  • POWDER METAL NET SHAPE ALIGNMENT FEATURE
    Publication number: 20180031115
    Abstract: A powder metal component for a transmission includes a body portion defining a substantially planar major surface, and at least three radially spaced-apart retention features formed in the body portion in a green state, prior to sintering. Each retention feature may include a bore having a shaped geometry extending between an upper region adjacent the major surface of the body portion, and a lower region defining a radius of curvature. Each bore may be defined by two opposing, substantially parallel sidewalls and a substantially U-shaped bottom portion. The U-shaped bottom portion may include a center region defining the radius of curvature connecting two angled bottom walls.
