Patent ID: 7977601

Claim:
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 perpendicular to the X-axis, the apparatus comprising: a laser device, the laser device generating at least two beams including a first beam and a second beam along a Z-axis orthogonal to each of the X-axis and the Y-axis, the first beam and the second beam concurrently impacting the workpiece at a first and a second impact point, the first and second impact points being positioned with respect to the X and Y axes of the workpiece plane such that a line formed by the first and second impact points has a slope of either one or negative one; at least one actuator that moves the first and second beams or the workpiece bi-directionally along the X-axis and moves the first and second beams or the workpiece bi-directionally along the Y-axis in order to move the first and the second impact points to scribe a first pair of parallel cuts along the X-axis and a second pair of parallel cuts along the Y-axis; and a controller that maintains a relative position of the first and second beams while the first and second beams are concurrently impacting the workpiece at the first and the second impact point such that the first and second impact points of the beams maintain the slope of the line at a same value during the first pair of parallel cuts along the X-axis of the workpiece plane and during the second pair of parallel cuts along the Y-axis of the workpiece plane, the second pair of parallel cuts being perpendicular to the first pair of parallel cuts.
