ABSTRACT
TThe product design is the plan for the product and its components and subassemblies. To convert the product design into a physical entity, a manufacturing plan is needed. The activity of developing such a plan is called process planning. It is the link between product design and manufacturing. Process planning involves determining the sequence of processing and assembly steps that must be accomplished to make the product. In the present chapter, we examine processing planning and several related topics.
Process Planning
PProcess planning involves determining the most appropriate manufacturing and assembly processes and the sequence in which they should be accomplished to produce a given part or product according to specifications set forth in the product design documentation. The scope and variety of processes that can be planned are generally limited by the available processing equipment and technological capabilities of the company of plant. Parts that cannot be made internally must be purchased from outside vendors. It should be mentioned that the choice of processes is also limited by the details of the product design. This is a point we will return to later.
摘要
產(chǎn)品設(shè)計(jì)是用于產(chǎn)品，及它的部件裝配的計(jì)劃。為了把產(chǎn)品設(shè)計(jì)轉(zhuǎn)換成一個(gè)實(shí)際物體，這需要一個(gè)制造計(jì)劃。而制訂一個(gè)這樣的計(jì)劃的行動(dòng)就叫做工藝規(guī)程制訂。它是產(chǎn)品設(shè)計(jì)和制造之間的連接，工藝規(guī)程制訂包括決定加工順序和制造產(chǎn)品所必須完成的裝配步驟。在以下文章中,我們將解釋工藝規(guī)程制訂和他的一些相關(guān)主題。
文章開(kāi)始，我們應(yīng)該區(qū)別在下列文章中被反復(fù)提到的工藝規(guī)程制訂和生產(chǎn)計(jì)劃。工藝規(guī)程制訂與如何制造產(chǎn)品和它的零件等工程技術(shù)問(wèn)題有關(guān)，制造零件和裝配產(chǎn)品需要什么樣的設(shè)備和工具？工藝規(guī)程制訂與產(chǎn)品制造物流管理有關(guān)系。它在工藝規(guī)程制訂后面與原料分類及獲得滿足制造充分?jǐn)?shù)量產(chǎn)品要求的資源有關(guān)。
工藝規(guī)程制訂
工藝規(guī)程制訂包括決定最適當(dāng)?shù)闹圃旒把b配步驟和順序，在這些順序和步驟中他們必須根據(jù)所提出的詳細(xì)的設(shè)計(jì)說(shuō)明書規(guī)范完成給定零件或產(chǎn)品制造。 能夠被計(jì)劃的工藝范圍和多樣性通常由于公司車間可用設(shè)備和技術(shù)能力而受到限制。在公司內(nèi)部不能夠制造的零件必須到外部市場(chǎng)購(gòu)買，工藝規(guī)程制訂所提及的工藝選擇同樣也受到詳細(xì)設(shè)計(jì)資料的限制，我們稍后將會(huì)回到這一點(diǎn)。
