1. A process for producing a monolithic part comprising the steps of:providing a piece of stock; rough machining the piece of stock, leaving sufficient material to provide for finish machining; forming the piece of stock, initially over forming the piece of stock beyond a final desired contour followed by forming the piece of stock to the final desired contour; clamping the formed piece of stock for semi-finish machining, and semi-finish machining the piece of stock; releasing the piece of stock, thereby allowing the piece of stock to find a neutral position; reclamping the piece of stock; and finish machining the piece of stock. 2. The process according to claim 1, further comprising releasing, deburring and applying finish treatments to the piece of stock.3. The process according to claim 2, wherein said steps are performed in the order recited.4. The process according to claim 1, further comprising machining gauge points and attachment features into the piece of stock.5. The process according to claim 1, wherein the piece of stock is over formed beyond its intended final shape, then formed back to its final shape.6. A process for producing a monolithic part comprising the steps of:providing a piece of stock, rough machining the piece of stock; forming the piece of stock; clamping the formed piece of stock for semi-finish machining, and semi-finish machining the piece of stock; releasing and reclamping the piece of stock; and finish machining the piece of stock; wherein the monolithic part comprises a skin portion and a support frame portion. 7. The process according to claim 6, wherein the skin portion and support frame portion are integral.8. A process for forming a monolithic part comprising:providing a work piece; rough machining the work piece leaving sufficient material for finish machining; over-forming the work piece through cold forming, wherein the work piece is overformed; forming the over-formed work piece to a desired shape to reduce residual stress occurring in the over-formed shape; and finish machining the work piece using high velocity machining. 9. The process of claim 8, further comprising:semi-finish machining the work piece prior to finish machining the work piece; releasing the work piece after semi-finish machining; and reclamping the work piece prior to finish machining. 10. A process for forming a monolithic part comprising:providing a work piece; rough machining the work piece leaving sufficient material for finish machining; over-forming the work piece through cold forming, wherein the work piece is overformed; forming the over-formed work piece to a desired shape to reduce residual stress occurring in the over-formed shape, wherein forming the work piece includes utilizing a hydraulic brake; and finish machining the work piece using high velocity machining. 11. A process for forming a monolithic part comprising:providing a work piece; rough machining the work piece leaving sufficient material for finish machining; over-forming the work piece through cold forming, wherein the work piece is overformed; forming the over-formed work piece to a desired shape to reduce residual stress occurring in the over-formed shape; and finish machining the work piece using high velocity machining; wherein the work piece includes an inner surface having integrated ribs and integrated stringers, wherein the ribs and the stringers have residual stress levels within predefined parameters.
