摘要
针对旋转轴非正交三转动二平动的五轴机床,提出一种通用的机床运动学分析和求解的方法,并把该方法推广到任意结构的三转动二平动五轴机床的运动学分析中。分析旋转轴正交和非正交的五轴机床的结构,将绕空间任意轴旋转的非正交结构机床的运动学变换统一到旋转轴正交结构机床的运动学变换中。对自由曲面和整体式叶轮的刀位文件进行后置处理,并利用Vericut软件进行加工仿真验证,证明该运动学分析方法的正确性。
For non-orthogonal three-rotation two-translation and five-axis machine tools with non-orthogonal rotation axes,a general kinematics analysis and solution method for machine tools is proposed.The method is extended to the kinematics analysis of a three-rotation two-translation five-axis machine tool with any structure.The structure of the five-axis machine tool with orthogonal and non-orthogonal rotation axes is analyzed,and the kinematic transformation of the machine tool with non-orthogonal structure rotating around any axis in space is unified into the kinematic transformation of the machine tool with orthogonal structure of rotating axis.The tool position files of free-form surface and integral impeller are post-processed,and the Vericut software is used for machining simulation verification,which proves the correctness of the kinematic analysis method.
