Abstract:
1. An automated method of re-sharpening a drill bit having a shank portion and a fluted portion which defines a pair of margins and a cutting tip using an automated re-sharpening apparatus which includes at least one grinding assembly and first and second electronic optical assemblies, the method comprising the steps of: positioning the first electronic optical assembly forward of the cutting tip of the drill bit; positioning the second electronic optical assembly on a side of the drill bit; conducting an initial evaluation of the drill bit with the first and second electronic optical assemblies wherein data gathered by the first and second electronic optical assemblies is used to determine an angular position of the drill bit; aligning the cutting tip of the drill bit to the grinding assembly based on the data gathered by the first and second electronic optical assemblies; and grinding the cutting tip via the grinding assembly.
