Abstract: A method for additive manufacturing, wherein an additive-manufacturing head (12) is provided, configured both for directing one or more jets of powders, in particular metal powders, onto a region of a working surface (110), and for directing simultaneously a laser beam onto such a region, to form a laser-beam focusing spot (LS) on the region, and wherein, during direction of the powder jets and of the laser beam, the additive-manufacturing head (12) is simultaneously translated in a direction transverse to the direction of the laser beam so as to give rise to a trace (MRP) obtained by melting of the powders as a result of the power transmitted to the powders by the focusing spot (LS).

Abstract: Punching machine for the execution of holes on metal plates comprising a laser cutting head slidably supported by a pair of slides movable along a pair of Cartesian axes in a relatively restricted space with high velocities and accelerations. Movable balancing masses are operatively associated to the first and to the second slide.

Abstract: A laser machine tool for carrying out cutting or welding operations includes a laser head carried by a moving member which is displaceable with respect to a workpiece along two horizontal cartesian axes in a relatively wide space with movements involving relatively low accelerations. The laser head is displaceable on the moving member, along a pair of horizontal cartesian axes in a relatively restricted space with high speeds and accelerations, via a pair of slides to which respective balancing weights are operatively associated.

Abstract: The invention relates to a method for managing systems provided with redundant actuators of the type comprising at least a first system operating according to a first set of variables, representative of a physical quantity to be controlled and a second system operating according to a second set of said variables, representative of a physical quantity to be controlled, said first set of variables and second set of variables identifying one or more redundant variables. The method comprises the operations of commanding the actuators of the system through a numeric control unit and a servo control module to follow trajectories of the variables as a function of a set sequence.
