The machining parameters of CNC high-speed dry hobbing of gears is significantly different from the traditional hobbing. In order to obtain the optimal machining parameters of CNC high-speed dry hobbing of planetary gear,the machining parameters optimization method is proposed. The CNC hobbing energy consumption and time consuming are considered as optimization objective,and the rotation speed of hob,X-axis feed speed and Z-axis feeding of hobbing machine are selected as optimization variables. The influences of optimization variables such as hobbing speed on energy consumption and time consuming of CNC dry hobbing are analyzed,and the multi-objective optimization model that takes into account the energy consumption and time consuming of CNC dry hobbing is established,the constraint conditions of the optimization model is also constructed. The genetic algorithm is applied to solve the multiple nonlinear optimization model,so as to obtain the optimal combination of CNC hobbing parameters. The effectiveness of the optimization model and model solving algorithm are verified by the optimization example and CNC hobbing experiment.
