The invention relates to a method of electrochemically machining an electrically conductive workpiece in an electrolyte by applying electrical pulses between the workpiece and an electrically conductive electrode, one or more machining pulses (MP) alternating with voltage pulses (PP) for depositing passivation layers on the workpiece. The amplitude of the voltage pulses is adjusted during an adjustment procedure in which the amplitude of the voltage pulses is increased gradually from zero to the voltage at which the workpiece starts to dissolve in the electrolyte. After each voltage increase the resistance of the gap between the electrode and the workpiece is measured. The voltage value for the highest gap resistance is stored in a memory and used during further machining. The time span of the voltage pulses may be divided into time slices (Dt) and for each time slice the voltage is adjusted for maximum gap resistance during that time slice.

L'invention concerne un procédé permettant d'usiner par électrolyse une pièce conductrice dans un électrolyte, grâce à des impulsions électriques appliquées entre cette pièce et une électrode conductrice, une ou plusieurs impulsions d'usinage (MP), appliquées en alternance avec des impulsions de tension (PP) permettant de former un dépôt de couches de passivation sur ladite pièce. On règle l'amplitude de ces impulsions de tension pendant une procédure de réglage, au cours de laquelle l'amplitude de ces impulsions de tension diminue progressivement, passant ainsi de zéro au niveau de tension auquel la pièce commence à se dissoudre dans ledit électrolyte. Après chaque hausse de tension, on mesure la résistance de l'espace séparant l'électrode de la pièce, le niveau de tension correspondant à la résistance maximale de cet espace étant stockée dans une mémoire pour ensuite être utilisée au cours d'un usinage ultérieur. Le laps de temps des impulsions de tension peut en outre être divisé en plusieurs tranches de temps (Dt), la tension étant réglée pour chacune de ces tranches de temps afin de maximiser la résistance dudit espace.
