ABSTRACT:
A laser alignment control system is provided for aligning a rotational portion of a machine tool to a master part. The system includes a laser emitter that is mountable to one of the components being aligned and a photosensitive target mountable to the other components. The system further includes a data acquisition subsystem for receiving signals from the target and calculating alignment errors and required corrections for the system. The alignment procedure requires rotating the target for the laser emitter in the rotating tool holder or the master part. The target and/or the laser emitter are provided with a rotational orientation sensor operatively connected to the data acquisition subsystem and operative to produce signals identifying the rotational orientation of the target and/or laser emitter.
