摘要

A method of determining electric discharge machining conditions comprises the steps of establishing multiple sets of predefined machining parameters, establishing for each set of predefined machining parameters a set of basic machining data indicating relationships present during electric discharge machining among electric discharge machining current, machining depth and minimum electrode side surface undersize, selecting at least two sets of basic machining data from among the multiple sets thereof in accordance with a given set of predefined machining parameters, and inferring and generating machining condition data representing a series of pairs of machining depth values and corresponding electric discharge machining current values required for machining the workpiece to a prescribed configuration and dimensions, the electric discharge machining current values in the series progressively changing with increasing machining depth value from a value larger than the electric discharge machining current value of the selected set of basic machining data to a value smaller than the electric discharge machining current value of the selected set of basic machining data.
