The tool and the workpiece to be machined are relatively moveable toward and away from one another, and the rotary speed of a drive motor for the tool is set to a starting rotary speed which is so low that, when the tool comes into contact with the reference surface, its rotary speed is measurably reduced, the reference surface is moved past the tool before the tool is in contact and while the tool is in contact. As a result, the braking moments in the bearings are increased, and the drive motor comes to a stop quicker.

Abstract: This invention results from the realization that a drill bit can be positioned for sharpening without using the flawed tip as a reference point allowing the drill bit to be sharpened with an insignificant level of human judgment and with consistently less flawed results. This inventive method for properly positioning a drill bit to be sharpened involves selecting a drill bit with a substantially helical geometric shape, a feature common to most drill bits. The next step is viewing a drill bit with a digital imaging device. Either an individual or, preferably, a computer determines the geometric shape of the drill bit. An individual or automated mechanism then calculates a sharpening position, relative to a sharpening means, such as sharpening wheels, for sharpening the drill bit based on the geometric shape of the drill bit. Automating this step may involve calibrating the machine by first manually positioning the drill bit and then programming a machine to similarly position all similarly shaped drill bits.
