20140109421 | METHOD AND DEVICE OF INSPECTING WORKPIECE FOR PROCESSING MACHINE - A method of inspecting a workpiece for a processing machine includes the steps of placing a workpiece on a worktable, moving a spindle located above the worktable to allow a laser sensor mounted with the spindle to be close to the workpiece, measuring a distance between the laser sensor and the workpiece by a laser beam emitted from the laser sensor on the work piece, and gathering data of the workpiece, such as size, shape or location, by moving the spindle to enable the laser beam to pass through the periphery of the workpiece. | 04-24-2014 |
