Abstract
An electric discharge machining apparatus having: a machining condition storage device ( ) including a machining condition database in which machining condition data are stored; an input-output device ( ) for reading either of shape data of a tool electrode ( ) and machining shape data of a subject (W) for machining; a shape computing device ( ) for extracting a plurality of sections from the shape data, mesh-dividing the sections into split elements, giving mesh data of solidness or hollowness and extracting machining shape characteristic from the mesh data; and a machining condition setting device ( ) for selecting a machining condition while making the machining shape characteristic correspond to machining condition data in the machining condition database of the machining condition storage device ( ). Even when the machining shape is complex, more efficient machining can be performed because an appropriate machining condition can be set.
