Abstract:
A control system of a milling machine is disclosed. The milling machine has an overarm, a spindle connected to a cutter, a spindle motor, and an X-axis motor, a Y-axis motor and a Z-axis motor. The control system includes a vibration sensor for detecting a vibration level of the spindle. The control system also includes a central control unit configured to adjust a rotation speed of at least one of the X-axis motor, the Y-axis motor, and the Z-axis motor to bring a load current of at least one of the motors to be within a corresponding current range, and configured to adjust a rotation speed of the spindle motor to bring the vibration level to be within a vibration range.
Abstract:
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.

Abstract:
A method of automatic task execution is adapted to be performed by an electronic apparatus that includes an image-capturing module and a processing module. The method includes the steps of: a) recording in the processing module a relationship between a visible physical attribute of an object and a corresponding task to be executed by the processing module; b) configuring the electronic apparatus for capturing an image containing a target using the image-capturing module; c) configuring the processing module to determine if the visible physical attribute of the object is found in the image captured by the image-capturing module; and d) when the visible physical attribute of the object is found in the image, configuring the processing module to execute the corresponding task automatically.
