The Massachusetts Institute of Technology (MIT) was sub-contracled into this research and development by the Parsons Corporation, during the period 1949-1951, and jointly they developed the first control system which could be adapted to a wide range of cnc machine tools.
The Cincinnati Machine Tool Company converted one of their standard 28 inch "HydroTel" milling machines to a three-axis "automatic"milling machine for this contract, having removed the contouring equipment.
This machine made use of a servo-mechanism for the drive system on the axes,
which controlled the table positioning, cross-slide and spindle head. The
machine can be classified as the first truly three axis continuous path machine
tool and it was able to generate a required shape, or curve, by simultaneous
slideway motions, if necessary.
