摘要：研究了复杂形体计算机辅助修改方法;介绍了形体表面的单点修改和局部曲面修改方法;讨论了样条拟合修改空间模型的3种方法和样条的特性,在此基础上给出基于样条曲线拟合的模型修改方法与数学表达式。并研究了样条曲线技术在鞋楦形体设计中的应用,证明了该方法的可行性。
The computer-aided modification for complicated mold is investigated. The method of single-point modification and area modification on outer surface of complicated mold is introduced. Three models for modification based on spline fitting and features of the splines are discussed. The modification methods and mathematical expressions are given based on the above models. The spline fitting is applied to the design of shoe mold. The feasibility is also proven.
