Water jet cutting uses high-pressure water or water mixed with abrasive material to cut through materials. There are two types: pure water jet cutting uses only high-pressure water and can cut softer materials like wood, concrete, and glass. Abrasive water jet mixing uses garnet or olivine abrasives to cut harder materials like metals and composites. Water jet cutting has advantages like being able to cut any material, producing no heat-affected zones or sparks, and leaving smooth edges. However, it is not suitable for mass production due to high maintenance needs and inability to cut very thick materials.

• In this process, a water jet is used ,which act as a tool in the form of a
water saw to cut material.It is two types pure water jet & abrasive
water jet.

5. ABRASIVE WATER JET MACHINING :-
• Orifice-Sapphires-0.1 to 0.3 mm
• Focussing Tube- 0.8 to 2.4 mm
• Pressure -2500 to 4000 bar
• Abrasive Flow -0.1 to 1.0 kg/min
• Abrasive – garnet and olivine

6. FACTORS AFFECTING WJM PERFORMANCE

7. MATERIALS:-
ABRASIVE WATER JET
• Steels
• Non-Ferrous alloyes
• Ti-alloys,Ni-alloys
• Polymers
• Metal Matrix composite
• Ceramic matrix composite
PURE WATER JET
• Concrete
• Stone-Granite
• Wood
• Glass fibre metal
Laminates

8. ADVANTAGES:-
• Cheaper than other process.
• Cut any material
• Water jet cutting does not produce any dust or
particles.
• There is no heat affected zones.

9. DISADVANTAGES :-
• Abrasive powder cannot be reused.
• It is not suitable for mass production because
of high maintenance requirements.
• Very thick parts can not be cut with water jet.

10. APPLICATIONS
WATER JET MACHINING
• Cutting Soft Material
• Textile , Leather Industry
• Mass Immunization
• Surgery
ABRASIVE WATER JET
• Peening
• Cutting
• Pocket Milling
• Drilling
• Turning
• Nuclear Plant Dismantling

11. CONCLUSION:-
There is no conventional tool used, therefore no physical contact
between the workpiece and tool . This method is free from
generate high heat affected zones. It is moreover environmental
friendly, hence it is more preferred.
