Abstract
A wire electrical discharge machine and a wire electrical discharge machining method are provided. The wire electrical discharge machine is equipped with a core position recognizing unit configured to recognize the position of a core which is fixed by a core fixing function, a core removal unit configured to remove the core, which is in the recognized position, from a workpiece on which machining has been performed, and a core removal determining unit configured to determine whether or not the core in the recognized position has actually been removed.
Claims13
A wire electrical discharge machine, in which a wire electrode and a workpiece are moved relative to each other according to a machining program, and electrical discharge machining is carried out on the workpiece by an electrical discharge generated between the wire electrode and the workpiece, the wire electrical discharge machine having a core fixing function for fixing a core, which is formed by the electrical discharge machining, to a base material of the workpiece by attachment and deposition of machining chips generated as a result of the electrical discharge machining, comprising:
- a core position recognizing unit configured to recognize a position of the core which is fixed by the core fixing function;
- a core removal unit configured to remove the core, which is in the position recognized by the core position recognizing unit, from the workpiece;
- and
- a core removal determining unit configured to determine whether or not the core, which is in the position recognized by the core position recognizing unit, has actually been removed by the core removal unit.
A wire electrical discharge machining method, in which a wire electrode and a workpiece are moved relative to each other according to a machining program, and electrical discharge machining is carried out on the workpiece by an electrical discharge generated between the wire electrode and the workpiece, the wire electrical discharge machining method being implemented by a wire electrical discharge machine having a core fixing function for fixing a core, which is formed by the electrical discharge machining, to the workpiece by attachment and deposition of machining chips generated as a result of the electrical discharge machining, the method comprising:
- a recognizing step of recognizing a position of the core which is fixed by the core fixing function;
- a removing step of removing the core, which is in the position recognized by the recognizing step, from the workpiece;
- and
- a determining step of determining whether or not the core, which is in the position recognized by the recognizing step, has actually been removed in the removing step.
