Acknowledgement
I wish to express my sincere gratitude to all the faculty members of Department of
mechanical engineering whose allow me to give presentation on the Water jet cutter
system.
I acknowledge my gratitude to my family members for their unconditional support
and whole hearted blessing to accomplish this task.
A word of thank is due to my friends who stood by me and always helped me to take
the best foot forward and all the faculty and staff members of my collage. I
acknowledge all who helped us at each and every step where their support is required.
Lastly, I thank almighty God whose constant blessing has given us strength and
patience to bring this work into its present form.

Abstract
In the battle to reduce coasts, engineering and manufacturing departments are
constantly on the lookout for an edge. The water jet process many unique capabilities
and advantages that can prove very effective in the cost battle. Learning more about
the water jet technology will give us an opportunity to put these cost-cutting, the
water jet process is recognized as the most versatile and fastest growing process in the
world. Water jets are used in high production applications across the globe. They
complement other technologies such as milling, laser, EDM, plasma and routers. No
poisonous gases or liquids are used in water jet cutting, and water jets do not create
hazardous materials or vapors. No heat effected zones or mechanical stresses are left
on a water jet cut surface. It is truly a versatile, productive, cold cutting process. The
water jet has shown that it can do things that other technologies simply cannot. From
cutting whisper, thin details in stone glass and metals; to rapid whole drilling of
titanium; for cutting of food, to the killing of pathogens in beverages and dips, the
water jet has proven itself unique.
