Clamping and process routing. Process to determine such issues as size to ensure the parts machining Quality Learn how to use graphic materials, as well as manual control with designrelated books of various types of information the name of the source, to achieve the proficiency to use. Therefore, it is in our university life plays an important position. For me personally, I hope that through this course design is the work of their own future in an adaptive training, from training its own analysis of issues, problemsolving skills, to work for the future and lay a good foundation. Due to limited capacity to design there may be shortings, I earnestly urge the teachers to give criticism of correction 3 3 目錄 緒論 ................................................................................................................................ 1 一 工藝性分析 .............................................................................................................. 2 零件的作用 ....................................................................................................... 2 １ .2 審查零件的結(jié)構(gòu)工藝 ..................................................................................... 2 １ .3 確定零件的生產(chǎn)類(lèi)型 ..................................................................................... 2 二 確定毛坯、繪制毛坯簡(jiǎn)圖 ...................................................................................... 3 ２ .１選擇毛坯 ........................................................................................................ 3 ２ .２確定毛坯的尺寸公差和機(jī)械加工余量 ........................................................ 3 公差等級(jí) ............................................................................................... 3 鑄件的重量 ........................................................................................... 3 鑄件的形狀復(fù)雜系數(shù) ........................................................................... 3 鑄件的材質(zhì)系數(shù) ................................................................................... 3 鑄件分模線形狀 ................................................................................... 3 零件的表面粗糙度 ............................................................................... 4 擬定工藝路線 ................................................................................................... 4 三、工藝規(guī)程設(shè)計(jì) ........................................................................................................ 5 定位基準(zhǔn)的選擇： ........................................................................................... 5 制定加工工藝路線 ........................................................................................... 5 選擇加工設(shè)備及刀、夾、量具 ....................................................................... 7 四、切削用量及工時(shí)計(jì)算 ............................................................................................ 8 五 .夾具設(shè)計(jì) ................................................................................................................. 15 問(wèn)題的提出 .................................................................................................... 15 定位基準(zhǔn)的選擇 ............................................................................................ 15 切削 力及夾緊力計(jì)算 .................................................................................... 15 定位誤差的分析與設(shè)計(jì) ................................................................................. 17 夾具設(shè)計(jì)及操作說(shuō)明 ..................................................................................... 17 體會(huì)與展望 .................................................................................................................. 18 致 謝 ........................................................................................................................ 19 參考文獻(xiàn) ...................................................................................................................... 20 4 4 1 1 緒論 機(jī)械制造工藝學(xué)課程設(shè)計(jì)是在學(xué)完了機(jī)械設(shè)計(jì)制造工藝學(xué)、進(jìn)行了生產(chǎn)實(shí)習(xí)之后的下一個(gè)教學(xué)環(huán)節(jié)。它一方面要求學(xué)生通過(guò)設(shè)計(jì)能獲得綜合運(yùn)用過(guò)去所學(xué)過(guò)的全部課程進(jìn)行工藝及結(jié)構(gòu)設(shè)計(jì)的基 本能力，另外，也為以后作好畢業(yè)設(shè)計(jì)進(jìn)行一次綜合訓(xùn)練和準(zhǔn)備。學(xué)生通過(guò)
