基于汽车轮胎花纹的空间曲面造型研究

针对轮胎模具加工中平面花纹到空间造型的转换问题，运用映射关系，提出了一种高效、高精度、实用的造型方法，并分析了其基本原理及实现方法。实现了由客户提供的轮胎设计二维图样，直接生成轮胎模具基模胎面及花纹的精确三维造型，并自动生成数控加工程序。

Study on a Spatial Surface Modeling of Vehicle Tire Grain

Aiming at the conversion of a plane grain into a spatial surface modeling during a die processing of tie, an efficient, precise, and practical modeling method w as developed by using their mapping relationship and its modeling principle and implementation means were also described. A precise 3D modeling for direct gener ation of a curved tie grain of a tie die from a 2D drawing supplied by custo mer can be obtained and finally a programming for NC processing will be generate d automatically by above method.
