摘　　要：以某一实际自由曲面为例,结合三坐标测量机(LKG90CS15 10 8)的特点,在实际反求工作中采用该三坐标测量机对自由曲面进行扫描测量,对测量数据进行预先处理,应用三角Bezier原理,编程实现曲面重构,得到曲面CAD模型.Some practical freeform surface is illustrated here, combining with the features of a CMM(LK G90CS15.10.8),in the practical process of reverse engineering. The surface is scanned by the CMM,and then the data is remodeled by applying the principle of triangular Bezier surface and programed to get the CAD model of the surface.
