Abstract
A vibrating gyroscope is mounted on a cutting device. The vibrating gyroscope is heated by halogen lamps, and a drift due to temperature variation is measured by a drift measuring device. Resonance frequencies in plural directions of the vibrating gyroscope are measured by a frequency measuring device. A cutting quantity of a vibrating body of the vibrating gyroscope is calculated from the drift due to a temperature variation and a difference of plural resonance frequencies by a control device. The cutting quantity of the vibrating body is decided by deliberating the cutting quantity obtained experientially. When the cutting quantity of the vibrating body is decided, rotating bar files are pressed against the vibrating body responsive thereto, thereby the vibrating body is cut.
