板金工制造多面体工件时,常需预先求出成形多面体上的某些二面角的大小,以便制造卡样板.目前实际工作中一般利用图解法解这个问题,具体画法在资料[1]和[2]中已有详细介绍.本文试图在实践经验基础上提供一种求卡样板角度的简单算法,它与图解法相比,主要优点是可得到较精确的结果,而且思路简洁,公式很少,不象图解法那样需要
Plate metal manufacturing polyhedron workpiece, often need to find out the shape of the polyhedron on the surface of some dihedral size, in order to make the card template.At present the actual work of the general use of graphic method to solve this problem, the specific method in the literature [1] and [2] has been described in detail.In this paper, based on practical experience, this paper attempts to provide a simple algorithm for calculating the card sample point of view. Compared with the graphical method, the main advantage of this method is that it can obtain more accurate results and has simple ideas and few formulas , Not as graphic as the need
