Abstract (en)
A method of reducing vibration experienced by an earth-boring tool during a drilling operation involving a combination of crushing and shear cutting a subterranean formation. The method includes setting an initial exposure of a drilling element coupled to an actuation device disposed within a blade of the earth-boring tool to be overexposed or underexposed relative to a primary cutting element disposed at a leading face of the blade by a distance within a range of about 0.5% and about 8.0% of an overall diameter of the primary cutting element, applying weight-on-bit to the earth-boring tool, causing the drilling element to retract toward the actuation device and to be underexposed relative to the primary cutting element, and in response to a drilling event, moving the drilling element relative to a body of the earth-boring tool to change a level of underexposure of the drilling element relative to the primary cutting element.
