基于图像空间的数控加工图形仿真

Simulation of NC Machining Based on Improved Image Space Method

在数控加工图形仿真验证中 ,传统的图像空间离散方法提供的观察分析手段较少 ,限制了它的应用 ;而物体空间方法计算量大 ,不具有实时性。介绍一种在基本图像空间离散法的基础上对数据结构和算法作了改进的方法 ,一方面不会失去仿真实时性 ,另一方面为用户提供了更多且方便有效的分析观察手段 。

In this paper,the authors introduce an image space discrete method for NC machining process simulation.Image space technique was introduced by Van Hook firstly,he realized NC simulation on personal computer. But,it could not give users accurate information about milling results and effective observing way in simulation.To improve Hook's algorithm,the authors organize the data structure in a new way.The improved algorithm makes it possible for users to cut or scale the image and evaluate every image point accurately. At the same time,the descent of time efficiency is trivial.The algorithm has been implemented perfectly on workstation,the correctness of this technique is proved practically.
