A heel shroud includes a bottom leg, and a side leg extending orthogonally from the bottom leg, forming an interior corner with the bottom leg. The heel shroud defines a first lateral surface, a second lateral surface, and the bottom leg includes a curved interior surface extending from the first lateral surface to the second lateral surface at least partially forming the interior corner. The first lateral surface defines a stress reduction geometry positioned at the interior corner, or includes a wear member that is attached to the side leg, or the bottom leg.

A method for determining part wear, such as using a wear metric, includes receiving, from a sensor, sensor data representing a surface of a wear part. The method further includes determining distances between measured points in the sensor data and points on one or more part models, which part models may include new part models and/or worn or wear limit part models. The method further includes using a bounding model that at least partially envelopes the part model(s) and the measured points to determine a direction along which the distances are measured. The method may also include quantifying wear using the measured distances.

A ground engaging tool assembly includes a ground engaging tip, an adapter, and a wear cap. The ground engaging tip has a ground engaging portion and a coupling portion including an interior surface defining a coupler pocket with an adapter opening and first and second lug openings. The adapter includes a mounting nose with first and second retention lugs extending from sides of the mounting nose along oblique taper angles. The mounting nose is disposed within the coupler pocket of the ground engaging tip with the first and second retention lugs extending into the first and second lug openings, respectively. The base includes a shoulder surface and a retention surface that define a mounting groove therebetween. The wear cap includes a mounting rail that is disposed within the mounting groove of the adapter to mount the wear cap thereto.
