Abrasive jet machining involves removing material from a workpiece using a high-velocity stream of abrasive particles carried by a gas. The process works by directing the abrasive particle jet through a nozzle at the workpiece surface. Material is removed through the erosive action of the abrasive particles striking the workpiece surface. Abrasive jet machining can cut hard and brittle materials and produces a high surface finish. It has advantages of low power consumption and capital cost but limitations include low material removal rates and high nozzle wear.
The mixture of abrasive particles with high pressurised air impinges through the nozzle towards the brittle material.Abrasive jet machining is done by use of abrasives(AL2O3,SIC,SYNTHETIC DIAMOND,ETC.,) particles. The main components are nozzle,mixing chamber,dehumidifier,regulator and pressure gauge.
Advance machining processes are used where higher accuracy and surface finish is required. One of them, Abrasive jet machining is a non-traditional machining process in which a high-pressure air stream and abrasive particles impinge on a work surface through a nozzle. Abrasive jet machining (AJM) removes material through the action of a focused beam of abrasive jet directed at the workpiece the resulting erosion can be used for cutting, drilling and debarring etc. With the increase of needs for machining of ceramics, semiconductors, electronic devices and L.C.D., AJM has become a useful technique for micromachining. it is more useful in industries for precision work. Material removal rate during this process affected by different parameters like abrasive particle size, the velocity of abrasive flow rate, gas pressure, standoff distance etc.

A Review on Multi-objective Optimization of Process Parameter of Abrasive Wat...IJARIIT
Glass fiber reinforced polymer (GFRP) composites are increasingly being used in a large number of applications in product manufacturing because of the superior advantages they offer compared to other traditional and non-traditional materials such as high strength to weight ratio, high modulus, high fracture toughness, and corrosion and thermal resistance, low cost of production, light weight, inherent strength, weather-resistant finish and variety of surface textures. However conventional machining of Glass fiber reinforced polymer (GFRP) is not so economical and ease, on the other hand non-conventional processes like laser cutting, abrasive water jet machining (AWJM), and electric discharge machining (EDM) etc., have a very good potential in overcoming these machining difficulties. Among these AWJM is commonly employed for very hard and brittle materials due to its Economical and Technical significance.
Abrasive water jet machining (AWJM) is a relatively new machining technique. Abrasive Water Jet Machining is extensively used in many industrial applic ations.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

• Component of AJM
• Working Parameter of AJM
• Advantages
• Disadvantages
• Conclusion
3. INTRODUCTION OF AJM
Abrasive jet machining (AJM) is a process
in which the material is removed from the work piece
due to impingement of fine grain abrasive by a high
velocity gas stream.
The stream of abrasive mixed gas is directed
to the work piece by suitably designed nozzle.
This process differs from the conventional sand
blasting in that the abrasive used is finer and the
process parameters and cutting action is carefully
controlled.
7. WORKING OF AJM
Abrasive jet machining is a process in which
material removal takes place due to erosive action
of a stream of fine-grained abrasive particles
impacting at high velocity on the work surface.
Fine-grained abrasive particles mixed in
suitable portion with high pressure carrier gas,
usually air, are directed through a suitably designed
nozzle.
The nozzle used imparts high velocity to the
carrier gas and thereby to the jet of abrasive
particles at the nozzle exit. This is directed onto the
work surface to be machined
8. WORKING OF AJM
The erosion of a surface by solid particles
entrained in a fluid stream has received consideration
attention from many investigators in the past.
The theory of erosion phenomena in such
situation is not fully understood and adequate data of
its governing parameters are not available; some of
these parameters are interdependent and difficult to
control.
The first phase involves the determination from
fluid condition, of the number, direction and velocity
of abrasive particles striking the work surface.
9. WORKING OF AJM
The first phase is essentially a two-phase (solid-
gas suspension) flow problem and is beyond the
scope of present work. The discussion will, therefore,
be confined to mechanism of material removal or
erosion rate.
The erosion of materials by surface impact of
hard particles is a complex phenomenon, consisting
of several simultaneous and interacting, typically
involving mechanical, chemical and material
parameters as well as complex mechanism
10. WORKING PARAMETERS IN AJM
• Carrier gas.
• Types of abrasives.
• Size of abrasive grains.
• Velocity of abrasive jet.
• Mean number of abrasive particles per writ volume of
carrier gas.
• Work material.
• Stand of distance
• Nozzle design.
• Shape of cut.
12. ADVANTAGES
There is no mechanical contact between the tool and
work piece.
It can cut hole of intricate shapes in hard and brittle
materials.
Surface finish obtained is high.
Depth of surface damage is low.
Power consumption is low.
Capital cost is low.
Accuracy up to 0.05 mm can be obtained.
13. LIMITATION
Metal removal rate is low.
Nozzle wear is high.
In machining soft metals, abrasive get embedded into
the metals as a result an additional cleaning operation
is required.
Stray cutting and tapering are unavoidable, thus,
machining accuracy is poor.
Process tends to pollute the environment, so, dust
collecting system is required.
14. APPLICATION
For cleaning of the spark plug and casting.
Removal of flash mid parting lines from the injection
moulded parts.
It’s widest used is in cutting, drilling, deburring and
cleaning of hard and brittle materials.
The process is also used to machine thin section and
intricate shapes in hard and brittle materials.
Deburring and cleaning of Plastic, Teflon, Nylon
components is another application of this process.
It is used in producing high quality surfaces
Production of high quality surface.
15. CONCLUSION
Abrasive jet machining can be used for
polishing, debarring and other finishing operation
where the rate of material removal is important,
while in operation such as micro-drilling and cutting
it is the erosion depth which is more relevant
