Continously adjusting resultant force in an excavating assembly |
摘要 |
In one aspect of the present invention, a method of excavation with pointed cutting elements, comprising the steps of providing a excavating assembly with at least one pointed cutting element, the pointed cutting element comprising a rounded apex that intersects a central axis, the pointed cutting element further has a characteristic of having its highest impact resistance to resultant forces aligned with the central axis; engaging the at least one pointed cutting element against a formation such that the formation applies a resultant force against the pointed cutting element; determining an angle of the resultant force; and modifying at least one excavating parameter to align the resultant force with the pointed cutting element's central axis.
