|20110120981||LASER MACHINING MACHINE - A machine for machining workpieces by a laser beam. The optical fibre terminates at an optical output head (||05-26-2011|
|20110062118||METHOD AND MACHINE FOR MACHINING PARTS USING SPARK-EROSION MILLING - Spark-erosion machining method and machine implementing a machining gap, a process regulator, a numerical control system, a Nominal Trajectory. The latter describes the movement of the tool electrode relative to the part as it ought to proceed if no disturbance were to occur during the machining. Information contained in the Nominal Trajectory is used to define at least two control vectors Vg, Vp which orient, within the coordinate system XYZ, two independent regulation movements. The first, or Gap Vector Vg, defines the direction in which a first regulation movement of the axes of the machine must be performed to maintain the removal of material. The second, or Position Vector Vp, defines the direction in which a second regulation movement of the axes of the machining machine must be performed to correct a tool electrode position error. The respective amplitudes of the regulation movements are calculated in real time by the process regulator.||03-17-2011|

|20100096364||METHOD AND APPARATUS FOR CONTROLLING AN ELECTRIC DISCHARGE MACHINING PROCESS - A method for controlling an electric discharge machining process, wherein a tool electrode is moved relatively to a workpiece with a working gap distance, wherein the process includes a current and at least one previous erosion cycle, the current and the previous erosion cycle each being divided into predetermined time intervals each including at least one discharge pulse, wherein similar working gap conditions are present within a time interval of the previous erosion cycle and of the current erosion cycle, and wherein subsequent erosion cycles are separated by a process pause cycle.||04-22-2010|
|20090230091||DEVICE DESIGNED TO CUT OFF THE SPENT WIRE ON A SPARK EROSION MACHINE - Cutting device for spark-erosion machine wires in which, after passing through a machining region, the wire-electrode is cut up into sections which are disposed of as waste products into a recovery receptacle. The device comprises electrical contacts connected to a voltage/current source. The wire is subjected to a dielectric fluid whose flow rate is sufficiently high to generate a turbulent flow regime and cause random lateral movements of the wire which sporadically brushes against the contacts.||09-17-2009|
