    • The present invention provides a wire electric discharge machining apparatus for machining a workpiece (1) by electric discharge in which driving means (9) relatively moves a wire electrode (5) and the workpiece (1) while machining power supplying means (10) supplies a working energy between the wire electrode (5) and the workpiece (1). The wire electric discharge machining apparatus comprises working energy adjusting means (13) for decreasing the working energy per unit movement distance of the wire electrode (5) when the distance between an approach point (O) connecting a runway portion (4) and a machining configuration portion (2) on the relative movement passage of the wire electrode (5) and the workpiece (1) and a center of the wire electrode (5) in the machining configuration portion (2) is within a range where the machining volume of the workpiece (1) per unit movement distance of the wire electrode (5) is decreased. Therefore, it is possible to suppress an intrusion (6) from being formed on a machined face of the workpiece (1) near the approach point (O).
    • 本发明提供一种用于通过放电来对工件(1)进行加工的电线放电加工装置,其中驱动装置(9)相对移动线电极(5)和工件(1),同时加工电源装置(10) 线电极(5)和工件(1)之间的工作能量。 线材放电加工设备包括工作能量调节装置(13),用于当连接跑道部分(4)的接近点(O)和加工的距离(O)之间的距离减小线电极(5)的每单位移动距离的工作能量 在线电极(5)和工件(1)的相对移动通道上的配置部分(2)和加工配置部分(2)中的线电极(5)的中心处于加工体积 线电极(5)的每单位移动距离的工件(1)减少。 因此,可以抑制在接近点(O)附近在工件(1)的加工面上形成侵入(6)。
