    • Spark-erosion machining method and machine implementing a machining gap, a process regulator, a numerical control system, a Nominal Trajectory. The latter describes the movement of the tool electrode relative to the part as it ought to proceed if no disturbance were to occur during the machining. Information contained in the Nominal Trajectory is used to define at least two control vectors Vg, Vp which orient, within the coordinate system XYZ, two independent regulation movements. The first, or Gap Vector Vg , defines the direction in which a first regulation movement of the axes of the machine must be performed to maintain the removal of material. The second, or Position Vector Vp , defines the direction in which a second regulation movement of the axes of the machining machine must be performed to correct a tool electrode position error. The respective amplitudes of the regulation movements are calculated in real time by the process regulator.
    • 火花腐蚀加工方法和机器实现的加工间隙中,工艺调节器,一个数控系统,标称轨迹。 后者描述工具电极相对于运动的部分,因为它应该推进时没有干扰,且在加工期间发生。 包含在额定轨迹的信息被用来定义至少两个控制矢量Vg的,VP哪个定向,所述坐标系XYZ,两个独立的调节运动内。 第一,或间隙矢量Vg定义了机器的轴的第一调节运动必须被执行以保持移除材料的方向。 第二,或位置矢量Vp限定其中加工机的轴线的第二调节运动必须被执行以校正刀具电极位置误差的方向。 调节运动的respectivement幅度实时由工艺调节计算。
