg.Item No.Master Scheduling&Mat.Planng ProcessesItem

16、rk Centers 一些大的生產地區可以被分為幾個生產單位,例如制造,裝配和檢驗.工作中心產生于細分這些生產單位或部門為更小的區域性單位.在一個依工作性能而排列的生產地區,工作中心一般依機器種類或工藝性能來決定,例如:焊接,機械加工,線路板裝配.在流水作業的生產部門,部門及工作中心應依產品和產品組合來確定.工作中心被賦予一個唯一的號碼和名字,這些號碼和名字反映了工作中心在制造過程中所扮演的角色.每一個工作中心的詳細信息包含在工作中心主文件內.Some large production areas may first subdivided into departments,such as fa

17、brication,assembly and test.Work centers are created by dividing these production areas or depts.into smaller geographic units.In production areas that are functionally organized,work centers are typically defined around types of machinery or around process function,such as welding,machining,or circ

24、 Process30 Machine Specifications103.3.時間標準時間標準 Time Standards 在流程文件中的標準時間有兩個目的:(1)提供交貨周期的基本數據,用于詳細的生產排期中.(2)為評估產品的成本.標準時間應能準確反映實際平均與依工藝改善活動而更新.Time standards within the routing file serve two purposes:(1)Serve as baseline data for rolling up lead times,which are used in detailed production scheduli

26、工作中心的產品,臨時的或其他的流程應提前認可,以維持產品的質量和維持工作中心發貨的準確性.During the process of production scheduling,when a certain work center is overloaded the schedule requires capacity in excess of what is available during the scheduling period,a possible course of action is for process engineering and scheduling to agree

27、on an alternative flow to produce some of the product being across the affected work centers.Temporary or alternate routings should always be pre-approved in order to maintain product quality and in order to maintain the accuracy of work center dispatching.11Unit 9:流流 程程 Routing Lesson 3:生產布局和生產流水線生

28、產布局和生產流水線 Plant Layout&Product Flow 檢討檢討 Review 流程的設計依賴于工廠的布局.制造工藝類型和對生產流程的影響.The design of a routing depends on the layout of the plant,the type of manufacturing process,and the resulting production flow.生產布局生產布局 Manufacturing Layout生產布局是一個關于在生產場地如何放置生產資源的圖表.它通常包括生產場地的大小,機器的尺寸,工作中心或生產資源和它們放置于地面的位置.

29、The manufacturing layout is a plan of how the mfg.resources are positioned in the mfg.area.This usually includes the dimensions of the mfg.floor,the relative size of the machines,work center or mfg.resources,and their location on the floor.一個以生產功能的生產布局將機器或資源聚合在一起.生產流水線由如何利用生產資源來制造產品來決定.A functional

30、mfg.layout has like machines or resources grouped together on the mfg.floor.The product flow is determined by how the mfg.resources are used to produce the product.一個流水線產品的布局應合理地按順序布置機器或生產原料以便利于產品的生產.A flow mfg.layout has machines or mfg.resources arranged tin the sequence they are used to product t

31、he product.在一個以工作功能型的工廠布局中,資源根據不同的功能和部門而進行聚合.在某一機器上完成的固定數量的工作將傳遞到下一個部門.在這種布局中,不同部門間的物料和移動延長了總的生產時間.因為每個部門的物料不得不獨立地安排,所以等待時間是總的生產交期的重要部分.In a functionally oriented layout,resources are grouped according to their functions or depts.Jobs on the machines are usually completed in fixed quantities in each

32、 dept.and then moved to the next dept.In this layout,the movement of material between depts.Increases the total manufacturing time.Since each mfg.Resource has to be scheduled independently,queue time is a significant portion of the total mfg.lead time.12 在一個流水作業的環境中,資源排成流水線,產品按流水順序生產.這里制造活動以連續線或流水線的

33、方式進行.當一個零件完成后被移至下一工作中心,如此循環下去.In a flow environment,resources are placed at a flow line where the product is produced in a structured process.Here,manufacturing activities occur in a continuous line or flow.When one part is completed,it is moved to the next work center and so on.順序化的流水線布局 Structured

35、要了,因為機器和各種活動彼此相連以產生一個需要的產品.等候時間也能大大地減少或者消除,這是因為物料是在流水線上進行小數量加工.移動時間也因為產品是在工廠以直線型來移動而減少.在流水線布局下,運行時間占了生產交期中最高百分比.這樣就產生了一個產品的附加值.所以,一個工廠流水線生產的設計比一個功能的工廠設計更有效益.In a flow layout,reducing setup time becomes important because machines and activities are linked together to the required items.Queue time can

36、 also be substantially reduced or eliminated because materials are produced in a flow line and smaller lots.Move time is reduced since the product moves through the factory in a relatively straight line.In a flow layout,the run time accounts for the highest%of the total manufacturing lead time.This

37、produces a value added to the product versus a cost added when materials are held in queue.Therefore,a plant designed with flow production with flow production will be more efficient than a functionally oriented plant.(2)更少的生產周期時間 Less manufacturing cycle time(3)更少庫存和工序間的庫存 Less inventory in the sto

38、ckroom and work-in-process(4)更容易和更快地更改設計 Easier and quicker engineering changes(5)降低成本和更好地為顧客服務 Lower costs and better customer service overall流水線布局的目的是物料在最短的時間內及最低的成本.這是通過減少物料在生產工位等候所浪費的時間而達到目的.The goal in a flow layout is to get the material through the factory in the shortest time and at the lowe

39、st cost.This is done by reducing the time materials sit idle in queue on the manufacturing floor.14 時 間 移 動 範 圍 收 發 接 觸 降低成本的5T方針減少生產成本 記錄工廠布局和生產流水線 用示範項確認簡化的生產設計 生產設計提高目標 流程等同于 生產設計工藝技術的挑戰 The Process Engineerings Challenge對生產改善的影響對生產改善的影響 Impact of Manufacturing Improvements:在一個高效率的制造環境里,工藝技術部有兩個主

42、ctives15在一個功能型的環境里,基于產品系列或生產線組合,工藝技術部應重新評估可否對生產線重新設計.在一個流水線環境里,工藝技術部應尋找機會去提高倉存的速度以減少等待(排隊)時間.在以上兩個環境中,進行物流分析進而轉到產品成本的“5T”上將有利于以顧客為本的生產的提高.In a functional environment process engineering should begin evaluating mfg.Redesign based on product family or product line grouping.In a flow environment,proces
