Abstract
An electroerosion machining device to machine a piece ( ) by milling successive layers includes a member ( ) to drive in rotation an electrode-tool ( ) of tubular shape and a digital control unit (CN) to control the three-dimensional movement (x, y, z) between the electrode-tool and the piece ( ). A regulation module (MR) is adapted to simulate the longitudinal wear of the electrode-tool and to compensate it along its path. According to the type of geometric configuration between the electrode-tool and the piece, namely the presence or absence of an opening below the electrode-tool and the presence or absence of one or two walls, different values of longitudinal wear are provided and transmitted to the digital control unit (CN). There is thus obtained a high precision and planarity of machining.
