COMPUTER AIDED DEVELOPMENT OF CYLINDRICAL THREE WAY CONNECTION WITH OBLIQUE ANGLE INTERSECTION AXES

探讨利用计算机辅助计算．求出圆柱管三通接头展开图所需的几何要素尺寸的原理和方法．

Three-way connection has two cylindrical pipes. Each pipe surface must be devel oped in full-size pattern.This paper presents a new method making development of the connection.In this method, the element lenths of cylindrical pipe can be found with a computer.So that a computer program will be designed according to the mathematical r elationship on the datail drawing. An example is provided in this paper.All numeical solutions of the geometric elements of the development are provided by a computer. These valuse are x.y coodinates of retangular coodingnate system. So that.these values can be laid directly on the steel plate or used for digital-control gas-cutter.The fabication process,advantager and applied ranges also be analyzed and discussed.
