摘　　要：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。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 was developed by using their mapping relationship and its modeling principle and implementation means were also described. A precise 3D modeling for direct generation of a curved tie grain of a tie die from a 2D drawing supplied by customer can be obtained and finally a programming for NC processing will be generated automatically by above method.
