  • Patent number: 8845247
    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.

  • Publication number: 20130265411
    Abstract: A system for inspecting a scraped surface of a workpiece performs steps of: a) capturing an image of the scraped surface to obtain a original image section; b) removing high point regions whose areas are outside of a predetermined area range to obtain a base image; c) processing pixels of the base image using a first imaging mask to generate a judgment image; d) determining whether uniformity of the high point regions in the base image conforms a standard; e) determining whether a number of the high point regions in the base image falls within a predetermined number range; and f) evaluating whether or not a portion of the scraped surface conforms with the standard based on results of determinations made in steps d) and e).
