gives a comperatively detailed analysis to plane cross section method and projection method and introduces a new method of direct-interpolate maching.
对其中的平截面法和投影法作了较为细致的分析。
This article involves in plane cutting method to generate the measuring path and calculate the measuring point.
本文研究了截平面法生成理论测量路径和计算测量点 ,给出了简单稳定的方法计算测量点 ,计算定位点的算法采用了等距
A theoretical principle is found through the projection analysis of the parameters in relevant positions of a cutting plane,a quadratic surface and its projection planes,and the demon-stration of the conditions for projected line circle of a cutting plane and a quadratic surface,to re-solve precisely the section line and piercing point and intersection quadric of a quadratic surface.
对控制投影面、二次曲面及截平面三者之间相对位置的参数进行投影分析和对平面与二次曲面的交线投影成圆周条件的证明,为方便准确地求解二次曲面的截交线、贯穿点、相贯线等提供了理论根据,为其程序编制及计算机绘图提供了新的行之有效的方法。
