�Operating principal :
� Depends upon nozzle orifice diameter, water
pressure and cutting feed rate.
� Stand distance affect the performance.
� Mechanism is performed by:
�
� Conditions:-
1. pump along with intensifier to generate very highpressure.
2. cutting unit consisting nozzle and workable unit.

WATER JET Here are some of the benefits to using a water jet:
� Cheaper than other processes.� Cut virtually any material:
1. pre hardened steel
2. mild steel
3. Copper, Brass, Aluminum: They are a cinch!
4. brittle materials like glass, ceramic, quartz, stone.
� Cut thin stuff, or thick stuff
� Make all sorts of shapes with only one tool.
� Cut wide range of thickness¶ to reasonable tolerance up to 2´ (50mm)thick
� Up to 5´ (127mm) or thicker where tolerance not important, or in soft
materials.
� No Heat Generated / No heat affected zones - this is cold cutting!

WATER JET CO N CLUSIO N :-
�From above discussion we have concluded that ³Water jet Machining´
is:
�Cheaper than other process.
�Cut virtually any shape &material
�Make all sorts of shapes with only one tool.
�Cut wide range of thickness¶ to reasonable tolerance up to 2´ thick
�No mechanical stresses
�Fast turn around on the machine.
�Leaves a satin smooth finish, thus reducing secondary operations
�Clean cutting process without gasses or oils
