Title:
FORMING METHOD OF CURVED SURFACE
Document Type and Number:
Japanese Patent JPS6015711
Kind Code:
A
Abstract:
PURPOSE:To obtain a curved surface even with a three-dimensional reference curve by producing the surface of a three-dimensional curved surface body from plural intermediate section curved surfaces. CONSTITUTION:At the outset, a three-dimensional curve 31a is specified and fed, and at the same time the data on sections 11 and 12 as well as section curves 11a and 12a are fed. Then a dividing point Si is obtained to divide the length of the curve 31a into m:n, and at the same time a tangent line TLN of the curve 31a is obtained at the point Si. An intermediate section 41 is formed so that it is vertical to the line TLN. This process to form the section 41 is repeated while changing the dividing ratio m:n successively from 0:1 through 1:0. As a result, many intermediate section curves 41a are obtained. These curves are connected to each other to obtain a smooth curved surface.
