This paper describes the types of digital recording for profiles of parts and tools, their main program operations to be performed to solve problems within the theory of surface geometry generation: transformation of types, writing and reading files, movement on the plane, visualization, approximation by simple lines, representation on drawings, interpolation and editing procedures

Keywords: profile details, tool profile, shaping the surface, procedure, nodal points, Cartesian coordinates, polar coordinates, the profile angle, kink profile

This paper describes profile calculations of the shaper cutter for a splined bushing. The calculations are accompanied by modeling of the surface geometry to discover potential defects in generating the shape of a part and the subsequent editing of the shaper cutter’s profile

The paper describes distinct types of problems of generating surfaces by rolling. An algorithm has been developed to find a conjugate point, which became the basis for a procedure to determine the profile of a conjugate element, the procedure being the main one for a number of problems of surface generating by rolling for different types of elements.
