Claims

[Scope of utility model registration request]

In the numerical control device of an electrical discharge machine that processes a workpiece by creating an electrical discharge between the workpiece and the electrode, the NC program registered in the memory of the numerical control device or the NC registered in a medium such as an NC tape or floppy disk is used. A program reading means reads the program block by block; a program analysis means analyzes the read NC program block by block; a program execution means executes the contents of the analyzed NC program blocks; a block end determination means for determining whether or not the program has been completed; an alarm detection means for detecting an alarm that occurs during the operation of the NC program; A numerical control device comprising an alarm determining means for determining whether an alarm is detected, a memory for storing the state of the numerical control device when an alarm is detected, and a storage means for storing the state of the control device in the memory.
