1. A fixture for a milling machine to position and manipulate related work pieces that are assembled together, comprising:
a rotary plate, said rotary plate having a first precision surface and a second precision surface; a first sub fixture, said first sub fixture being powered to rotate said rotary plate, said rotary plate mounted to said first sub fixture such that said rotary plate is rotated by said first sub fixture; a second sub fixture, said second sub fixture being able to freely rotate with said rotary plate when rotated and said second sub fixture including a brake to prevent free rotation; a tailstock plate mounted to said second sub fixture, said tailstock plate freely rotatable with said rotary plate when said rotary plate is rotated; one of a first plate fixture and a second plate fixture, said first plate fixture mounted between said rotary plate and said tailstock plate, said first plate fixture mounted to said first precision surface of said rotary plate at one end and said first plate fixture mounted to said tailstock at said second end, said first plate fixture adapted to receive a first work piece that intended to be assembled with a second work piece; said second plate fixture mounted between said rotary plate and said tailstock plate, said second plate fixture mounted to said rotary plate at said second precision surface of said rotary plate; said second plate fixture having an additional fixture mounted to said second precision surface and said tailstock; said second plate fixture adapted to receive said second work piece to be assembled with said first work piece; where the finished first and second work pieces mate together when milling is finished, and where a relationship of locations of said first precision surface and said second precision surface are know during milling to precisely locate in space where the first and second work pieces are mounted in said fixture due to the know locations of said first precision surface and said second precision surface allow for quick installation of the first and second work pieces between said first sub fixture and said second sub fixture; and said tailstock plate including a first surface for mounting of said first plate fixture with the first work piece, said tailstock plate including a second surface for mounting of said additional fixture of said second plate fixture with the second work piece, said tailstock plate capable of rotating with said rotary plate due to attachment of either work piece. |
