System and method of constant depth of cut control of drilling tools

摘要

A method of configuring a depth of cut controller (DOCC) of a drill bit includes determining a first desired depth of cut for a first radial swath associated with a bit face of a drill bit. The first radial swath is associated with a first area of the bit face. The method further includes identifying a first plurality of cutting elements located on the bit face that each include at least a portion located within the first radial swath. The method additionally includes configuring a first depth of cut controller (DOCC) for placement on the bit face within the first radial swath. The first depth of cut controller is configured based on the first desired depth of cut for the first radial swath and each portion of the first plurality of cutting elements located within the first radial swath.

1. A method of configuring a depth of cut controller (DOCC) of a drill bit comprising:
determining a first desired depth of cut for a first radial swath associated with a bit face of the drill bit, the first radial swath having a first area on the bit face located between a first radial coordinate and a second radial coordinate; identifying a first plurality of cutting elements located on the bit face that each include at least a portion located within the first radial swath, each of the first plurality of cutting elements including a cutting edge located within a cutting zone of an associated cutting element; determining a first angular coordinate and a first radial coordinate for a first control point associated with a first depth of cut controller (DOCC) and located within the first radial swath; calculating a first axial coordinate for the first control point based on the cutting edges of the first plurality of cutting elements located within the first radial swath, the first angular coordinate of the control point, and the first desired depth of cut for the first radial swath; and configuring the first DOCC at the first control point based on the first axial coordinate for the first control point such that the first DOCC controls a first depth of cut of the drill bit at the first radial coordinate for the first control point according to the first desired depth of cut.
