During types synthesis of kinematic scheme , there are two tasks need to be accomplished , one is transformation of each building block coordinate system in to machine ( global ) coordinate system , the other is linear transformation of each building block to align the axes 在運(yùn)動方案的型綜合中,需要進(jìn)行兩項(xiàng)工作:一是將各備選機(jī)構(gòu)坐標(biāo)轉(zhuǎn)換為機(jī)器的通用坐標(biāo);二是將各備選機(jī)構(gòu)的軸線首末端空間方位按組合的先后順序?qū)R。
According to the decoupling of type synthesis of mechanism and the relationship between control and error software compensation , the unsymmetrical 3 - dof translational weakly - coupled parallel mechanism for cmm was selected , the positive and negative solutions of mechanism position an error model were analyzed 根據(jù)機(jī)構(gòu)型的解耦性與控制和誤差軟件補(bǔ)償?shù)年P(guān)系,選擇非對稱型三平移弱耦合并聯(lián)機(jī)構(gòu)用于坐標(biāo)測量機(jī),分析了該機(jī)構(gòu)位置的正反解,建立了誤差模型。
Aiming at the deficiency of traditional nc machine tool and parallel machine tool , the advantages of traditiona nc machine tool and parallel machine tool are used for reference , three hybrid type pmt , which combine serial structure with parallel structure , are proposed in this dissertation tbiough type synthesis , invention patents have been applied for them 針對傳統(tǒng)數(shù)控機(jī)床和現(xiàn)有并聯(lián)機(jī)床不足之處,借鑒了傳統(tǒng)數(shù)控機(jī)床和現(xiàn)有并聯(lián)機(jī)床的優(yōu)點(diǎn),將串聯(lián)結(jié)構(gòu)與并聯(lián)結(jié)構(gòu)有機(jī)融合,通過機(jī)型綜合,提出了三種混聯(lián)結(jié)構(gòu)并聯(lián)機(jī)床的新機(jī)型,并申請了發(fā)明專利。
