  • A lathe is a machine tool which spins a block of material to perform various operations such as cutting, Turning, Facing, Threading, sanding, knurling, drilling, or deformation such as metal spinning with tools that are applied to the work piece to create an object which has symmetry about an axis of rotation .Lathe Machine: • The term Centre Lathe is derived from the fact that in its operation the lathe holds a piece of material between two rigid supports called centres, or by some other device such as a chuck or faceplate which revolves about the centre line of the lathe. .Lathe...

  • Gyroscopic precession is a key factor involved in the concept of operation for the north-seeking gyrocompass, as will be discussed later. Friction in the support bearings, external influences, and small imbalances inherent in the construction of the rotor cause even the best mechanical gyros to drift with time. Typical systems employed in inertial navigation packages by the commercial airline industry may drift about 0.1 during a 6-hour flight [Martin, 1986]. 2.1.
