PROBLEM TO BE SOLVED: To provide a gear wheel processing simulation method which can execute a simulation by means of the three-dimensional model of a gear wheel having the same form as an actually processed gear wheel, and also provide a gear wheel processing simulation program and a gear wheel processing simulation device.;SOLUTION: The gear wheel processing simulation method has; a display procedure which makes a display device display a state in which a blank model and a cutter model are arranged on a gear cutting machine model which regulates a relative positional relation between the blank model and the cutter model; and a gear wheel model generation procedure which generates a gear wheel model from the blank model by means of a gear cutting simulation based on the blank model, cutter model and gear cutting machine model which are all displayed on the display device.;COPYRIGHT: (C)2006,JPO&NCIPI
