1. A machining station for machining parts from a sheet metal workpiece, comprising:

  • a pair of parallelly-spaced table beams for supporting said sheet metal workpiece therebetween;

    an upper carriage beam, positioned transversely across said table beams in a manner so that said upper carriage beam is positioned above said workpiece;

    a spindle carriage mounted to said upper carriage beam, in a manner so as to be movable therealong, said spindle carriage carrying a cutting tool that is operable to machine said sheet metal workpiece, and said spindle carriage being further operable to vertically adjust the position of said cutting tool relative to said workpiece;

    an upper clamp carriage also mounted to said upper carriage beam, but in a manner so as to be movable along said carriage beam independently of the movement of said spindle carriage, said upper clamp carriage carrying a downwardly-thrusting clamping tool that is operable to stabilize the position of at least a portion of said workpiece relative to said machine tool from a location above said workpiece;

    a lower carriage beam, also positioned transversely across said table beams, but in a manner so as to be normally below said workpiece; and

    a lower clamp carriage mounted to said lower carriage beam, in a manner so as to be movable along said lower carriage beam independently of the movement of said spindle carriage and said clamp carriage which are mounted to said upper carriage beam, said lower clamp carriage carrying an upwardly-thrusting clamping tool that is operable to stabilize said workpiece from a position that is below the same.
