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.

Stainlesssteel 403 is high-alloysteelwith good corrosion resistance and it’svery hard material. Abrasive water jet
is an effective method for machining, cutting and drilling of stainlesssteel 403. In thispaperweoptimize the
metalremoval rate of stainlesssteel 403 in abrasive water jet machining. The MRRisoptimize by

Taguchimethod use to analyse the result. 9 experimentalrunsbased on L9 orthogonal array of Taguchimethod.
The development of high performance material such as composites and advanced ceramics has a variety of
manufacturing challenges. It is known that many of these materials cannot be effectively machined by conventional machining methods. Apart from economics, the process selection is based on the machined surface integrity. The high pressure waterjet with abrasive additives known as abrasive water jet (AWJ) is one viable alternative to conventional processing and has been suggested for use in post mold shaping of composites and other hard to cut material. The research works on water jet cutting is discussed in this paper. Omni directional cutting potential as well as minimal thermal and mechanical loading are few
advantages. There are several parameters influencing the performance of abrasive water jet machining. Important process parameters which mainly affect the quality of cutting are traverse speed, hydraulic pressure, abrasive flow rate, standoff distance, and abrasive type, work material. Material removal rate(MRR) and surface roughness (Ra), taper of cut, width of cut are important quality parameters of AWJM.
Abrasive water jet review and parameter selection by AHP method.IOSR Journals
An Abrasive Water Jet is one of the most recently developed non-traditional manufacturing
processes. Abrasive water jet offers the potential for the development in cutting which is less sensitive to
material properties, has virtually no thermal effects, and imposes minimal stresses. As it is a cold process has
also important applications where heat-affected zones are to be avoided. In this work, a deep study of this newer
non-conventional technique of machining i.e., abrasive water jet machining is done. In this paper more focus is
on selection of various process parameters like-angle of impact, Pressure inside the pumping system, abrasive
material type, Stand-off distance, focusing tube diameter, nozzle speed, abrasive mass flow rate and target
material properties for getting the required output like- depth of cut and cut quality. For cutting Stainless steel
(Grade 304), important task is to find out a few parameters which influence more. With the help of Analytical
Hierarchy Process technique the selection of a few parameters are done which are comparatively more
influencing. Weighteges are given to parameters on the basis of previous study and experience of owner of the
company who is dealing with abrasive water jet technology since many years.

The present work attempts to investigate the effect of operating pressure on depth of penetration and kerf characteristics generated while machining of D2 heat treated steel. It is found that increase in operating pressure increases the depth of penetration and decreases the surface taper on the work-piece. Keywords: Kerf width, Depth of cut, Operating pressure, AWJ Machining
Investigation of Metal Removal Rate and Surface Finish on Inconel 718 by Abra...AM Publications
Abrasive Waterjet (AWJ) cutting has proven to be an effective technology for material processing with the distinct advantages of no thermal distortion, high machining versatility, high flexibility and small cutting forces. In this paper, Taguchi robust design analysis is employed to determine optimal combination of process parameters. The Analysis of Variance (ANOVA) is also applied to identify the most significant factor. The process parameters such as pressure, transverse speed, stand of distance and abrasive flow rate are optimized to investigate their influence on Metal Removal Rate (MRR) and Surface Roughness (Ra) of Inconel. Experiments are carried out by L9 orthogonal array and the results are provided to verify this approach and credible tendencies of output parameters with respect to the input parameters are discussed, from which recommendations are made for process control and optimization.

Surface Quality Improvement Using Modified Tool Clamping In Boring OperationsIJRES Journal
Boring operations are challenging owing to limited process performance due to inherent tool overhang and resulting vibrations. The tool vibrations can be suppressed with insertion of suitable damping methodology. The present work adopts a method suitable for machine operators, where in insertion of packing sheets at the boring tool support has been suggested. Insertion of number of layers causes frictional phenomenon to dissipate the exciting energy thereby damping the vibrations. Substantial improvement of surface quality of the internally machined surfaces has been noticed in the experiments

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

removal of material takes place by impact
erosion of high pressure, high velocity of water
and entrained high velocity of grit abrasives on a
work piece. The objective of experimental
investigation is to conduct research of machining
parameters impact on Material removal rate and
Surface roughness of work piece of Mild Steel
(MS). The approach was based on Taguchi’s
method, analysis of variance and signal to noise
ratio (SN Ratio) to optimize the Abrasive Water
Jet Machining process parameters for effective
machining and to predict the optimal choice for
each AWJM parameter such as Traverse speed,
Abrasive flow rate, and Standoff distance. There
is L9 orthogonal array used by varying
Transverse Seed, Abrasive flow rate, standoff
distance respectively and for each combination
we have conducted three experiments and with
the help of Signal to Noise ratio we find out the
optimum results for AWJM. It was confirmed
that determined optimal combination of AWJM
process parameters satisfy the real need for
machining of Mild Steel (MS) in actual practice.

1. INTRODUCTION
Abrasive Water Jet Machining is accepted
effective technology for cutting various material as
of its advantages over other non-conventional
techniques such as No heat is generated in the
cutting process, high machining versatility,
minimum stresses on the work piece, high flexibility
and small cutting forces, the abrasives after cutting
can be reused which allows for possible reduction of
the cutting cost of the process, machining can be
easily automated. The process has some limitations
and drawbacks. It may generate loud noise and a
messy working Environment, the machining is not
applicable for machining too thick pieces, limited
number of materials can be cut economically, taper
cutting is also a problem with water jet cutting in
very thick materials.
As in the case of every machining process, the
quality of AWJC process is significantly affected by
the process tuning parameters. There are numerous
associated parameters in this technique, among
which water pressure, abrasive flow rate, jet traverse
rate, standoff distance and diameter of focusing
nozzle are of great importance but precisely
controllable . The main process quality measures
include attainable depth of cut, material removal
rate and surface finish. Number of techniques for
improving kerf quality and surface finish has been
proposed.
2. WORKING PRINCIPLE
Abrasive water jet cutting is using high
pressure water being forced through a small hole
onto a concentrated area to cut materials. The
Abrasive water jet cutting machine starts with a
water pump. The water pump pressurizes the water
and pumps it from a water tank or other water
supply to the nozzle.
Fig.1: Abrasive Water Jet Machining
If there is an abrasive added it is normally
added at the nozzle which has shown in Below
Figure. A lot of water is forced through a small
nozzle. This creates water with a lot of pressure.
This pressure makes the particles “accelerate” and
hits a very small area on the piece being cut.
All of the pressure onto the material being
cut makes the material crack. It creates very small
cracks and the pressure washes away the particles of
material. The pressure eventually removes all of the
material in the small area and this is the cut. The
material being cut is in a catch tank that is full of

water and other debris. The water is normally raised
to just above the material to reduce the splash that
may occur during cutting. All of the material that is
being removed goes into the catch tank and can later
be removed.
2.1 ABRASIVE WATER JET CUTTING
MACHINE ELEMENT:
Abrasive water jet cutting machines have
four basic elements: pumping system, abrasive
feed system, abrasive water jet nozzle and
catcher.
The pumping system produces a high-velocity
water jet by pressurizing water up to as high as
400 Mpa using a high-power motor. The water
flow rate can be as high as 3 gallons per minute.
To mix the abrasives into this high-velocity
water jet, the abrasive feed system supplies a
controlled quantity of abrasives through a port.
The abrasive water jet nozzle mixes abrasives
and water (in mixing tube) and forms a high
velocity water abrasive jet. Sapphire, tungsten
carbide, or boron carbide can be used as the
nozzle material. There are various kinds of
water abrasive jet nozzles.
Another element of the system is a catcher, for
which two configurations are commonly
known: a long narrow tube placed under the
cutting point to capture the used jet with the
help of obstructions placed alternately in the
opposite direction and a deep water-filled
settling tank placed directly underneath the
work piece in which the abrasive water jet dies
out.
3. EXPERIMENTAL WORK
(A) Material:
Mild steel is the most common form of steel
because its price is relatively low while it
provides material properties that are acceptable
for many applications. It is often used when
large quantities of steel are needed, for example
as structural steel. It is the most versatile form
of steel. Mild steel – Grade 250 plates were
used as the specimens in this study.
(B) Equipment:
The equipment used for machining the samples
was Water Jet Model: DWJ1525-FA which was
equipped with SL-V50 pressure pump with the
designed pressure of 290 Mpa . The machine is
equipped with a gravity feed type of abrasive
hopper, an abrasive feeder system, a
pneumatically controlled valve and a work
piece table with dimension of 3000 mm x 3000
mm. Sapphire orifice was used to transform the
high-pressure water into a collimated jet, with a
carbide nozzle to form an abrasive waterjet. set

3.1 Design of Experiment (DOE)
Design of experiments (DOE) is a powerful
tool that can be used in a variety of experimental
situations. DOE techniques enable designers to
determine simultaneously the individual and
interactive effects of many factors that could affect
the output results in any design. To achieve a
thorough cut it was required that the combinations
of the process variables give the jet enough energy
to penetrate through the specimens.
Most researchers identified Abrasive water
jet machining process parameters that greatly affect
Response parameter. The Process Parameter like
Standoff distance, impact angle, traverse rate,
number of passes, abrasive material, abrasive
particle size, abrasive shape, and abrasive mass flow
rate, focusing tube diameter and focusing tube
length water pressure orifice diameter etc. In this
paper we have selected process parameter as
Traverse rate (mm/min), Abrasive flow rate
(gm/min) and Stand of distance (mm) to analyze its
effect onr MRR (gm/min) and Surface Roughness
(𝛍m) in AWJM.

4. RESULT AND DISCUSSIONS
Surface roughness is one of the most
important criteria, which help us determine how
rough a workpiece material is machined. In all the
investigations it was found that the machined
surface is smoother near the jet entrance and
gradually becomes rougher towards the jet exit. This
is due to the fact that as the particles moves down
they loose their kinetic energy and their cutting
ability deteriorates. By analyzing the experimental
data of the selected material, it has been found that
the optimum selection of the four basic parameters,
i.e., water pressure, abrasive mass flow rate, nozzle
traverse speed and nozzle standoff distance are very
important on controlling the process outputs such as
surface

roughness. The effect of each of these parameters is
studied while keeping the other parameters
considered in this study as constant
4.1 ANOVA ANALYSIS
4.1.1 Main effect plot of MRR
Fig.3:- Main Effect plot for SN Ratio (MRR) v/s
Factors
Above plot shows the main effect plot of MRR at
different parameters like Traverse speed, Abrasive
flow rate and Stand of distance in Abrasive water jet
machining process of MS
Main effects of MRR of each factor for various level
conditions are shown in above figure. According to
above figure the MRR increases with three major
parameter TS, AFR, and SOD. MRR is maximum in
the case of Traverse Speed (TS) at level 1 (350), in
the case of Abrasive flow Rate (MFR) at level 1
(350), and in the case of Standoff distance (SOD)
MRR will be maximum at level 1 (10). So the
optimal parameter setting for the MRR found TS
(350) MFR (350) SOD (10).

Above plot shows the main effect plot of
Surface Roughness at different parameters like
Traverse speed, Abrasive flow rate and Stand of
distance in Abrasive water jet machining process of
MS.
Above plot evaluates the main effects of each factor
for various level conditions. According to the above
figure the surface Roughness decreases with three
major parameter TS, AFR, and SOD. SR will be
minimum in the case of Traverse Speed (TS) at
level 1 (250), in the case of Abrasivw flow Rate
(AFR) at level 1 (250), and in the case of Standoff
distance (SOD) at level 2(6). So the optimal
parameter setting for minimum surface roughness is
TS (250) MFR (250) SOD (6).
4.2 OPTIMUM CONTROL PARAMETER LEVEL
The ANOVA for desired response provide
the significant factor. Therefore the optimal level of
a significant control factor is the level with the
greatest SN Ratio. Optimizing the output parameter
is achieved by selecting the significant control factor
at their optimum level. Control factor that are not
significant can be set at any level.

5. CONCLUSION
In this presents analysis of various
parameters and on the basis of experimental results,
analysis of variance (ANOVA), and SN Ratio the
following conclusions can be drawn for effective
machining of MILD STEEL (MS) by AWJM
process as follows:
Traverse Speed (TS) is the most significant
factor on MRR during AWJM. Meanwhile
Abrasive Flow Rate and Standoff distance are
sub significant in influencing. The
recommended parametric combination for
optimum material removal rate is TS (350)
MFR (350) SOD (10).
In case of surface Roughness Abrasive Flow
Rate is most significant control factor and
hence the optimum recommended parametric
combination for optimum surface Roughness is
TS (250) MFR (250) SOD (6) .
