Abstract: A display method includes: converting, by a fitting unit, a position information into a fitting parameter; constructing, by the fitting unit, a first pattern from the position information; constructing, by the fitting unit, a second pattern from the fitting parameter; calculating, by a calculation unit, an offset information between the first pattern and the second pattern; integrating, by an integration unit, the fitting parameter of the fitting unit and the offset information of the calculation unit into a reference information; and constructing, by the integration unit, a third pattern from the reference information. In a human-machine interface applying the display method, when a user enters an amount of tolerance into the human machine interface, the machining path represented by the third pattern is reproduced on the human machine interface. Thus, the display method can simplify operations of processing the machining path and reduce the load on the memory.

Abstract: A management method for a cutting tool of a machine tool is provided. A user host imports a graphical data of a workpiece and a cutting tool database into CAM, and a user may select cutting tools to establish a complete machining process. T codes are replaced with electronic tags. Before executing a machine code comprising the electronic tags, the machine tool re-scans the cutting tools assembled at a tool turret and updates cutting tool arrangement information to ensure that the tool turret is equipped with the cutting tools used in the machining process. When the machine tool stores the electronic tags, a ready message is displayed for reminding an operator. When the electronic tags are not stored, the current storage location of a cutting tool lacked in the machining process or a warning message is displayed at the operation interface for reminding the operator.

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 utilized 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. The reference-voltage modulation and judgment module performs an arc voltage measurement procedure, then the control unit determines the open-circuit voltage and the reference voltage.

Abstract: A machine tool collision avoidance method includes: loading multiple processing codes; simulating multiple path traces corresponding to the processing codes; estimating multiple execution periods for running the path traces; selecting the shortest execution period from the execution periods; determines whether the distance between the trace point points on any two of the path traces is less than a safety distance within the shortest execution period; if the distance between a first trace point on a first path trace and a second trace point on a second path trace is less than the safety distance, estimating a first time point at which a first turret runs to the first trace point and a second time point at which the second turret runs to the second trace point; generating a collision warning if the difference between the first time point and the second time point is lower than a tolerance value.

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.
