扩大并联机床工作空间方法的研究

Study of Turntable Decomposition on Seven-axis Linkage Parallel Kinematics Machine

针对机床坐标系和工件坐标系的关系,采用一致坐标系转台转角分解和非一致坐标系转台转角分解方法,从而达到扩大并联机床工作空间的目的。

According to the relation of the machine coordinate system and the workpiece coordinate system,the turntable angle decomposition algorithmic of the consistent coordinate system and the turntable angle decomposition algorithmic of the non-consistent coordinate system were developed and workspace of PKM was enlarged.
