Abstract
A wire electric discharge machining apparatus includes a machining unit that forms a product part by cutting off an outer frame portion from a workpiece and a control device that controls the machining unit. The machining unit machines a first boundary region in a boundary between the outer frame portion and the product part to leave an uncut portion, cuts off the product part from the outer frame portion by machining a second boundary region, which is the uncut portion, and repeats machining for the first/second boundary regions. When n is a natural number equal to or larger than 2, the control device sets, based on a machining state when the first boundary region is machined, different machining conditions as first machining conditions in machining the first boundary region for n-th time and second machining conditions in machining the second boundary region for n-th time.
