摘要
在NC仿真中,毛坯的三维图形处理是一项关键技术。一方面要实现几何造型的显示功能,另一方面还要求三维图形具有可加工性,加工成品的信息具有可记录性。设计了一种能够记录毛坯(工件)形状变化信息的数据结构,有效地实现了NC仿真中毛坯形状动态数据管理。
The key technical problem of roughcast in NC machining simulation is to handle threedimension shape ,which includes the method of display and machinability of three-dimension geometrical shape of roughcast, recording the information of parts process. A kind of data structure of three-dimension shape is used to record the roughcast （workpiece） shape changing information which manages workpiece entity dynamic data efficiently.
