    摘要: A milling machine has a base, a work platform mounted movably on the base, and a ruler mounted on the work platform. The work platform is movable relative to a base axis. The thermal compensation system includes a sensor and a control unit. The sensor is configured to be mounted on the base for sensing a position of each of the work platform and the ruler relative to the base axis. The control unit is coupled to the sensor, and determines a work platform displacement and a ruler displacement according to the positions sensed by the sensor. The control unit further calculates a compensation value based on the work platform displacement and the ruler displacement. The control unit is configured to correct the position of the work platform relative to the base axis according to the compensation value.

    摘要: In a machine tool which includes a rotary shaft configured to allow a tool or a workpiece to be attached thereto, a driving unit for causing the rotary shaft to rotate is regulated to change a rotation speed of the rotary shaft in such a manner that the rotation speed oscillates with a given amplitude and a given period with respect to a given mean rotation speed, so that chatter vibrations can be suppressed. A parameter display control unit configured to cause a display device to display parameter information related to predetermined parameters for changing at least one of the mean rotation speed, the amplitude and the period is provided so that the parameters can be changed based upon the parameter information displayed in the display device.

    摘要: A cutting plotter includes a medium supporter, a first guide rail, a second guide rail, a carriage, a work tool, a working controller, and a second direction displacement detector. The second direction displacement detector is configured to measure a second guide rail displacement amount. The second guide rail displacement amount indicates a magnitude of displacement of a moving path of the carriage from a predetermined moving path with respect to the second guide rail in a direction perpendicular to a second direction when the carriage is moved in the second direction along the second guide rail. The working controller is configured to execute a control in which a movement control of the second guide rail on the first guide rail is added so that the second guide rail displacement amount is corrected in a movement control of the carriage on the second guide rail.

    摘要: In a device for protecting a work spindle (2) that is rotatably supported in a spindle head (4A, 4B) of a processing machine and/or a tool (3) clamped in the work spindle (2) from collisions with obstacles in the processing chamber (1) of the processing machine, a plurality of distance sensor modules (6) are arranged on or in a spindle nose (4B) that forms the termination of the spindle head (4A, 4B) toward the processing chamber (1) such that they point toward the processing chamber (1) and are connected to a common signal processing unit (8). When an obstacle is present in a predetermined area of the processing chamber (1), this signal processing unit generates a warning signal based on the measuring signals delivered by the individual distance sensor modules (6). An output (15) of the signal processing unit, at which the warning signal is generated, is connected to the machine control (16) of the processing machine. The distance sensor modules (6) preferably consist of radar or ultrasonic sensor modules.
