a reconfigurable flying cutting , notching and shaping machine operates upon a workpiece traveling along a generally linear axis of motion . the machine supports one or more flying tools upon one or more splined shafts and provides bearings for travel along a splined shaft in a direction of movement parallel to the direction of work travel . rotation of the splined shaft is coupled through a double - acting cam to move one or more flying cutting tools transversely to the splined shaft .
