摘要
依据单一支路的逆运动学计算方程和并联机床工作空间到输入空间的摄动映射矩阵 ,建立了刀具轴向尺寸变化和机床误差之间的显格式公式 ,得到了在刀具长度补偿时 ,动导轨输入位移增量的计算式。
According to the single branch of inverse comepensation equation and the perturbation mapping Matrix,it is found on the distinct format formula between alteration of the tool axial size and machine tool error,thus the moving slideway input displacement increment will be derived from the formula when the tool length comepensation is provided.
