Nc machining process of the content of the machine tool than normal processing process content plex. This is because the numerical control machine tool is expensive, if only simple processing of working procedure, in economic not worthwhile, so on the nc machine more plex process is arranged normally, even in general in machine tool of the difficult to plete the process. Numerical control machine tool than regular programming machine process planning of plex. This is because in the processing technology of the conventional machine tools in need not consider of problems, such as the arrangement of the steps in the process of work, the cutting point, change the tools point and go to determine the knife route, in the numerical control processing, it all without exception to all bee fixed program content, and because of this feature, for the processing procedures to the correctness and rationality of the highly demanding, there can be no mistake, or processing not qualified parts.Keywords: axial parts。數(shù)控機(jī)床加工程序的編制比普通機(jī)床工藝規(guī)程編制復(fù)雜。數(shù)控加工的工序內(nèi)容比普通機(jī)床的加工的工序內(nèi)容復(fù)雜。院年 月 日3 / 35畢業(yè)設(shè)計(jì)( 論文)進(jìn)度 計(jì)劃表日 期 工 作 內(nèi) 容 執(zhí) 行 情 況 指導(dǎo)教師簽 字 熟悉零件圖完成零件的工藝性分析,確定毛坯的類型、制造方法和機(jī)械加工工藝規(guī)程并編制出零件的加工工藝卡片 完成零件加工方案設(shè)計(jì) 完成零件圖的繪制 查找并整理資料 整理并完成設(shè)計(jì)說明書 的編寫 完成圖紙和說明書的輸 出打印教師對進(jìn)度計(jì)劃實(shí)施情況總評 簽名 年 月 日 本表作評定學(xué)生平時(shí)成績的依據(jù)之一。正文編寫內(nèi)容:(字?jǐn)?shù) 1 萬左右,含圖 25 頁以上) 。 院年 月 日2 / 35畢業(yè)設(shè)計(jì)(論文)任務(wù)書題目: 配合件的工藝與編程任務(wù)與要求:對工件的工藝分析及加工路線的制定,手工編制加工程序,加工工件并進(jìn)行廢品分析。 學(xué)院畢 業(yè) 設(shè) 計(jì)(論 文)論文題目:配合件的工藝與編程所屬系部: 航空制造工程系指導(dǎo)老師: 職 稱: 講師學(xué)生姓名: 班級、學(xué)號: 專 業(yè): 西安1 / 35西安繪制手工圖紙(A3),采用放大比例主要是為了方便答辯使用。時(shí)間: 2022 年 11 月 25 日 至 2022 年 12 月 15 日 共 3 周所屬系部: 學(xué)生姓名: 學(xué) 號:
