    摘要： 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.

    摘要： A wire electrical discharge machine includes: a mounting table having a placement plane on which a workpiece can be placed; a first guide portion and a second guide portion for stretching a wire electrode therebetween. The first guide portion is integrally equipped with a probe. The relative position in the placement plane between the probe detecting its abutment with the workpiece and the first guide portion before moving the relative position between the first guide portion and the second guide portion is stored as an offset. This offset is corrected based on the tilt information indicating the tilt state of the workpiece relative to the placement plane. Thus, it is possible to obtain the corrected offset in accordance with the tilt state of the workpiece after changing the relative position between the first guide portion and the second guide portion.

    摘要： A wire electrical discharge machine includes an upper wire guide and a lower wire guide supporting a wire electrode, a probe provided on an upper guide block having the upper wire guide, an offset storage unit for storing an offset amount from the upper wire guide to the probe, a position shift drive unit for changing the relative position between the table, and the upper and lower wire guides, a drive controller for controlling the position shift drive unit, a contact position calculator for calculating a contact position that is a position of the probe when it comes in contact, and a machining start position calculator for calculating a machining start position of the wire electrode, based on at least two contact positions and the offset amount. The drive controller controls the position shift drive unit so that the position of the wire electrode becomes the machining start position.

    摘要： A wire electric discharge machine that machines a workpiece by supplying a working fluid to a work tank where the workpiece is placed includes a temperature monitor, which exercises control so that the temperature of the working fluid is within a predetermined range. An alarm is displayed when the temperature of the working fluid is outside an allowable temperature range. A time that has elapsed since the temperature of the working fluid falls within the allowable temperature range from outside the allowable temperature rage is measured and when the measured time exceeds a preset working fluid temperature difference disappearing time, the alarm is called off.
