摘要
基于机器人运动学原理,结合齐次坐标变化理论和刀具与工件构成的联结矢量链概念,以一台加工中心为对象,建立了包含21项几何误差的数控机床误差模型,并提出了误差的分离方法,所提出的误差模型和分离方法可推广到多轴数控机床误差分析上。
Base on kinematics of robot, combining homogeneous coordinate transformation and tool-work piece coupling vector chain, taking a machining center as a example, 21 geometrical error model of NC machine tool has been found. Separation method of error has been put forward. The model and the method can be popularized to analyze on the error of multi-axis NC machine tools
