Ro-bust P2P System to Handle Flash Crowds

An apparatus which includes a base frame, a workpiece-supporting rotatable chuck mounted on the base frame, a cross-slide movably mounted on the base frame and a rotatable workhead mounted on one end of the cross-slide. One or more pairs of radially opposed cutting tools are adjustably mounted on the workhead, the axis of rotation of the workhead being normal to the axis of rotation of the workpiece-supporting chuck. Facing tools are also mounted on the opposite end of the cross-slide. A control system is provided to automatically and precisely control the operation of the various tools. The radially opposed cutting tools are adapted to be moved radially inward to engage the rotating workpiece and while so engaging the workpiece, are revolved about the axis of rotation of the workhead thus generating a spherical surface on the workpiece.
