Document Type and Number:
WIPO Patent Application WO2006012051
Kind Code:
A3
Abstract:
Electrically powered devices are provided that are generally capable of automatically adjusting an operating speed of a tool removably connected to the device. The device includes circuitry that evaluates tool wear for the tool removably connected to the device, produces a tool wear signal based on the tool wear, and adjusts the operating speed of the tool based on the tool wear signal. The device may further be capable of automatically setting the initial operating speed of the particular tool removably connected to the device by identifying the particular tool and setting the initial operating speed which may later be adjusted to account for tool wear.
