Abrasive Jet Machine

Introduction
Abrasive jet machining (AJM) is a non-traditional machining
process that can machine material without generating heat and
shock.
Abrasive jet machining (AJM) is commonly used for Cutting,
Cleaning, Drilling and Etching operation

Mechanism of AJM

Fine particles are accelerated in
gas stream .

The particles are directed towards
the focus of machining.

As the particle impacts the surface,
it causes a small fractu ....etc

Water Jet cutting services make use of a super high pressure stream of water that carries an abrasive grit. This abrasive mixes with the water through a venturi effect in what is commonly called the ?focusing tube? just prior to cutting. This mixture of water and abrasive grit exit the focusing tube at speeds of approximately mach 2.5. Cutting pressures range between 45,000 to 60,000 psi for standard cutting models. For brittle, fragile, or delicate materials, piercing pressures range between 15,000 to 20,000 psi, and resume the higher cutting ....etc

seminar report on water jet machining

Abstract
Waterjet cutting, introduced in the early '70s, uses a highly pressurized stream of water, sometimes with an added abrasive. The waterjet stream, moving at nearly three times the speed of sound, can penetrate almost any material and thickness. Waterjets are often used on composites and plastics that cannot tolerate heat, mechanical damage, or delamination. And because the jet of water is constricted to a tiny diameter at such high pressures, the workpiece does not get wet.

WiFi Enabled Wireless Operated Fire Extinguisher Vehicle with Water Jet Spray

In this paper, the authors extinguish fire using robot which is remotely controlled through wireless. The robot can move through any path whose motion is controlled through the Wi-Fi network using buttons interfaced by a software program. When the robot faces a fire then it is made to extinguish the fire with the help of pump motor connected to a water tank mounted on its body. PC works as a remote to control the motion of the robot either to move it forward or bac ....etc
