Mukvich M. Constructing of a surfaces of technical forms in the system of the accompanying three-edge of a directing curve

Dissertation is devoted development of methods of geometrical design of ruled and tubular surfaces in the system of accompanying three-edge of Frenet of sending of curve after its set properties. Applying this method, a surface is formed, as a sum of two moving of formative line. From the condition of taking of tubular surfaces to the net from the lines of curvature the features of con-structing are investigational and analytical dependences are found for the different types of sending of curves: curve of hay-crop, cylinder curve, spherical curve, line of centers of circles of curvature of spiral line. Theoretical results are got used for planning of device for making of spirals of the screw from a rectilineal metallic strip. The results are introduced on "Zavod "Nizhinsilmash" and in the process of teaching at the VP NUBiP of Ukraine "NATI".
