  • Piston skirt turning tool and method
    Patent number: 6666118
    Abstract: A single point turning tool has a tip including a cutting edge with a tip radius and a linear portion added on one side of and slightly behind the point to form a cutting edge with a linear portion and a protruding portion. The protruding extends beyond the plane of the linear portion which, in turn, extends normal to a longitudinal axis on which the tip radius is centered. During manufacture of a piston, the turning tool is positioned with the linear portion aligned generally with the plane of the finished outer surface. The piston is turned while the tool cuts a helical path or turn around the skirt surface by advancing the tool each turn a desired dimension or lead that is greater than the width of the protruding portion but not greater than the combined widths of the linear and protruding portions.
