ABSTRACT:
A wire cut type electric discharge machining method and apparatus, in which, when a fault occurs during a configuration machining operation, the configuration machining operation is suspended and skipped over to the next configuration machining operation, the method comprises: a step of storing machining start position data of the configuration machining operation with which the fault has occurred; a step of determining whether or not a machining operation is a finish machining operation; a step of collating, when the determination results in a finish machining operation, the machining start position data thus stored with machining start position data in the finish machining operation; and a step of carrying out the finish machining operation when the collation results in non-coincidence, and skipping the finish machining operation over to the following finish machining operation when the collation results in coincidence.
