Title:
ACOUSTIC EMISSION TOUGHNESS TESTING FOR PDC, PCBN, OR OTHER HARD OR SUPERHARD MATERIAL INSERTS
Document Type and Number:
WIPO Patent Application WO/2014/130318
Kind Code:
A3
Abstract:
An acoustic emissions testing device includes a test cutter including a first surface, an acoustic sensor, an indenter coupled to the first surface, and a load. The load is exerted on the indenter, which transfers the load to the first surface. The acoustic sensor is communicably coupled to the test cutter and detects one or more acoustic events occurring therein. An acoustic emissions testing system includes a data recorder coupled to the testing device. The data recorder records the data from testing device. Based upon the data received, the toughness of the test cutter is objectively determined and can be ranked comparatively to the toughness of other test cutters. The load is ramped up to a peak load, held for a period of time, and then ramped down. Cutters from the same cutter type as the test cutters have similar toughness.
