This presentation is about the working principle of lathe machine which can be very useful for Mechanical Engineering student.

6. Theory Of Lathe Machine::
A lathe is one of the oldest and perhaps most
important machine tools ever developed. The job to
be machined is rotated and the cutting tool is moved
relative to the job. That is why; the lathes are also
called as “Turning machine”.
A lathe was basically developed to machine
cylindrical surface. But many other operations can
also be performed on lathe, for example, facing,
parting, necking, knurling, taper turning, thread
cutting and forming etc.
A lathe is called “The father of the entire machine
tool family”.

21. Turning ..
This operation is one of the most
basic machining processes. That is,
the part is rotated while a single
point cutting tool is moved parallel
to the axis of rotation.[1] Turning can
be done on the external surface of
the part as well as internally
(boring). The starting material is
generally a workpiece generated by
other processes such
as casting, forging, extrusion,
or drawing.

24. Facing ..
Facing in the context of turning
work involves moving the cutting
tool at right angles to the axis of
rotation of the rotating
workpiece.[1] This can be performed
by the operation of the cross-slide,
if one is fitted, as distinct from the
longitudinal feed (turning). It is
frequently the first operation
performed in the production of the
workpiece, and often the last—
hence the phrase "ending up".
