NEW ASPECTS CONCERNING THE KINEMATIC GENERATION OF THE GENERATRIX AND DIRECTRIX CURVES OF THE GEOMETRICAL SURFACES
Ioan-Gheorghe SANDU, Eugen STRAJESCU
Abstract: The paper presents a theoretical study of the principle of the kinematics generation of the D and G curves of the geometric complex surfaces using the composition of the simple movements. In that sense, as a new original application, it is presented the cinematic generation of two largely used curves G and D of the real complex surfaces generated on machine-tools, respectively the generation of the hypocycloid at the generation of the surfaces of the flank of the cylindrical gears having a cycloid profile and the generation of the circular helix at the generation of the cylindrical helicoidally surfaces.
Key words: surface generation, generatrix, directrix, hypocycloid, cycloid, gears, helical surfaces.
