A system for fixturing a work piece for transforming the work piece to a machined object by performing a machining operation by one or more CNC machines on the work piece, where each CNC machine has a programmed movement of a tool with respect to the work piece or the work piece with respect to the tool, the system comprising: a. a fixture, said fixture being repeatably attachable to each of the one or more CNC machines, said fixture being configured for attachment to the work piece to define a single rigid assembly, said fixture being configured to support the work piece during the machining operation when said fixture is repeatably attached to each of the one or more CNC machines; b. a measuring apparatus, said measuring apparatus being configured to generate measurements of the work piece; c. a positioner capable of supporting the work piece or the fixture or the work piece and the fixture and moving the work piece, the fixture or the work piece and the fixture; d. a computer, said computer being operably attached to said measuring apparatus and to said positioner, said computer being configured to receive said measurements of the work piece from said measuring apparatus, said computer being configured to determine an adaptive position of the work piece with respect to said fixture, said adaptive position being a location and an orientation of the work piece with respect to the fixture in which an interior volume of the machined object will be disposed within an interior volume defined by the work piece when the work piece is attached to said fixture and said fixture is repeatably attached to the one or more CNC machines and the one or more CNC machines perform said machining operation on the work piece, said computer having a configuration to direct said positioner to move the work piece to said adaptive position with respect to said fixture for attachment of the work piece to said fixture, said positioner being configured to move the work piece to said adaptive position with respect to said fixture as directed by said computer. a. a fixture, said fixture being repeatably attachable to each of the one or more CNC machines, said fixture being configured for attachment to the work piece to define a single rigid assembly, said fixture being configured to support the work piece during the machining operation when said fixture is repeatably attached to each of the one or more CNC machines; b. a measuring apparatus, said measuring apparatus being configured to generate measurements of the work piece; c. a positioner capable of supporting the work piece or the fixture or the work piece and the fixture and moving the work piece, the fixture or the work piece and the fixture; d. a computer, said computer being operably attached to said measuring apparatus and to said positioner, said computer being configured to receive said measurements of the work piece from said measuring apparatus, said computer being configured to determine an adaptive position of the work piece with respect to said fixture, said adaptive position being a location and an orientation of the work piece with respect to the fixture in which an interior volume of the machined object will be disposed within an interior volume defined by the work piece when the work piece is attached to said fixture and said fixture is repeatably attached to the one or more CNC machines and the one or more CNC machines perform said machining operation on the work piece, said computer having a configuration to direct said positioner to move the work piece to said adaptive position with respect to said fixture for attachment of the work piece to said fixture, said positioner being configured to move the work piece to said adaptive position with respect to said fixture as directed by said computer.
