"Water is a precious asset given by God. While ensuring the conservation,
planned management and sustainable use of every drop of water, we are
continually dedicated to the service of society, state and nation keeping the
protection of flora and fauna in mind."

Feed mechanisms
Various feed mechanisms exist to feed material into a lathe at a
defined rate.
Bar feeder
A bar feeder feeds a single piece of bar stock into the cutting
machine. As each part is machined, the cutting tool creates a final
cut to separate the part from the bar stock, and the feeder continues
to feed the bar for the next part, allowing for continual operation of
the machine. There are two types of bar feeds used in lathe
machining: Hydrodynamic bar feeds, which rest the bar stock in a
series of channels whilst clamping down on the top and bottom of
the bar, and hydrostatic bar feeds, which hold the bar stock in a feed
tube using pressurized oil.
Bar loader
A bar loader is a variation on the bar feeder concept in that multiple
pieces of bar stock may be fed into a hopper, and the loader feeds
each piece as necessary.
30. PROCESS
Milling is a cutting process that uses a milling cutter to remove
material from the surface of a workpiece. The milling cutter is a
rotary cutting tool, often with multiple cutting points. As opposed
to drilling, where the tool is advanced along its rotation axis, the
cutter in milling is usually moved perpendicular to its axis so that
cutting occurs on the circumference of the cutter. As the milling
cutter enters the workpiece, the cutting edges (flutes or teeth) of the
tool repeatedly cut into and exit from the material, shaving off chips
(swarf) from the workpiece with each pass. The cutting action is
shear deformation; material is pushed off the workpiece in tiny
clumps that hang together to a greater or lesser extent (depending
on the material) to form chips. This makes metal cutting somewhat
different (in its mechanics) from slicing softer materials with a blade.
The milling process removes material by performing many separate,
small cuts. This is accomplished by using a cutter with many teeth,
spinning the cutter at high speed, or advancing the material through
the cutter slowly; most often it is some combination of these three
approaches.[2] The speeds and feeds used are varied to suit a
combination of variables. The speed at which the piece advances
through the cutter is called feed rate, or just feed; it is most often
measured in length of material per full revolution of the cutter.
31. There are two major classes of milling process:
In face milling, the cutting action occurs primarily at the end
corners of the milling cutter. Face milling is used to cut flat
surfaces (faces) into the workpiece, or to cut flat-bottomed
cavities.
In peripheral milling, the cutting action occurs primarily along
the circumference of the cutter, so that the cross section of the
milled surface ends up receiving the shape of the cutter. In this
case the blades of the cutter can be seen as scooping out
material from the work piece. Peripheral milling is well suited
to the cutting of deep slots, threads, and gear teeth.
