An electric discharge machine has a hand operation panel (10), which is provided with a manual pulse generator (12) with a rotating part (17). The manual pulse generator (12) generates a pulse signal corresponding to a rotation angle position of the rotating part (17). Further, the manual pulse generator (12) outputs a move command for changing (i.e., increasing or decreasing) a relative distance between a tool electrode and a workpiece and commands for changing set values of machining conditions, based on the pulse signal from the manual pulse generator (12). |
