  • Patent number: 9205525
    Abstract: A method and a system, for offsetting measurement of machine tool, includes following steps. A tool seat is chosen, a first coordinate is set based on a first datum mark of the tool seat. There is a total tool seat assembling length in between the first datum mark and the tool seat. A tool is chosen, assembled in the tool seat, and includes a total tool length. A second coordinate is set based on a second datum mark of a measuring unit. The tool seat is moved to make a machining end of the tool contact with the second coordinate to obtain a relative total length in between the first and the second coordinate. The total tool length subtracts from the relative total length equals an assembled offset length. The total tool seat assembling length subtracts from the relative total length equals and obtains a tool assembling length.

  • Publication number: 20140188425
    Abstract: A method for selecting fans for a server cabinet includes the following steps. First, a type of fan stored in a database is selected, and the parameters related to the fan of the selected type are compared to input parameters of a server cabinet. Second, a maximum quantity of the fan of the selected type that can be accommodated in the server cabinet is calculated. Third, an airflow of an initial quantity of the fan of the selected type is calculated when the initial quantity of the fan of the selected type is determined to be less than the maximum quantity. Fourth, the initial quantity of the fan of the selected type and the related parameters of the fan of the selected type are output to a display if the calculated airflow is determined to be greater than or equal to a minimum required airflow of the server cabinet.

  • Publication number: 20140083980
    Abstract: An apparatus for electrical discharge machining modulation control includes an EDM module, an open-circuit voltage modulation module, a reference-voltage modulation and judgment module, a database, and a control unit. The control unit selects a reference voltage, and an open-circuit voltage corresponding to characteristics of a workpiece from the database, and generates and transmits a second control signal to the open-circuit voltage modulation module for modulating the open-circuit voltage, and a third control signal to the reference-voltage modulation and judgment module for modulating the reference voltage utilised to determine if the ignition happened. The open-circuit voltage modulation module receives a first control signal periodically transmitted from the control unit for providing the open-circuit voltage to the EDM module.

  • Publication number: 20120152907
    Abstract: A self-adjusting power device for high efficiency electrical discharge machining and method thereof is disclosed. A high-voltage arc unit and a low-voltage discharge unit provide a high voltage arc pulse and a low voltage discharge pulse to an electrode respectively. The electrode machines a workpiece and feeds back a gap voltage to a discharge pulse generation unit. The discharge pulse generation unit determines whether the gap voltage is lower than a predetermined voltage or not. If yes, a discharge channel between the electrode and the workpiece is conducted, and the discharge pulse generation unit shuts down the high-voltage arc unit and the low-voltage discharge unit is still operating at ON time and shuts down at OFF time. If no, looping the determination of the discharge pulse generation unit. Therefore, discharge machining energy is accurately controlled and high efficient power saving is achieved.
