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.

Micromachining
Implies parts are made to the size of 1 to 999 m
By the definition micro engg: as the field where component sizes are a few millimeters
Important aspects
Unit removal
Equipment precision
Classification According to Machining phenomena
Removal by mechanical force
Removal by ablation
Removal by dissolution
Plastic deformation
Laser micro machining
Uses a power source (FS laser, Excimer laser) that emits a beam with very high quantum energy.
Laser M ....etc

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
