摘　　要：提出了多轴联动控制的新思路,通过对五轴数控系统模型的分析,建立坐标系,根据坐标变换理论,推导出五轴数控系统的顺运动学数学模型。通过求解雅可比矩阵及广义雅可比逆矩阵,得到五轴数控系统各轴的运动量,实现联动控制。计算机仿真结果表明,此方法能够实现五轴数控系统的高精度联动控制。A new method for multi-axis simultaneous control is proposed. Through the analysis of five-axis NC system model,coordinate is build for the system. According to the theory of homogeneous transformation,forward kinematics can be determined. The driving velocity for each axis on five-axis NC system is obtained by solving Jacobian and generalized inverse Jacobian. Computer simulation shows that high precision simultaneous machining can be obtained by using this method.
