ABSTRACT:
A machining time estimating device for schedule control in an electric discharge machining operation, which is capable of estimating a machining period of time with high accuracy. With such an estimating device, an ideal machining period of time which has been determined according to machining conditions, is modified (since the actual machining procedure does not conform to the ideal conditions) in view of a variety of machining states and the machining conditions to achieve correction estimation. The machining states data includes data representing an area of a workpiece to be machined, a volume of the workpiece to be machined, a machining solution supplying method, and a configuration of the electrode to be used to machine the workpiece.
