ON THE GRAPHICAL METHODS OF THE CONICAL
TRANSITION SURFACES DESIGN
The component parts of various machines, equipments, devices or
installations from the machine-building consist of combinations of polyhedral or
curved surfaces. The passing from one surface to another is achieved by the
crooked lines in space, having non-coplanar points and which can be polygons
or curved lines. If the surfaces that compose the part are developable, they can
be made of flat sheets and their intersection line is even their joining line, e.g.
the welding belt. The paper presents the manufacturing possibility of some
parts of the flat sheets composed from the joining of two conical surfaces
having a common base.
