  • Patent number: 10094652
    Abstract: A laser projection method including the steps of: irradiating, from a laser projection unit, a workpiece that is a measurement object, with a laser while controlling a plurality of mirror angles; imaging the workpiece with a stereo camera, extracting a contour of the workpiece, and calculating a three-dimensional coordinate; calculating a positional relationship between the laser projection unit and the workpiece by comparing the calculated three-dimensional coordinate of the workpiece contour with the minor angle; and performing coordinate transformation of CAD data information and drawing CAD data from the laser projection unit to the workpiece, based on the positional relationship between the laser projection unit and the workpiece. The machining method including the steps of: selecting a component of a tool; assembling the component; imaging the tool assembled; and determining whether or not a desired tool has been assembled.

  • Patent number: 9547301
    Abstract: In order to easily verify an operation of the machine tool, a machining support apparatus includes a machining monitoring unit 112, a simulation processing unit 113, and a display unit 150. The machining monitoring unit 112, upon receiving a notification indicating detection of a simulation start code programmed in a machining program from a machine tool controller controlling a machine tool via a communication device 130, renders the machine tool controller to stop the machine tool. The simulation processing unit 113 simulates instructions from the simulation start code to a simulation end code in the machining program, while the machine tool is stopped. And the display unit 150 displays a simulation performed in the simulation processing unit.

  • Publication number: 20090013278
    Abstract: A control unit revises a work order skeleton in a work order skeleton holding section and work procedure explanatory information in a work procedure explanatory information holding section based on revision information, if the revision information is held in the work order skeleton holding section or the work procedure explanatory information holding section. The control unit then makes a creation unit create revised electronic work instruction contents and send the contents to a display/voice guidance unit. The display/voice guidance unit displays an image or produces a voice guidance based on the electronic work instruction contents.

  • Patent number: 6912445
    Abstract: A method for detecting shapes that are undesirable for efficient processing and which occur from tolerance conversion by comparing a geometric relationship of shape elements obtained from shape data before tolerance conversion with a geometric relationship of the shape elements obtained from shape data after tolerance conversion. An inappropriate shape is identified when the compared geometric relationships are not the same.
