Summary:To position a wire electrode to a proper processing start position with respect to a processed object supported by a table.SOLUTION: A wire electric discharge processing machine 10 includes: an upper wire guide 16 and a lower wire guide 18 supporting a wire electrode 14; a probe 32 provided at an upper guide block 20 in which the upper wire guide 16 is installed; an off-set storage part 46 which stores an offset amount from the upper wire guide 16 to the probe 32; a position displacement drive part 24 which displaces a relative position between a table 12 and the upper and lower wire guides 16, 18; a drive control part 40 which controls the position displacement drive part 24; a contact position calculation part 44 which calculates contact positions, positions of the probe 32 when the probe 32 contacts with a processed object; and a processing start position calculation part 48 which calculates a processing start position of the wire electrode 14 based on the at least two contact positions and the off-set amount. The drive control part 40 controls the position displacement drive part 24 so that a position of the wire electrode 14 is set to the processing start position.SELECTED DRAWING: Figure 1 【課題】テーブルに支持された加工対象物に対してワイヤ電極を適切な加工開始位置に位置決めする。【解決手段】ワイヤ放電加工機１０は、ワイヤ電極１４を支持する上ワイヤガイド１６おおよび下ワイヤガイド１８と、上ワイヤガイド１６が設置される上ガイドブロック２０に設けられたプローブ３２と、上ワイヤガイド１６からプローブ３２までのオフセット量を記憶するオフセット記憶部４６と、テーブル１２と上下ワイヤガイド１６、１８との相対位置を変位させる位置変位駆動部２４と、位置変位駆動部２４を制御する駆動制御部４０と、接触したときのプローブ３２の位置である接触位置を算出する接触位置算出部４４と、少なくとも２つの接触位置とオフセット量とに基づいて、ワイヤ電極１４の加工開始位置を算出する加工開始位置算出部４８と、を備え、駆動制御部４０は、ワイヤ電極１４の位置が、加工開始位置となるように、位置変位駆動部２４を制御する。【選択図】図１
