摘要： The invention relates to a method and a device for electrochemically processing a material, which contains a hard phase and a binder phase. The method comprises preparing an aqueous, alkaline, complexing-agent-containing electrolyte and bringing the material to be processed into contact at least in part with the electrolyte and with a current source. In order to electrochemically oxidize the material, a pulsed electrical current is delivered to the material by means of the current source, the pulse sequence of the delivered electrical current being adjusted to the amount of the binder phase in the material to be processed. By means of the method and by means of the device, it is also possible to process materials having a high content of binder phase in such a way that matter can be removed from the material evenly (homogeneously), i.e. both from the hard phase and from the binder phase of the material.

摘要： A wire electrical discharge machine includes: a travelling route formed of multiple divisional regions, through which a wire electrode is fed by an auto wire feeding mechanism; and a memory storing failure evaluation reference data on the auto wire feeding for every divisional region. The wire electrical discharge machine detects failure of the auto wire feeding and locate the tip position of the wire electrode at the time of failure and causes a controller to determine whether to perform or stop retry of the auto wire feeding based on the located tip position and the failure evaluation reference data for every divisional region.

摘要： A measurement system is for measuring positions of a plurality of subjects by using an ultrasonic testing sensor. The measurement system includes an ideal arcuate waveform creation unit configured to create, for each of the subjects, an ideal arcuate waveform of a measurement result of the ultrasonic testing sensor based on machining position information on the subject; a measurement arcuate waveform creation unit configured to create a measurement arcuate waveform based on the measurement result; a position estimation unit configured to collate the ideal arcuate waveform and the measurement arcuate waveform with each other to estimate a position of the subject from the measurement arcuate waveform determined to correspond to any ideal arcuate waveform; and an antiphase waveform addition unit configured to add, to the measurement arcuate waveform, a waveform in antiphase to the measurement arcuate waveform with which the position of the subject has been estimated.

摘要： An electrochemical machining device includes a plurality of electrodes, a guiding member and a plate member. The electrodes are disposed around a workpiece. The guiding member is configured to limit and guide each of the electrodes to move. The plate member is configured to exert a force to each of the electrodes. The driving member is configured to rotate the workpiece. The plate member is connected to each of the electrodes. A force-exerting direction of the force from the plate member to each of the electrodes is parallel to a central axis of each of the electrodes or deflects off the central axis. Each of the electrodes is passed through the guiding member and configured to perform a machining on the workpiece which is rotated by the driving member, and each of the electrodes has an electrochemical machining direction which is perpendicular, oblique or parallel to the workpiece.
