摘　　要：针对逆向造型过程中复杂曲面拼接时边界处的连续性和光顺性问题,通过比较构建曲面常用几类曲线的优缺点,阐述了影响曲面光顺性的因素,并提出了相应的改进方法,同时利用逆向软件Imageware给出了检查及改进曲面光顺性的实例。In the reverse modeling process, a number of complex surfaces usually require a number of surface patches from the adjacent plank. When the border for the stitching easily leads to the continuity and smoothness of the problem, this paper, by comparing the commonly used types of building a surface curve of the advantages and disadvantages, describes the impact of surface fairing and presents the corresponding improvement of methods, and in the meantime, taking advantage o reverse software Imageware, gives examples of the inspection and improvement of surface smoothness.
