    摘要： A method for monitoring the quality of laser-machining processes (500), including the operations of:
    acquiring via sensor means (540), in particular optical sensors, a machining-process signal (Xp) and calculating from said signal representing the process (Xp) parameters (E1,E2,DC) that represent the machining quality during the laser-machining process; and
    making available (130) corresponding reference parameters (E1r,E2r,DCr) representing a given machining quality, which are calculated from a process reference signal (Xr) acquired via said sensor means (540).
    executing in real time an operation of recognition (300) that a set of process observations (x;N1,N2,NDC,DIR) belongs to one or more of a plurality of statistical models (θ k ) that identify states of the machining process (500).

    摘要： A laser machine tool includes a base structure (2) carrying a first horizontal guide (6) on which a carriage (8) is slidable, the carriage (8) carrying a beam (10) which has a second horizontal guide (12) perpendicular to the first (6). A laser focusing head (16) is movable along the second guide (12) and can be made to travel along a vertical axis (Z) by at least one drive member. At least one of the drive members which brings about the vertical travel of the head (16) is independent of the movement of the head (16) along the beam (10).
