摘　　要：针对多轴数控砂带磨床的几何装配模型进行预处理,定义辅助坐标系与机床运动轴初始位置,分析机床工作台群组与刀具群组,将各运动轴的运动(平移、旋转)有序串联起来得到该磨床的运动学链。在机床运动学链的基础上推导坐标变换矩阵,获得磨床后置处理算法,构建后置处理坐标转换函数,基于MATLAB实现后置处理器的开发。最后,以宽弦空心风扇叶片为验证对象,通过VERICUT虚拟仿真环境和实机环境验证该后置处理算法的正确性。The geometric assembly model of multi-axis CNC abrasive belt grinder is preprocessed,the auxiliary coordinate system and the initial position of the machine tool motion axis are defined,the machine tool workbench group and tool group are analyzed,and the motion(translation and rotation)of each motion axis are sequentially connected to get the kinematic chain of the grinder.The coordinate transformation matrix is derived based on the kinematic chain of the machine tool,the post-processing algorithm of the grinder is obtained,the post-processing coordinate transformation function is constructed,and the development of the post-processor is realized based on MATLAB.Finally,taking the wide-chord hollow fan blade as the verification object,the correctness of the post-processing algorithm is verified by VERICUT virtual simulation environment and real machine environment.
