Abstract: A method and an apparatus for performing mechanical operations on a workpiece secured on a first member for movement relative to a second member in at least one of three orthogonal directions at a precision in the &mgr;m range. Selectively energizable magnets are provided between the first and second members cause the first member to assume a floating state relative to the second member and to provide such movement. The second member is provided with a chamber for receiving the first member and is with openings for the controlled flow of pressurized fluid to augment the action of the magnets.

Abstract: A unique table saw having a roller mounted table operatively associated with a roller mounted carriage operatively secured to a supporting frame which allows the table and associated carriage to move outwardly from the supporting frame to allow the cutting of larger workpieces than could ordinarily be accomplished on the ordinary, conventional table saw.
