Yasuyuki KUROHARA 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: 11249453
    Abstract: A numerical controller that machines a workpiece to create multiple machined holes with a predetermined machining position and a predetermined machining shape in the workpiece includes a thermal influence calculation unit that determines a temporal change in a heat distribution of the workpiece for each of the machined holes when the machined hole having the machining shape is created at the machining position, a machining position determination unit that determines a next machined hole that does not cause thermal deformation of the workpiece on the basis of an elapsed time that elapses from creation of a previously machined hole to creation of a next machined hole and a heat distribution resulting from creation of the previously machined hole and the next machined hole, and a machining unit that creates the machined holes. The numerical controller can determine the machining positions taking the thermal deformation into account.

  • Patent number: 10444718
    Abstract: A program generator extracts at least one machining process from a machining program, analyzes the machining process, generates information regarding the machining process, gives the machining process a score based on the information regarding the machining process, and determines a sequence of the machining process based on the given score. The information regarding the machining process includes a machining shape to be formed by the machining process. The machining process is given a score based on the machining shape.

  • Patent number: 10427231
    Abstract: A numerical controller controlling a wire electric discharge machining device of the present invention is configured to perform perpendicular setting of the wire electrode with respect to the workpiece while the wire electrode is inserted into and passed through a machining hole of a workpiece and calculate the inclination of the workpiece; drive an XY axis and detect short-circuit; obtain the diameter of the machining start hole; subsequently drive the upper wire guide and the lower wire guide respectively and detect the short-circuit and calculate the location of the center of the upper portion of the machining start hole and the location of the center of the lower portion of the machining start hole; and, based on these calculated values, calculate the correction amount for the workpiece on the upper wire guide surface of the upper wire guide and the correction amount for the workpiece on the lower wire guide surface of the lower wire guide.

  • Patent number: 9715228
    Abstract: In restarting automatic operation after a machining program or machining conditions are changed or manual intervention is performed while the automatic operation is suspended, a machining path based on simulated operation is drawn to check the change for correctness. A drawing path of an unmachined part is reconstructed by, for example, recalculating a check drawing path at or behind a program stop position, and the reconstructed drawing path is redrawn.
