ABSTRACT:
A machine tool operated by gyroscopic precession is disclosed. The machine tool is provided with a rotatable member disposed for rotation in a single plane, the member mounted to a base. A gyroscopic mass supported by a gimbal is mounted to the rotatable member so that the spin axis of the gyroscopic mass, in a null position, is parallel to a plane of rotation of the rotatable member. A sensor is provided for sensing position of the rotatable member, the sensor providing a control input to a computer, which in turn develops a drive signal for driving an actuator coupled to the gimbal. When the actuator is activated by the drive signal, the gimbal is displaced, precessing the gyroscopic mass and generating a force used to rotate the rotatable member.
