Control device for die-sinking electrical discharge machine

A control device of a die-sinking electrical discharge machine that performs electrical discharge machining by a die-sinking electrical discharge machine by successively executing a plurality of processing programs that have commands including electrode numbers, comprising:

• a program analyzing unit that extracts the electrode numbers included in the processing programs, determines duplication of the electrode numbers among the processing programs to display a result of determination, and that stores correspondence between a revision electrode number that is specified by a user and an in-use electrode number that is used in the processing program for each of the processing programs;
• and
• a program executing unit that executes each of the processing programs by reading the revision electrode number instead of the in-use electrode number used in each of the processing programs based on the stored correspondence at the time of execution of the processing programs.
