摘要
分析两个旋转轴非正交的倾斜旋转轴结构的五轴机床结构,运用机构学理论建立该类型五轴机床机构学模型。以刀具旋转型机床为例,使用齐次坐标变换矩阵和正向运动学分析建立倾斜旋转轴五轴机床的形状创成函数,最后通过逆向运动学求解出NC数据的分析公式,该公式简单且通用性强,为倾斜旋转轴结构的五轴机床的空间运动和坐标变换问题提出了通用的处理方法。
This paper analyzed the configuration of the five-axis machine tool with a nutating head whose rotational axis is in an inclined plane. The kinematics model is founded by using the mechanism theory on the analysis of the machine tool＇ s configuration. The machine tool＇ s form-shaping function matrix is derived based on the homogeneous coordinate transformation and the forward kinematics. The analytical equation of NC data is derived base on the inverse kinematics and the form-shaping function matrix. The derived equation is simple and high universality, which provide the spatial kinematics foundation and mathematic foundation for the fiveaxis machine tool with tilting rotational axis.
