【正文】 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。11摘要工藝過程是指在生產(chǎn)過程中，通過改變生產(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程。10四、課程設(shè)計(jì)計(jì)總結(jié)2 零件的工藝分析2零件的結(jié)構(gòu)9 精度的分析加工過程直接決定零件和機(jī)械產(chǎn)品的質(zhì)量，對(duì)產(chǎn)品的成本和生產(chǎn)率都有較大影響，是整個(gè)工藝過程的重要組成部分。而機(jī)床行業(yè)又是裝備制造業(yè)的基礎(chǔ)行業(yè)，是向傳統(tǒng)機(jī)械工業(yè)、國防工業(yè)、汽車工業(yè)、航空航天工業(yè)、電子信息技術(shù)工業(yè)以及其他加工工業(yè)提供加工裝備的部門，是“支柱的支柱”。因此，正確的確定機(jī)械加工余量，對(duì)于節(jié)約金屬材料，降低刀具損耗，減少工時(shí)，從而降低產(chǎn)品制造成本，保證加工質(zhì)量具有十分重要的意義。采用第一種方法夾工件時(shí)，一般要先按圖樣要求在工件表面劃線，劃出加工表面的尺寸和位置，裝夾時(shí)用劃針或百分表找正后再夾緊。二、 機(jī)床夾具的分類機(jī)床夾具的種類繁多，可以從不同的角度對(duì)機(jī)床夾具進(jìn)行分類。（4）組合夾具 采用標(biāo)準(zhǔn)的組合夾具元件、部件，專為某一工件的某道工序組裝的夾具，稱為組合夾具。1. 定位裝置定位裝置的作用是使工件在夾具中占據(jù)正確的位置。機(jī)械的加工工藝及夾具設(shè)計(jì)是在完成了大學(xué)的全部課程之后，進(jìn)行的一次理論聯(lián)系實(shí)際的綜合運(yùn)用，培養(yǎng)學(xué)生綜合運(yùn)用所學(xué)基礎(chǔ)理論、專業(yè)知識(shí)與技能，獨(dú)立分析和解決問題的能力，有助于學(xué)生對(duì)專業(yè)知識(shí)、技能的進(jìn)一步提高，為以后從事專業(yè)技術(shù)的工作打下基礎(chǔ)。要保證以上尺寸要求，最好先將的內(nèi)孔和端面加工完成，再以內(nèi)孔和端面為定位基準(zhǔn)對(duì)頂表面進(jìn)行加工，最后以內(nèi)孔，端面，和頂面上?9的小孔（一面兩銷）為定位基準(zhǔn)，加工座體兩側(cè)板，其余表面粗糙度為50μm.二、工藝規(guī)程的設(shè)計(jì)確
