A cutting element for an earth-boring drilling tool and its method of making are provided. The cutting element may include a substrate, a superhard layer, and a sensing element. The superhard layer may be bonded to the substrate along an interface. The superhard layer may have a working surface opposite the interface and an outer peripheral surface. The outer peripheral surface may extend between the working surface and the interface. The sensing element may comprise at least a part of the superhard layer.

A sintered polycrystalline diamond material (PCD) of extremely fine grain size is manufactured by sintering under high pressure/high temperature (HP/HT) processing, a diamond powder which is blended with a pre-milled source catalyst metal compound. The PCD material has an average sintered diamond grain structure of less than about 1.0 &#x3bc;m.

Polycrystalline diamond material with extremely fine microstructures

A method of making a polycrystalline diamond compact includes mixing a diamond particle feed with a binder to form a mixture, forming the mixture into a precompact, heating the pre-compact in a non-oxidizing atmosphere to substantially drive off the binder, oxidizing the pre-compact in an oxidizing atmosphere at a temperature and for a time sufficient to burn off non-diamond carbon without overoxidizing diamond, and sintering the pre-compact at high pressure and high temperature to form a polycrystalline diamond compact. The method may also include oxidizing the diamond particle feed prior to mixing with the binder.

A method of making a near-net superhard material body includes preparing granules from a mixture of superhard powder, binders, and fluids, compacting the granules to form a soft green complex-shaped body, heating the soft green body in a furnace to form a hard green body free from residual binders, embedding one or more of the hard green bodies in a containment powder or a containment means and forming a pressure cell, sintering the cell at high pressure and high temperature, and removing the containment powder from the cell or removing the inserts from the containment means to reveal one or more near-net bodies.

Near-net cutting tool insert

A method of prolonging the life of a PDC cutter having a substantially cylindrical shape centered about a rotational axis, and an apparatus for multi-axis modulation of a PDC cutter, the method including imparting linear modulation to the cutter in at least one direction and imparting rotary modulation to the cutter about the rotational axis, the rotary modulation being synchronized with, and facilitated by, the linear modulation.

Multi-axis modulation of cutters

An cutting element incorporates a non-magnetic and electrically conductive substrate on which a layer of polycrystalline diamond particles is sintered to the substrate. An method of forming a cutting element comprises sintering the substrate, a layer of diamond particles and a catalyst source at a pressure greater than 20 kbar and a temperature greater than 1200&#xb0; C. to form a layer of polycrystalline diamond particles bonded to the substrate. Cutting elements incorporating non-magnetic and electrically conductive substrates can be sectioned using ablation techniques, such as laser cutting.

Metal-free supported polycrystalline diamond and method to form

The present disclosure relates to cutting tool edges that include on a rake face a superabrasive layer and a HPHT sintered or HPHT bonded cap layer. The cap layer improves adhesion between the superabrasive layer and an optional coating system for the cutting insert and acts as a thick anti-friction layer and/or a thermal barrier coating.

An abrasive compact may include an ultra-hard phase that may include ultra-hard particles having a Knoop hardness of 5000 KHN or greater, a sinter catalyst, and a reaction phase that may include a catalyst-ceramic compound having a Knoop hardness lower than that of the ultra-hard phase.

Abrasive compact with improved machinability

A cutting insert includes a cutting insert body having a plurality of openings, a plurality of cutting tips, and a braze joint between each of the cutting tips and the cutting insert body. Each of the cutting tips may be disposed in a respective opening of the insert body. The cutting tips include an intermediate feature and a tip portion. The intermediate feature has a geometry that provides a mechanical bond when inserted into an opening of the cutting insert body.

Cutting tool inserts and methods to manufacture

The present invention relates to a die comprising a die core () of a hard material and at least two pre-stressed rings () of increasing diameter placed around the die core and methods of making and using the same. The die core () is held in place by a force generated through deformation of mating geometric features on the die and the rings () of increasing diameter.

Wire drawing die and method of making

The present invention relates to cutting tool inserts. A cutting tool insert includes an abrasive tip of a hard material, an abrasive or superabrasive material. A cutting tool insert is bonded to an insert body by mechanical force. The mechanical forces are generated through deformation of mating geometric features on the abrasive tip and insert body.

The present invention is directed to a method for changing the color of colored natural diamonds. The method includes placing a discolored natural diamond in a pressure-transmitting medium which is consolidated into a pill. Next, the pill is placed into a high pressure/high temperature (HP/HT) press at elevated pressure and elevated temperature for a time sufficient to improve the color of the diamond. The diamond may be exposed at elevated-pressure and elevated-temperature conditions within the graphite-stable region of the carbon-phase diagram&#x2014;without significant graphitization of the diamond, or above the diamond-graphite equilibrium and within the diamond-stable region of the carbon-phase diagram. Finally, the diamond is recovered from said press. Colorless Type Ia and Type II diamonds may be made by this method.

High pressure/high temperature production of colorless and fancy-colored diamonds

The present invention is directed to a method for treating discolored natural diamond, especially Type IIa diamond and Type IaA/B diamond with nitrogen as predominantly B centers, for improving its color. The method includes preblocking and preshaping a discolored natural diamond to prevent its breakage in a high pressure/high temperature (HP/HT) press, placing said discolored natural diamond in a pressure transmitting medium which is consolidated into a pill. Next, the pill is placed into a HP/HT press at elevated pressure and elevated temperature within the graphite-stable or diamond-stable range of the carbon phase diagram for a time sufficient to improve the color of said diamond. Finally, the diamond is recovered from said press. Colorless and fancy colored diamonds can be made by this method.
