Abstract
A change in machining volume is calculated using a shape of the electrode and a shape of the workpiece expressed by three-dimensional models and machining condition data and the machining time is calculated according to actual machining status based on the calculated change in machining volume.
Claims12
An electric discharge machining apparatus comprising:
- an input unit that receives input of data about three-dimensional shape of an electrode, three-dimensional shape of a workpiece, and machining conditions;
- a machining volume calculation unit that calculates, based on the data about the shape of the electrode, the shape of the workpiece, and machining conditions, a machining volume that changes as machining of the workpiece by the electrode progresses;
