This paper presents aspects of a new manufacturing technology cylindrical Archimedean worms on NC lathes using standard frontal – cylindrical milling tools. The frontal-cylindrical milling tools is tilted from the perpendicular to the axis of symmetry of the worm by an angle roughly equal with the pressure angle of the worm flank. At the same time the symmetry axis of frontal-cylindrical milling tools is contained in a plane parallel to the axis of symmetry of the worm. The plane is positioned for the symmetry axis at a distance that we call eccentricity. Depending on the location of the milling tool, shall be determined the shape of the profile resulted in axial plane to be able to be compared to the nominal profile of an Archimedean worm. The profile shape is determined using coordinate transformations. The program that generates the necessary points is AutoLISP and representations are made in AutoCAD.
