ABSTRACT:
In a machine and method for automatically cutting a length of sheet work material segment-by-segment to separate two dimensionally shaped pieces from it, registration between lines cut in adjacent segments is enhanced by the use of X and Y coordinate sensors carried by the X beam of the machine and having X and Y wheels respectively rotatably engaging the top surface of the work material to detect displacement changes between the X beam and the work material in the X and Y coordinate directions which detections are used to slave the advancement of the X beam to the advancement of the work material and to provide X and Y coordinate offset adjustments to the X and Y sets of control signals used to drive the cutter head in the X and Y coordinate directions during the cutting of the next segment of the work material.
