The document discusses the key parameters and specifications of a lathe machine. It describes the main components of a lathe including the head stock, spindle, bed, tail stock, and carriage. It lists the main turning parameters as speed, feed, and depth of cut. It then details five main specifications of a lathe: 1) the length between centers, 2) the height of the centers, 3) the swing diameter over the bed, 4) the swing diameter over the carriage, and 5) the maximum bar diameter.
