Abstract: A superhard polycrystalline construction comprises a body of polycrystalline superhard material comprising a structure comprising superhard material, the structure having porosity greater than 20% by volume and up to around 80% by volume. A method of forming such a superhard polycrystalline construction comprises forming a skeleton structure of a first material having a plurality of voids, at least partially filling some or all of the voids with a second material to form a pre-sinter assembly, and treating the pre-sinter assembly to sinter together grains of superhard material to form a body of polycrystalline superhard material comprising a first region of superhard grains, and an interpenetrating second region; the second region being formed of the other of the first or second material that does not comprise the superhard grains; the superhard grains forming a sintered structure having a porosity greater than 20% by volume and up to around 80% by volume.

Abstract: A super hard polycrystalline construction comprises a body of polycrystalline super hard material, said body having an exposed working surface, a substrate attached to the body of polycrystalline super hard material along an interface and a plurality of apertures or channels. One or more of said apertures or channels extend(s) from the exposed working surface of the body into the substrate.

Abstract: A sensor system has a cutter element for a cutting tool, an interrogation transceiver operable to transmit a radio-frequency (RF) interrogation signal; and a sensor transceiver system operable to receive the RF interrogation signal and to transmit an RF response signal. The sensor transceiver system includes a signal guide medium configured to transduce between the RF interrogation signal, a guided signal in the signal guide medium, and the RF response signal. A characteristic of the RF response signal is dependent upon a condition of the signal guide medium. The cutter element includes the signal guide medium to allow the condition of the signal guide medium to depend upon a condition of the cutter element proximate the signal guide medium. A method of using the sensor system is also disclosed.
