Vovk V. The geometrical providing CAD of cutting part of spherical end milling cutters

The basic idea of work consists in development of theory of the geometrical providing of upgrading the automated planning of ballnosed end milling cutters, and creation on its basis CAD of this tool. Dependences have been got for determination of geometrical parameters in the static and kinematics systems of coordinates which take into account as structural features, so exploitation of such tool. On the basis of analysis of geometrical parameters the choice of the most optimum forms of front and back surfaces of spherical end milling cutters is grounded. Influence of structural parameters, cutting modes, corners of passing and inclination on kinematics geometrical parameters is set. With the purpose of receipt of more stable kinematics geometrical parameters along a cutting edge the possible corners of passing have been defined, depending on a diameter. On the base of theory of determination of geometrical parameters have been created CAD of cutting part of spherical end milling cutters with its software implementation. At development given CAD the tasks of shaping of surfaces of milling cutter are decided by conical grinding wheels for the construction of their solid models which can be used as electronic standards at control of milling cutters. The milling cutter of new construction is developed on which a patent is got on.
