Filed:

Appl. No.:

14/876205

Inventors:

- Orem UT, US
Mark P. Chapman - Provo UT, US
Brent A. Lingwall - Spanish Fork UT, US

Assignee:

US SYNTHETIC CORPORATION - Orem UT

International Classification:

G01B 5/016

Abstract:

A probe for use with measuring equipment, such as a coordinate measuring machine (CMM) or a profilometer includes a shaft and a probe tip coupled with the shaft. At least a portion of the probe tip comprises a superabrasive material such as polycrystalline diamond. The probe tip may exhibit a variety of different geometries including, for example, substantially spherical, substantially cylindrical with a high aspect (length to diameter) ratio, or substantially disc-shaped. In other embodiments, the tip may include a converging portion leading to a fine-radiussed end point. The tip may be manufactured by forming a body using a high-pressure, high-temperature (HPHT) process and the shaping the body using a process such as electrical discharge machining (EDM), grinding or laser cutting.

Assignee:

US SYNTHETIC CORPORATION - Orem UT

International Classification:

B24D 18/00
B24D 3/00

US Classification:

51307

Abstract:

Methods of laser cutting polycrystalline diamond tables and polycrystalline diamond compacts are disclosed. Laser cutting of the polycrystalline diamond table provides an alternative to electrical-discharge machining (“EDM”), grinding with a diamond wheel, or lapping with a diamond wheel. Grinding or lapping with a diamond wheel is relatively slow and expensive, as diamond is used to remove a diamond material. EDM cutting of the polycrystalline diamond table is sometimes impractical or even impossible, particularly when the cobalt or other infiltrant or catalyst concentration within the polycrystalline diamond table is very low (e.g., in the case of a leached polycrystalline diamond table). As such, laser cutting provides a valuable alternative machining method that may be employed in various processes such as laser scribing, laser ablation, and laser lapping.
