Abstract:

On the basis of the principle of NC machining for the spiral bevel gear and according to the generating motion between the generating gear and the work gear , a mathematical model of the generating motion of the spiral bevel gear tooth surface is proposed to determine the parameters of NC machining. The contact conditions of the gear cutting are then discussed , and the trajectory planning method of the spiral bevel gear in NC machining is presented and implemented to control the gear cutting on the self-developed NC milling machine for the spiral bevel gear. Experimental results show that the proposed trajectory planning method is feasible and effective in the control of NC machining for the spiral bevel gear.

Key words: spiral bevel gear, NC machining, mathematical model, trajectory planning
