ABSTRACT:
A laser beam positioning device for a laser processing equipment includes a beam scanning unit that scans a laser beam to process a work piece according to a command value; a measurement unit that measures a processed position on the work piece; and a control unit that calculates the command value from coordinates of the processed position and coordinates of a target position. The control unit calculates an unknown parameter matrix, which optimally determines the command value to guide the laser beam onto the target position on the work piece, by weighting the coordinates of the processed position and the command value, according to a distance between the coordinates of the target position and the coordinates of the processed position.
