Numerical Control Machining Motion Solution of Split Straight Bevel Gear
In order to achieve the numerical control machining of a split straight bevel gear,based on the cutter location solution of split teeth of straight bevel gear and combined with the universal five-axis numerical control machine tool,the coordinate transformation relationship of flank milling of split straight bevel gear with cylindrical cutter was established,and the transformation matrices between each coordinate system were deduced.According to the known cutter axis vector and cutter center coordinates,the explicit function ex-pressions of the linear motion trajectory and rotary motion trajectory of the machine tool were solved respectively when the split straight bevel gear was flank milled by cylindrical cutter.The correctness of the motion trajectory was preliminarily verified by the simulation of gear cutting with VERICUT software.Through the tooth surface machining and tooth surface detection,the correctness of the numerical control machining motion solution of split straight bevel gear by cylindrical milling was further verified.
