INTRODUCTION
Water Jet Machining (WJM) and Abrasive Water Jet Machining (AWJM) are two non-traditional or non-conventional machining processes.
They belong to mechanical group of non-conventional processes like Ultrasonic Machining (USM) and Abrasive Jet Machining (AJM).
In these processes (WJM and AJWM), the mechanical energy of water and abrasive phases are used to achieve material removal or machining
PARAMETERS AFFECTING CUTTING PERFORAMANCE OF THE AWJM
Waterjet nozzle diameter.
Supply pressure.
Abrasive parameters.
Abrasive material.
Stand off distance.
Impingement angle.
Depth of cut.
APPLICATIONS
Paint removal
Cleaning
Cutting soft materials
Cutting frozen meat
Textile, leather industry
Peening
Pocket milling
Drilling
turning
Endless Possibilities
Unmatched versatility
Expanded Capabilities
Reduction in material and Production Cost
Compliments Existing Technologies
Advantages
AWJM process maintains tight tolerances and produces parts quickly.
AWJM produces no heat affected zone.
Clean edges are produce.
Up to 40 plies can be cut.
Computer controlled.
Generates no dust.
Conclusion
The industry enjoys a reduction in replacement tooling costs, because more precision cutting is shifted to the water jet and less is being cut with the carbide cutting tools, the tooling experiences less wear.
Water jets are suitable for cutting high-strength materials into intricate shapes because relatively high cutting rates can be achieved.
The same water jet tool can be used on a variety of these materials simply by changing the cutting rate.
Thus this process can be widely used for fabrication of a large variety of components cost effectively and efficiently.
