A method for producing cavities in a turbomachine disk, the cavities extending between first and second lateral surfaces of the disk, the method including positioning a ring facing the first surface, the ring including an inner periphery including protrusions complementary in shape to the cavities that are to be produced; circulating an electrolyte close to the protrusions on the ring; activating a first translational movement of the ring towards the second surface; activating a rotation of the disk; generating an electric current pulse in the electrolyte when the ring is substantially at the first surface, the pulse resulting in the ionic dissolution of the disk at the protrusions; reducing the speed of rotation to a first reduced speed, when the ring is substantially at the first surface, for a first period of time; and stopping the first translation of the ring when the ring is beyond the second surface. |
