This paper develops the basic framework for Computer-Aided Design and Machining of composite ruled surfaces. Such surfaces are constructed by blending several patches which are segments of ruled surfaces. Taking advantage of the fact that a ruled surface is a one-parameter family of straight lines, methods are developed for blending of ruled patches. A new subdivision algorithm is also presented for generating sequences of cutter movements for machining of ruled patches.
