Abstract
A laser beam position control apparatus for a CNC laser equipped machine tool, that will automatically maintain precise alignment of the beam path, though the machine may be operating in a non-uniform temperature environment. The apparatus compensates for small deviations in flatness of machine mounting surfaces by steering the laser beam. The laser beam control apparatus includes a laser beam position sensor for mounting in the beam path of the machine tool and that communicates with a signal processor that in turn communicates with at least one drive apparatus that controls at least one actuator capable of moving an object to steer the laser beam.
