畢業(yè)設(shè)計(jì)是學(xué)生畢業(yè)前完成學(xué)習(xí)任務(wù)所必須的重要環(huán)節(jié)，它是我們機(jī)械制造及其自動(dòng)化專(zhuān)業(yè)四年所學(xué)專(zhuān)業(yè)課的綜合應(yīng)用，更是培養(yǎng)我們獨(dú)立思考和動(dòng)手能力的重要過(guò)程。 to determine the structure of the spindle box。設(shè)計(jì)的內(nèi)容包括：繪制多軸箱設(shè)計(jì)原始依據(jù)圖；確定主軸箱結(jié)構(gòu)；計(jì)算主軸、傳動(dòng)軸坐標(biāo)；繪制多軸箱總圖，、零件圖、加工示意圖。它能從多面、多工位、多軸對(duì)一個(gè)或幾個(gè)工件同時(shí)進(jìn)行加工，和一般的萬(wàn)能機(jī)床相比，具有設(shè)計(jì)周期短、成本低、自動(dòng)化程度高、加工質(zhì)量穩(wěn)定、減輕工人勞動(dòng)強(qiáng)度等優(yōu)點(diǎn)。
