1、三坐標(biāo)測(cè)量（接觸型測(cè)量零件的設(shè)計(jì)班級(jí)：0781053學(xué)生：指導(dǎo)老師：摘要：隨著 CAD/CAM泉加工及快速成型等先進(jìn)制造技術(shù)的不斷發(fā)展，以及這些技術(shù)在機(jī)械行業(yè)中的普及應(yīng)用，機(jī)械設(shè)計(jì)與制造領(lǐng)域正發(fā)生著一場(chǎng)深刻的技術(shù)，傳統(tǒng)的二維設(shè)計(jì)及模擬量加工方式正逐步被基于產(chǎn)品三維數(shù)字化定義的數(shù)字化制造方式所取代。在這場(chǎng)技術(shù)中，逐步掌握三維 CAD/CAM的使用，并用于數(shù)字化的設(shè)計(jì)與制造是其中的關(guān)鍵。三坐標(biāo)測(cè)量機(jī)(CMM)則是一種高效率、高精度、多功能的檢測(cè)設(shè)備。七十年代以來(lái)在測(cè)量機(jī)上廣泛應(yīng)用電子計(jì)算機(jī)后，它的性能和自動(dòng)化程度都大為提高,使用范圍也更廣泛。昔日三坐標(biāo)測(cè)量機(jī)主要面向航空航天等高技術(shù)產(chǎn)業(yè)，而今日，它

2、在現(xiàn)代制造業(yè)的各個(gè)領(lǐng)域中都得到了廣泛的應(yīng)用，已成為機(jī)械制造業(yè)中發(fā)展最快的現(xiàn)代量?jī)x之一。本文就是采用 UG 三維建模設(shè)計(jì)出基于三坐標(biāo)測(cè)量技術(shù)能夠進(jìn)量的實(shí)體。然后把實(shí)體導(dǎo)入到 AutoCAD 繪圖，得到實(shí)體零件圖。所設(shè)計(jì)出來(lái)的實(shí)體的曲面圖形部分還要在微機(jī)上進(jìn)行 CAM 仿真加工并通過后處理得到 NC程序。然后利用三坐標(biāo)測(cè)量機(jī)對(duì)現(xiàn)有類似零件進(jìn)行檢測(cè)。這樣不僅能夠較好的掌握 UG 的三維建模方法，AutoCAD 的繪圖方式，還能熟悉三坐標(biāo)測(cè)量機(jī)的操作環(huán)境。：三坐標(biāo)測(cè)量技術(shù)實(shí)體設(shè)計(jì)UG指導(dǎo)老師簽名：The design of typical measurement component which bas
