Ultrasonic Wear Life Sensing of Ground Engaging Tools

A ground engaging assembly for an implement of a work machine that engages a work material to dig into the work material, the ground engaging assembly comprising:

• a plurality of member bodies, each member body of the plurality of member bodies extending from a leading end to a trailing end,
• each member body having an internal surface defining a cavity therein, the cavity having a concavity that faces away from the leading end along a longitudinal direction, the longitudinal direction extending from the leading end to the trailing end,
• each member body being fabricated from a ground engaging tool (GET) body material having a GET body material density;
• and
• a first wear sensing body embedded in each member body between the cavity and the leading end along the longitudinal direction, the first wear sensing body being fabricated from a wear sensing body material having a wear sensing body material density that is not equal to the GET body material density.
