ABSTRACT:
An X & Y orthogonal cut apparatus for scribing a pair of parallel cuts on a planar workpiece, the workpiece plane having an X-axis and a Y-axis, where the apparatus includes a laser device generating at least two beams including a first beam and a second beam, the first beam and the second beam each having an impact point on the workpiece, the first and second impact points being positioned diagonally with respect to the X and Y axes of the workpiece, and at least one actuator to move at least one of the impact points relative to the workpiece and the workpiece relative to the impact points.
