Product quality is al ways a matter of prime importance in manufacturing. It should be given parameter the highest priority in process planning. The quality of a machined part can be expressed in coordination geometrical parameters( dimension

The Lathe And Its Construction A lathe is a machine tool used primarily for producing surfaces of revolution and flat edges. Based on their purpose, construction, number of tools that can simultaneously be mounted and degree of automation, lathes-or, more accurately, lathe-type machine tools-can be classified as follows:
