實(shí)體設(shè)計(jì)軟件設(shè)計(jì)的普通麻花鉆及群鉆的計(jì)算機(jī)輔助三維造型技術(shù)

1、摘要本文論述了用CAXA實(shí)體設(shè)計(jì)軟件設(shè)計(jì)的普通麻花鉆及群鉆的計(jì)算機(jī)輔助三維造型技術(shù)并建立了與之相關(guān)的群鉆數(shù)據(jù)庫(kù)。首先，將普通麻花鉆、群鉆這些結(jié)構(gòu)復(fù)雜、造型困難的機(jī)械加工工具用CAXA三維造型設(shè)計(jì)軟件設(shè)計(jì)出了比較理想的三維幾何造型，在CAXA實(shí)體設(shè)計(jì)軟件的應(yīng)用和群鉆的CAD造型上有較大的創(chuàng)新，從而有助于群鉆在生產(chǎn)實(shí)際中的使用和推廣。此外，用SQLServer2000建立了實(shí)用性較強(qiáng)的群鉆數(shù)據(jù)庫(kù)。設(shè)計(jì)過(guò)程中以C語(yǔ)言為開發(fā)語(yǔ)言以VisualC

2、6.0為開發(fā)平臺(tái)實(shí)現(xiàn)了人機(jī)交互接口界面并實(shí)現(xiàn)了系統(tǒng)自動(dòng)對(duì)群鉆的二維圖形、三維圖形以及群鉆切削部分的基本幾何參數(shù)的檢索、瀏覽與輸出。與此同時(shí)，本文還分析了群鉆的幾何形狀及其結(jié)構(gòu)參數(shù)較細(xì)致地闡述了普通麻花鉆在其幾何形狀上的缺陷和群鉆在生產(chǎn)實(shí)際中的優(yōu)點(diǎn)，詳細(xì)介紹了群鉆的幾何參數(shù)及其演變過(guò)程，并說(shuō)明了它的刃磨方法。因此，使鉆頭使用者對(duì)群鉆的幾何形狀特點(diǎn)有更深入的了解，熟悉群鉆的刃磨方法和造型過(guò)程，并能方便地查詢有關(guān)群鉆切削部分的基本幾何參數(shù)，從

3、而在生產(chǎn)實(shí)際中對(duì)群鉆的制造、使用和推廣普及方面有較大的促進(jìn)作用。關(guān)鍵詞：麻花鉆，群鉆，CAXA，數(shù)據(jù)庫(kù)SQLServer2000VisualC6.0AbstractAbstractThedesignprocessofthethreedimensionalshapeofthedrillthebasicQundrillbyCAXAentitydesignsoftwareisintroducedaswellasthefoundofthedat
