    • rotary In wood-working: A rotary chisel-edged cutter fastened to a cutter-head, or one of a gang of cutters so attached, used to cut away superfluous wood in shaping irregular forms, as in the manufacture of hames for harness, of fellies for wagon-wheels, of curved chair-legs, etc. A solid steel tool having rotating cutting edges, in the nature of a burring-tool or router, used in carving-machines for cutting ornamental figures in intaglio. In working upon wood with rotary cutters, the cutter-head shafts or cutter-spindles are sometimes carried by movable bearings, and guided after the manner of a tracing-point or stylus in a pantograph. In other machines the bearings of the cutter-head shafts or spindles are stationary, and the work is itself guided and moved to produce the required shape or pattern. See bur, 4 , and router. Compare also shaper and shaping-machine.
    • rotary A valve which makes complete and successive revolutions, thus alternately bringing its port or ports into continuity and discontinuity with a port or ports in its seat. This kind of valve has been but little used.
    • n rotary In electricity, a rotary converter.
