Simulation of Double Circular Arc Profile Spiral Bevel Gear Form Grinding Machining based on VERICUT

Abstract

The feasibility of machining double circular arc profile spiral bevel gear by numerical control forming grinding method is verified by VERICUT machining simulation.The tool path of the bevel gear and the tooth surface equation of the circular arc profile spiral bevel gear are studied，the axial cutting shape of the forming grinding wheel is obtained by the contact condition formula of the grinding surface and the tooth surface of the grinding wheel.Then，the selection criteria of the number of axes of the CNC forming gear grinding machine are proposed，and the models of the machine tool，forming grinding wheel and blank are established in VERICUT.Finally，the machining simulation of the double circular arc profile spiral bevel gear proves that the CNC forming grinding method can be used to process such gears，technical support for the application of CNC forming grinding on bevel gears.
