Abstract: An automated drill bit sharpening and verification system employing one or more electronic optical assemblies for gathering orientation data of a drill bit to be sharpened. The drill bit is rotated and aligned to a grinding assembly based on the orientation data. The orientation data of the drill bit may be gathered by illuminating a cutting tip of the drill bit with an illumination ring. Additionally, the orientation data of the drill bit may be gathered by capturing two views (e.g., orthogonal views or front and side views) of the cutting tip of the drill bit.

Abstract: A completely automated apparatus for verifying the identity and geometry of drill bits, re-sharpening the cutting tip of a drill bit and re-positioning a locating ring upon the shank portion of the drill bit subsequent to the re-sharpening of the cutting tip thereof. The apparatus comprises a housing having a pair of cassette trays, a pair of grinding assemblies, a pair of optical assemblies, a pair of primary cleaning assemblies, a pair of secondary cleaning assemblies, a pair of inversion assemblies, a pair of workhead assemblies, a bumping assembly, and a loader assembly attached thereto. The workhead and loader assemblies are used to transport drill bits between the cassette trays and other assemblies in a selected sequence which is controlled and coordinated by a programmable control device. The control device is electrically interfaced to each of the assemblies and allows the cutting tip re-sharpening and locating ring re-positioning processes to be conducted simultaneously on at least two drill bits.
