ABSTRACT:
The present invention is embodied in a self leveling system for sensing and changing the inclination of generally horizontal members of a jig frame assembly that includes a manufacturing plane, which system includes a lifting means affixed generally under an end of one of the horizontal members, a level sensing means affixed to the member for sensing an inclination of the member, and a computer comprising means to input a desired orientation of the manufacturing plane with respect to the horizon, means to compare the sensed inclination of the horizontal member with the desired orientation, means to compute a change in the sensed inclination to achieve the desired orientation, and means to transmit a control signal proportional to the change to the lifting means for the purpose of achieving the desired orientation of the manufacturing plane.
