Cutting element with a non-shear stress relieving substrate interface
Abstract:
The present invention includes an improved cutting element substrate for cutting elements. The cutting element substrate includes non-planar, non-linear interfaces with an abrasive layer of superhard material affixed thereto often using a high pressure high temperature press apparatus. The cutting element substrate includes a cant intersecting a first and second interfacial surface. A plurality of truncated nodules intersects the first surface and extends towards the second surface. Arcuate segments protrude out of the second surface and are radially positioned along the surface. The truncated nodules are ill-aligned with the arcuate segments proximate the truncated nodules.
