個(gè)旋轉(zhuǎn)軸，提高了復(fù)雜曲面工件加工的靈活性，但加工時(shí)刀軸矢量發(fā)生改變，2 個(gè)旋轉(zhuǎn)軸需要聯(lián)動(dòng)運(yùn)動(dòng)，同時(shí)平動(dòng)軸要進(jìn)行補(bǔ)償運(yùn)動(dòng)，影響加工中心的加工精度和效率。五軸加工中心旋轉(zhuǎn)軸構(gòu)型指 2 個(gè)旋轉(zhuǎn)軸的配置組合方式，常用的旋轉(zhuǎn)軸構(gòu)型有 CA 型、 CB 型、 AB 型、 BA 型等 4 種。五軸加工中心運(yùn)動(dòng)鏈中的旋轉(zhuǎn)軸構(gòu)型差異，導(dǎo)致零件加工時(shí)在運(yùn)動(dòng)誤差和效率等運(yùn)動(dòng)性能方面存在差異。</p><h3

中以雙擺頭構(gòu)型為例從運(yùn)動(dòng)學(xué)角度進(jìn)行分析，采用 AB 旋轉(zhuǎn)軸構(gòu)型與 CA 旋轉(zhuǎn)軸構(gòu)型同時(shí)加工同一個(gè)工件，若工件裝夾姿態(tài)不變，則其加工運(yùn)動(dòng)學(xué)數(shù)據(jù)必然會(huì)存在差異。但是，當(dāng)在 CA 旋轉(zhuǎn)軸構(gòu)型情景下，將工件裝夾姿態(tài)繞工件坐標(biāo)系的 Y 坐標(biāo)軸整體旋轉(zhuǎn) 90° 后，再與 AB 旋轉(zhuǎn)軸構(gòu)型的初始加工情景進(jìn)行比較，二者在旋轉(zhuǎn)軸構(gòu)型的聯(lián)動(dòng)與工件裝夾姿態(tài)的關(guān)系上是等效的。所謂等效，是指二者的主副旋轉(zhuǎn)軸產(chǎn)生了對(duì)應(yīng)等效關(guān)系，AB 旋轉(zhuǎn)軸構(gòu)型的 A 、 B 分別與 CA 旋轉(zhuǎn)軸構(gòu)型的 C 、 A 相互對(duì)應(yīng)等效。二者整體的軸坐標(biāo)位置可能存在差異，但旋轉(zhuǎn)軸構(gòu)型的相對(duì)運(yùn)動(dòng)學(xué)數(shù)據(jù) (如軸的角速度、角加速度、累計(jì)行程、運(yùn)動(dòng)范圍等) 在運(yùn)動(dòng)學(xué)層面是等效的。</p><p>針對(duì)上述等效轉(zhuǎn)換關(guān)系建立模型，可以將原本關(guān)聯(lián)耦合卻姿態(tài)空間離散的旋轉(zhuǎn)軸構(gòu)型對(duì)比分析進(jìn)行同一化處理，實(shí)現(xiàn)旋轉(zhuǎn)軸構(gòu)型的連續(xù)性分析。通過(guò)該連續(xù)性分析，可實(shí)現(xiàn)旋轉(zhuǎn)軸方案與裝夾姿態(tài)的融合，利用中間態(tài)設(shè)計(jì)旋轉(zhuǎn)軸構(gòu)型的同時(shí)計(jì)算得到最優(yōu)裝夾姿態(tài)，并可進(jìn)一步拓展應(yīng)用于非正交型五軸加工中心設(shè)計(jì)。</p><p></p><p><br/></p></div>
