摘要： 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.

摘要： The invention relates to electrical discharge milling machines using tool electrodes subject to longitudinal wear. The inventive discharge milling machine is equipped with a numerical controller executing at least one control cycle for compensating the wear considering the following steps:
- determining the volume Q eroded by each discharge,
- calculating the distance s travelled by the tool from one effective discharge to the next,
- calculating the actual eroded linear volume M [m 3 /m] for at least one effective discharge, M forming a measurement sample from the values Q and s,
- comparing said sample M with the corresponding set value C to generate an error D = C - M [m 3 /m],
- calculating and transmitting a command by the numerical controller intended to reduce this error D during the following cycle or cycles.摘要翻译： 本发明涉及使用纵向磨损的工具电极的放电铣床。 本发明的放电铣床配备有数字控制器，其执行用于补偿磨损的至少一个控制周期，其考虑以下步骤： - 确定由每个排放物侵蚀的体积Q， - 计算由一个有效排放到该工具的行程 接下来， - 计算至少一个有效放电的实际侵蚀线性体积M [m 3 / m]，M从值Q和s形成测量样本， - 将所述样本M与相应的设定值C进行比较，以产生 误差D = C-M [m 3 / m]， - 计算并发送数字控制器的命令，旨在在随后的周期或周期期间减少该误差D.
