摘要
二维空间孔道的传统校核方法是把三维问题化成二维问题,再简化或近似处理,这样的方法在高精度场合往往不能满足设计要求;还有的是对孔表面网格化、布尔运算等,算法复杂,难于实现。本文从计算几何理论上探讨了三维空间孔的精确校核方法,简单、易行、可靠。
The tradirional verification of 3 - dimension holes is simplified to 2 - dimension. This method often makes mistakes in the higher accuracy condition. Other methods such as surface net treatment, boolean calculation, are very complicated. In this paper, we introduce an accurate verification method for 3 - dimension holes from the theory of calculation geometry. It is simple, efficient and practical.
