METHODS OF FABRICATING CUTTING ELEMENTS FOR EARTH-BORING TOOLS AND METHODS OF SELECTIVELY REMOVING A PORTION OF A CUTTING ELEMENT OF AN EARTH-BORING TOOL

摘要

Cutting elements for use with earth-boring tools include a cutting table having at least two sections where a boundary between the at least two sections is at least partially defined by a discontinuity formed in the cutting table. Earth-boring tools including a tool body and a plurality of cutting elements carried by the tool body. The cutting elements include a cutting table secured to a substrate. The cutting table includes a plurality of adjacent sections, each having a discrete cutting edge where at least one section is configured to be selectively detached from the substrate in order to substantially expose a cutting edge of an adjacent section. Methods for fabricating cutting elements for use with an earth-boring tool including forming a cutting table comprising a plurality of adjacent sections.

1. A method for fabricating a cutting element for use with an earth-boring tool, the method comprising:
forming a cutting table comprising a plurality of adjacent sections comprising:
forming a plurality of recesses in the cutting table extending across a cutting surface of the cutting table to define the plurality of adjacent sections; andforming a discrete cutting edge on each section of the plurality of adjacent sections of the cutting table adjacent a recess of the plurality of recesses to expose the discrete cutting edge of a section of the plurality of adjacent sections upon detachment of an adjacent section.
