Waterjet-Cutting-Head:-
Multiaxis machining is a manufacturing
process, where computer numerically
controlled tools that move in 4 or more
ways are used to manufacture parts out
of metal or other materials by milling
away excess material, by water jet cutting
or by laser cutting. Typical CNC tools
support translation in 3 axes; multiaxis
machines also support rotation around
one or multiple axes.
There are now many CAM (computer
aided manufacturing) software systems
available to support multiaxis machining
including software that can automatically
convert 3-axes toolpaths into 5-axes
toolpaths.

SCREW JACK-
Screw jack systems are used in
automatized production plants worldwide.
screw jack systems are not only for the
simple stock lifting from a few kilograms to
100 tonnes, but also responsible for
movements in all directions. Excavators
work with hydraulics, light weights can be
moved fast pneumatically - screw jack
technology comes into play, where loads
need to be controlled and positioned
precisely.
Designers and engineers find ideas and
solutions for lifting loads from 0.25 kN to
1000 kN with our modular system.
There are numerous applications, for
example, theatre and stage construction,
plants for the production of sheet steel
and steel pipes, wood working machines,
plastics processing machines, textile
machines, assembly equipment in the
automobile and aircraft industries, food
and beverage production equipment as
well as packaging machines.

Gas compressor
Interest
A gas compressor is a mechanical device
that increases the pressure of a gas by
reducing its volume.
Compressors are similar to pumps: both
increase the pressure on a fluid and both
can transport the fluid through a pipe. As
gases are compressible, the compressor
also reduces the volume of a gas. Liquids
are relatively.

5 Operations of Lathe Machine:
(i) Facing: This operation is almost
essential for all works. In this operation,
as shown in fig., the work piece is held in
the chuck and the facing tool is fed from
the center of the work piece towards the
outer surface or from the outer surface
to the center, with the help of a cross-
slide.
(ii) Plane Turning: It is an operation of
removing excess amount of material from
the surface the surface of the cylinder
work piece. In this operation, shown in
fig., the work is held either in the chuck
or between centers & the longitudinal
feed is given to the tool either by hand or
power.
(iii) Step Turning: It is an operation of
producing various steps of different
diameters of in the work piece as shown
in fig. This operation is carried out in the
similar way as plain turning.
(iv) Drilling : It is an operation of making
a hole in a work piece with the help of a
drill. In this case as shown in fig., the
work piece, by rotating the tail stock
hand wheel. The drill is fed normally, into
the rotating work piece, by rotating the
tail stock hand wheel.
(v) Reaming : It is an operation of
finishing the previously drilled hole. In the
operation as shown in fig., a reamer is
held in the tailstock and it is fed into the
hole in the similar way as for drilling.

ABS - Anti-lock Braking System:
It is an automobile safety system that
allows the wheels on a motor vehicle to
maintain tractive contact with the road
surface according to driver inputs while
braking preventing the wheels from locking
up (ceasing rotation) and avoiding
uncontrolled skidding. It is an automated
system that uses the principles of threshold
braking and cadence braking which were
practiced by skilful drivers with previous
generation braking systems. It does this at
a much faster rate and with better control
than a driver could manage.
ABS generally offers improved vehicle
control and decreases stopping distances
on dry and slippery surfaces for many
drivers; however, on loose surfaces like
gravel or snow-covered pavement, ABS
can significantly increase braking distance,
although still improving vehicle control.
There are four main components to an ABS
system:
1 Speed sensors
2 Valves
3 Pump
4 Controller
Speed Sensors:
The anti-lock braking system needs some
way of knowing when a wheel is about to
lock up. The speed sensors, which are
located at each wheel, or in some cases in
the differential, provide this information.
Valves:
There is a valve in the brake line of each
brake controlled by the ABS. On some
systems, the valve has three positions:
In position one, the valve is open; pressure
from the master cylinder is passed right
through to the brake.
In position two, the valve blocks the line,
isolating that brake from the master
cylinder. This prevents the pressure from
rising further should the driver push the
brake pedal harder.
In position three, the valve releases some
of the pressure from the brake.
Pump:
Since the valve is able to release pressure
from the brakes, there has to be some way
to put that pressure back. That is what the
pump does; when a valve reduces the
pressure in a line, the pump is there to get
the pressure back up.
Controller:
The controller is a computer in the car. It
watches the speed sensors and controls
the valves.
ABS at Work:
There are many different variations and
control algorithms for ABS systems. We will
discuss how one of the simpler systems
works.
The controller monitors the speed sensors
at all times. It is looking for decelerations
in the wheel that are out of the ordinary.
Right before a wheel locks up, it will
experience a rapid deceleration. If left
unchecked, the wheel would stop much
more quickly than any car could. It might
take a car five seconds to stop from 60
mph (96.6 kph) under ideal conditions,
but a wheel that locks up could stop
spinning in less than a second.
The ABS controller knows that such a rapid
deceleration is impossible, so it reduces the
pressure to that brake until it sees an
acceleration, then it increases the pressure
until it sees the deceleration again. It can
do this very quickly, before the tire can
actually significantly change speed. The
result is that the tire slows down at the
same rate as the car, with the brakes
keeping the tires very near the point at
which they will start to lock up. This gives
the system maximum braking power.
When the ABS system is in operation you
will feel a pulsing in the brake pedal; this
comes from the rapid opening and closing
of the valves. Some ABS systems can cycle
up to 15 times per second.

A conveyor belt (or belt conveyor) consists
of two or more pulleys, with a continuous
loop of material - the conveyor belt - that
rotates about them. One or both of the
pulleys are powered, moving the belt and
the material on the belt forward. The
powered pulley is called the drive pulley
while the unpowered pulley is called the
idler. There are two main industrial classes
of belt conveyors; Those in general
material handling such as those moving
boxes along inside a factory and bulk
material handling such as those used to
transport industrial and agricultural
materials, such as grain, coal, ores, etc.
generally in outdoor locations. Generally
companies providing general material
handling type belt conveyors do not
provide the conveyors for bulk material
handling. In addition there are a number of
commercial applications of belt conveyors
such as those in grocery stores.
The belt consists of one or more layers of
material. They can be made out of rubber.
Many belts in general material handling
have two layers. An under layer of material
to provide linear strength and shape called
a carcass and an over layer called the
cover. The carcass is often a woven fabric
having a warp & weft. The most common
carcass materials are polyester, nylon and
cotton. The cover is often various rubber
or plastic compounds specified by use of
the belt. Covers can be made from more
exotic materials for unusual applications
such as silicone for heat or gum rubber
when traction is essential.
