A flexible fastening machine tool having first and second facing pedestals is mounted on first and second pairs of rails. The pedestals are movable along the rails in a Y-axis direction. A rail base is provided and the second pair of rails is mounted on the rail base. A third pair of rails that extend in an X-axis direction are mounted to the floor, and the rail base is positioned on the third pair of rails, such that the second pedestal is movable along the third pair of rails in the X-axis direction toward and away from the first pedestal. A first movable carriage is mounted on the first pedestal and a second movable carriage is mounted on the second pedestal. A frame member is supported by the first and second carriages and the frame member holds a workpiece. The first and second carriages are independently movable toward and away from the first and second pairs of rails such that the fixture frame is capable of being raised, lowered and tilted. A C-frame is mounted on the third pair of rails and the C-frame is capable of performing tooling operations on the workpiece.
