Wire electrical discharge machine, machining program editor, wire electrode moving method and machining program editing method

A machining program editor that edits a machining program embedded in a non-transitory computer readable medium in which a movement route of a wire electrode of a wire electrical discharge machine is set, the movement route including a machining path used when performing electrical discharge machining on a workpiece while moving the wire electrode relative to the workpiece, the machining program editor comprising:

• a processor,
• wherein the processor
• determines whether or not a first route and a second route are set in the machining program embedded in the non-transitory computer readable medium in this order as the movement route of the wire electrode, the first route and the second route each including an approach path configured to cause the wire electrode to approach a start point of the machining path from a predetermined machining start point, the machining path, and an escape path configured to retract the wire electrode from an end point of the machining path to the machining start point, the approach path, the machining path, and the escape path being arranged in this order, and
• when the processor has determined that the first route and the second route are set in the machining program embedded in the non-transitory computer readable medium in this order as the movement route of the wire electrode, edits the machining program embedded in the non-transitory computer readable medium so as to cause the wire electrode to transition from the machining path of the first route to the machining path of the second route without moving the wire electrode along the escape path of the first route and the approach path of the second route.

A machining program editing method for causing a processor to edit a machining program embedded in the non-transitory computer readable medium in which a movement route of a wire electrode of a wire electrical discharge machine is set, the movement route including a machining path used when performing electrical discharge machining on a workpiece while moving the wire electrode relative to the workpiece, wherein the processor executes:

• a determination step of determining whether or not a first route and a second route are set in the machining program embedded in the non-transitory computer readable medium in this order as the movement route of the wire electrode, the first route and the second route each including an approach path configured to cause the wire electrode to approach a start point of the machining path from a predetermined machining start point, the machining path, and an escape path configured to retract the wire electrode from an end point of the machining path to the machining start point, the approach path, the machining path, and the escape path being arranged in this order;
• and
• a program editing step of, when it has been determined at the determination step that the first route and the second route are set in the machining program embedded in the non-transitory computer readable medium in this order as the movement route of the wire electrode, editing the machining program embedded in the non-transitory computer readable medium so as to cause the wire electrode to transition from the machining path of the first route to the machining path of the second route without moving the wire electrode along the escape path of the first route and the approach path of the second route.
