摘　　要：利用磨料水射流对材料进行小加工余量的边缘切割时,会出现射流偏转现象从而导致加工误差,如何快速获得切割截面形貌对实现精密切割有着非常重要的作用。本文研究了一种基于三维激光扫描的磨料水射流切割轮廓检测方法。该方法采用高精度激光扫描仪对切割截面轮廓进行数据采集,然后通过定义坐标系得到与实际零件位置相匹配的点云模型,最后提取出切割截面的轮廓曲线,并进行数据分析。When AWJ is used to cut the edge of material with small machining allowance,the deflection of AWJ will lead to machining error.How to obtain the cutting section morphology quickly plays an important role in precision cutting.In this paper,a profile measurement method based on 3D laser scanning is studied.In this method,a high-precision laser scanner is used to collect the data of the cutting profile,and the point cloud model matching the actual part position is obtained by defining the coordinate system.Finally,the profile curve of the cutting section is extracted and the data is analyzed.
