【正文】 工藝過(guò)程是指在生產(chǎn)過(guò)程中，通過(guò)改變生產(chǎn)對(duì)象的形狀、相互位置和性質(zhì)等，使其成為成品或半成品的過(guò)程。裝配就是把加工好的零件按一定的順序和技術(shù)要求連接到一起，成為一部完整的機(jī)器（或產(chǎn)品），它必須可靠地實(shí)現(xiàn)機(jī)器（或產(chǎn)品）設(shè)計(jì)的功能。關(guān)鍵詞：工藝過(guò)程；機(jī)械加工工藝；裝配工藝AbstractProcess is in the production process, the production target by changing the shape, location and nature of each other, making it a finished or semifinished products of the process. Machinery manufacturing process generally includes parts of the machining process and machinery assembly process. Machining process (the process) is a mechanical method of processing the direct Blanks change the shape, size, location and nature of relative to bee qualified parts of the process. Processing machinery and spare parts directly determine the quality of the product, the product cost and productivity have a greater impact, the whole process is an important part. The assembly is processed by certain parts of the sequence and connect to the technical requirements to bee a plete machine (or product), it must be reliable machinery to achieve (or product) design features. Machinery assembly, generally include: assembly, adjustment, testing, testing, and so on. Not only is it necessary to manufacture machines the final stage, but also on the design of machinery, spare parts of processing machinery assembly quality and the quality of the test. By processing the design process, we can more effective use of existing resources equipment, reduce production costs and shorten the processing time to achieve the optimum production.Key words: Process。振興裝備制造業(yè)，必須首先發(fā)展機(jī)床制造業(yè)。車床除了用于車外圓外還能用于鏜孔，車端面、鉆孔和鉸孔，車床的多功能性可以使工件在一次定位安裝中完成多種加工，提高了生產(chǎn)效率。在這次設(shè)計(jì)過(guò)程中，廣泛的收集各種資料及標(biāo)準(zhǔn)，課程設(shè)計(jì)中另一個(gè)重要的設(shè)計(jì)為專用夾具的設(shè)計(jì)。一、 機(jī)床夾具在機(jī)械加工中的作用對(duì)工件進(jìn)行加工時(shí)，為了保證加工要求，首先要使工件相對(duì)于刀具及機(jī)床有正確的位置，并使這個(gè)位置在加工過(guò)程中不因外力的影響而變動(dòng)。這種方法無(wú)需專用裝備，但效率低，一般用于小批生產(chǎn)。（3） 能擴(kuò)大機(jī)床的使用范圍 （4）能降低成本 在批量生產(chǎn)中使用夾具后，由于勞動(dòng)生產(chǎn)率的提高、使用技術(shù)等級(jí)較低的工人以及廢品率下降等原因，明顯地降低了生產(chǎn)成本。常用的分類方法有以下幾種。專用夾具一般在批量生產(chǎn)中使用。（5）拼裝夾具 用專門的標(biāo)準(zhǔn)化、系列化的拼裝夾具而成的夾具，稱為拼裝夾具。2. 按使用機(jī)床分類夾具按使用機(jī)床可分為車床夾具、銑床夾具、鉆床夾具、鏜床夾具、齒輪機(jī)床夾具、數(shù)控機(jī)床夾具、自動(dòng)機(jī)床夾具、自動(dòng)線隨行夾具以及其它機(jī)床夾具等。2. 夾緊裝置夾緊裝置的作用是將工件壓緊夾牢，保證工件在加工過(guò)程中受到外力作用是不離開(kāi)已經(jīng)占據(jù)的正確位置。6. 其它裝置或元件它們是指夾具中因
