The homogeneous transformations were made use of to analyze systematically the geometric errors of the two-axis system in an NC lathe.

利用齐次变换对数控车床两轴联动系统的几何误差进行了系统分析,根据小溜板坐标系的不同建立方法分两种情况分析了整个建模过程,论述了两轴间的正交误差对空间误差的影响,建立了两轴联动系统空间误差的数学模型,并利用该数学模型计算出某台数控车床两轴联动系统的空间误差。

The explicit, closedform dynamic model of flexible two-link robotic manipulators is developed based on homogeneous transformation matrices, finite element model and the Lagrangian formulation of dynamics.
