ABSTRACT:
A method of machining simultaneously a sequence of surfaces on each of multiple sides of a workpiece, comprising: (a) supporting a plurality of rotary-driven spindles, each carrying a cutting tool, each spindle being supported by a plurality of relatively movable elements that provide for movement into and out of a predetermined sized, cubed machining space, such support providing for spindle movement having vectors along at least mutually perpendicular axes; (b) placing the workpiece in the machining space at a predetermined location; (c) actuating relative movement of the elements by use of linear motors to accurately position each spindle for simultaneous machining of first surfaces on separate sides of the workpiece; and (d) actuating the elements by use of said linear motors to reposition the plurality of spindles for simultaneous machining of other surfaces on each of the separate sides of the workpiece.
