Electric discharge machining apparatus and programming device

Abstract

An electric discharge apparatus includes electrode specification input means for inputting each electrode specification of a plurality of integral electrode where electrodes corresponding to a plurality of machining forms are arranged continuously on the same axis, machining detail input means for inputting data of a workpiece when electric discharge machining is performed using the integral electrode, and a machining program generation means for generating a machining program consisting of machining start position and a machining depth when electric discharge machining is performed using each electrodes based on the electrode specification and the thickness data of the workpiece thus input. There are further provided electrode specification input means and the machining detailed input means capable of inputting thereinto the following information: which part of the integral electrodes acts for rough machining and which part acts for finish machining, whether a finishing electrode is provided at one position or two positions, in what position relation they are, and how much the thickness of the workpiece is. Therefore, manual calculation by a worker is not required and a program can be made automatically only by inputting these parameters.
