Laser operating machine for additive manufacturing of objects by laser sintering, comprising a transport structure (), which is movable in a work space (), operating according to a first system of movement axes (X, Y, Z) and configured to support one or more nozzles () for lid emitting sintering powder jets to be sintered on a work substrate () and an optical laser assembly () for conveying a laser beam (L) in a laser spot (S) focused on said work substrate () to sinter said powders, According to the invention, said optical laser assembly () is integrally associated with said transport structure () and a movable element () is also integrally associated with said transport structure () operating according to a second system of movement axes (u, v), said movable element () comprising a tool-carrier frame (), on which one or more nozzles () for emitting sintering powder jets are arranged, associated with said second system of movement axes (u,v) and movable with respect to said optical laser assembly ().

Laser operating machine for additive manufacturing by laser sintering and corresponding method

A management method for a redundant axis laser machine of the type comprising a movable structure controlled by actuators and operated according to a first set of variables (X, Y, Z, A) and an operating head operated according to a second set of said variables (W, B, C), said first set of variables (X, Y, Z, A) and second set of variables (W, B, C) identifying one or more redundant variables. Such method envisions a filtering allowing the work trajectory to be decomposed into defined trajectories for a first low dynamic system made up of said first set of variables (X, Y, Z, A) and a second high dynamic system made up of said second set of said variables (W, B, C), respectively.

Operating head, particularly for a laser machine

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.
