摘要
利用机器人运动学的齐次坐标变换原理和小角度假设,建立了三轴立式从加工中心刀尖到工件的封闭矢量链,推导出包含21项几何误差的三轴立式加工中心几何误差模型,给出基于运动轨迹误差测量的几何误差辨识方法。建立的基于运动轨迹误差测量的几何误差模型可以推广应用到其他型式的数控机床误差的建模、辨识和控制中。
A close chain of vector is built up,which is from tool point to workpiece on three axis Vertical Machine Center.Geometric error model of three axis VMC is worked out,which contains twenty-one variety of geometric errors,with the help of homogeneous coordinate transformation principle in kinematics of robot and micro-angle assumption on the basis of measuring Planar error.A method of distinguishing geometric error is put forward.
