Patents by Inventor Fabrizio Robbiani

Fabrizio Robbiani has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5984506
    Abstract: A control device for controlling a machine tool includes at least one memory for storing control data characterizing the instantaneous operating state of the machine tool during machining and a memory management device for managing the control data such that machining can be resumed after an interruption. The control data is separated into dynamic control data and static control data. The method for controlling a machine tool uses the control device and stores the static and dynamic control data in the memory. As a workpiece is machined, the instantaneous operating state of the machine tool is continuously stored so that machining can be resumed after an interruption.

  • Patent number: 5940301
    Abstract: The invention pertains to a method and a device for controlling a machine tool, in particular an EDM machine, wherein the control data necessary for machining one or more workpieces is fed from the control device to the machine tool. Therein a list of action data for controlling special procedures (actions) and a list of event data for characterizing prescribed operating states (events), in particular, malfunctions, are permanently provided. The action and event data are linked in setting up the machine such that upon occurrence of one or more events, one or more actions are performed.

  • Patent number: 4939334
    Abstract: In order to avoid unnecessarily long withdrawal movements and to eliminate as rapidly as possible short-circuits upon contact of a countersinking electrode with the workpiece being worked in the electroerosion machine, whilst also adapting as flexibly as possible the path of the withdrawal movement to the geometry of the workpiece to be eroded and the path eroded therein, the withdrawal movement of the countersinking electrode during a short-circuit is controlled so that in the presence of a short-circuit the countersinking electrode is initially moved back by a predetermined distance along the previously covered or eroded path from a short-circuit point to an intermediate point and then the electrode is moved away from the intermediate point over the given withdrawal path if there is still a short-circuit on reaching the intermediate point.
