摘　　要：在分析了各种刀具偏置虚空间和实空间概念及求解算法的基础上，提出了一种由高密度激光扫描点直接生成ＮＣ加工刀具路径的算法．该算法先求出激光扫描点集中每一点对应的偏置虚空间，再算出每一点对应的虚空间中Ｚ值最大的点即实偏置点，最后将所有实偏置点按一定方式输出，即可生成数控加工刀位轨迹．该算法适合于任何类型的刀具．In industry, it is often required to copy a part according to laser scan measurement data, when no original drawing or documentation is available. An algorithm for tool path generation directly from laser scan measurement data is presented. The algorithm includes three parts: calculate the virtual offset points in the projection zone of a certain tool position; get the corresponding real offset point with maximum Z value of all the virtual offset points; the tool path is generated according to all the real offset points corresponding to all the measurement data.
