Artificial Neural Network and Adaptive neuro fuzzy
inference systems.
The main objective of this paper is to
determine casting defects generally happening in an
aluminium die casting process and efforts have been
taken to identify the tools which eliminate the casting
defects. In global prospective this study briefs the
application of the various tools that are used in the
industries for improvement of quality in foundry
industry. In our national prospective these tools are not
so popular, hence this study will help us to utilise the
available technology through which the productivity is
enhanced with safe and economical means. The QC
tools were used to analyse the casting condition of the
given pattern with three dimensional simulations for the
result preparation. This work has been carried out to
improve the quality of the pattern which is made with
gravity die casting process and this was achieved
through continuous quality control operation with QC
tools, then it was taken to test in some simulation
software. The latest trend available in casting and
foundry shops are the scientific approach in
optimization of all kind of fields including optimization
of defects in castings. These trends are incorporated in
the analysis of aluminium die casting.
Friction Stir Welding, a type of welding which was
discovered in the year of 1991 with a few countable methods
and processes. But today it is one of the necessary and
important type of welding techniques. To develop it, several
researchers showed their interests in this technique. Today,
it acts as the heart of welding of automobiles. Thousands of
inventions has been made in field of Friction Stir Welding
and also successfully being implemented. If a researcher
tries to make some research in this field, he has to go
through thousands of journals where hours of time is being
consumed. To solve that problem several Re-view journals
are being published and also successfully solved this issue
of time consumption. In this paper, similarly a re-view of
several important and different types of papers are discussed
with their results, outcomes, the parameters being performed
for analysis.
This paper also discusses about various methods and various
metals as tools and job materials. It will be much easier and
lenient to understand from this paper to research. The
authors of the papers also clearly explained about the usages
and applications of their methods and provided several
statistical data for clear observation of their methods
The present research work demonstrates the
preparation of Copper Oxide Nanoparticles (CuO NPs) and
investigates the thermo mechanical properties of the CuO NPs
embedded in the polymer composites experimentally. In this study,
CuO NPs were produced by aqueous precipitation method and
morphology of the NPs was studied using Field Emission
Transmission Electron Microscope (FESEM). Epoxy resin and glass microsphere were considered the base material for the preparation of
the Nano based polymer composites. In order to fabricate the Nano
based polymer composites, CuO NPs with 1.0wtpercentage were
embedded in the base material by means of compression moulding
press. Nano composites proved higher thermal conductivity
enhancement rather than the base material. While comparing to the
base material, the maximum four-point bending strength of 415 MPa
was obtained from the Nano based polymer composites. The test
results obtained from the TG study revealed that an addition of CuO
NPs had acted as the thermal retardant and CuO NPs had delayed
thermal degradation of the Nano based polymer composites. Based
on the test results, it can be suggested that the newly fabricated
nanocomposites have achieved the improved thermal and mechanical
properties.

The dynamic stability of machine has its own importance in the quality of the machined product. With the development of new technologies for cutting tools, as the geometries and materials, cutting speeds used today reach values inconceivable for two decades. In the automotive industry steel and cast iron are gradually being replaced by lower density material and even lower costs. In complex shapes tools, heterogeneous material removal in roughing, sudden changes of sections, etc. Stress relieving treatment should be carried out to minimize dimensional variations of form during quenching and tempering. Materials for manufacture of thermal fixing most appropriate for that operating system still needs to be further investigated. Therefore, this study investigated the elastic behavior of the material used in the manufacture of tooling systems for cutting tools. Has been evaluated In fastening system, the temperature variation exerted on the mandrel body region and the thermal expansion where H13 steel can withstand the assembly process by thermal interference.

A REVIEW ON OPTIMIZATION OF RESISTANCE SPOT WELDING OF ALUMINUM COMPONENTS US...AM Publications
Resistance Spot welding (RSW) is one of the common welding processes used for sheet joining especially in the automobile and aerospace industry. It is used in a wide range of industries but notably for the assembly of sheet steel vehicle bodies. This is a type of resistance welding where the spot welds are made at regular intervals on overlapping sheets of metal. Spot welding is primarily used for joining parts that are normally up to 3 mm in thickness. The joint quality can be defined in terms of properties such as weld-bead geometry, mechanical properties and distortion.The objective of the research is to determine the optimum combination of parameters responsible for better quality of joints. The complicated behavior of the process must be analyzed to set the optimum parameters to get the optimum weld quality. The paper also presents the FEA simulation of the RSW process.

This work is a contribution to the study of the rigidity of rotational friction welding of cylindrical specimens made on a parallel lathe. We performed welding of three combinations of parts: steel / steel, aluminium / aluminium and steel / aluminium according to three numbers of rotations of the spindle (900, 1250 and 1800 rpm). To control the rigidity and quality of these assemblies, tensile tests are used followed by ultrasonic testing to ensure that the tips are welded and that there are no internal defects. Hardness profile of the welded zone according to the welding parameters was obtained. Metallographic observations have detected the profile of the various zones welded and affected thermally. The results of the mechanical tests showed that a rotation speed of 1250 rpm can produce a very good weld, with other parameters kept constant.
Problems of Heat, Mass and Momentum Transfer in Manufacturing Processes: A Br...drboon
In machining processes the chip flows over the tool rake and carries heat away as it moves. This is a case of mass transportation with heat transfer. Similarly, during hot forging, upsetting or coining processes heat is transferred from the hot billet to the relatively cooler dies, punches or hammers with momentum transfer under high impact load. Also, in high energy rate fabrication (HERF) processes, such as electromagnetic forming, explosive forming, impact extrusion, etc. heat is generated almost instantaneously, in milliseconds, and its dissipation is a serious industrial problem due to the very short process cycle time. In the present paper some of the problems related to heat, mass and momentum transfer in the above mentioned manufacturing processes are reviewed and compared with experimental results.

In the present paper an optimization of process parameters of a cold chamber aluminium die casting operation is
discussed. The quality problem encountered during the manufacturing of a die casted component was porosity and the
various potential factors causing it are identified through a thorough cause-effect analysis. The Ishikawa diagram (cause
and effect diagram) was constructed to identify the casting process parameters that may affect the porosity. An analysis of
variance (ANOVA) is further conducted to find the factors having significant effects on porosity. The pressure of the
plunger used in the die casting machine and the temperature of the liquid aluminium are identified as significant factors
after the ANOVA test. Then a back propagation ANN is modelled and trained with the above two process parameters and porosity in order to predict or control the output by optimizing the input process parameters.

Optimization of Cutting Rate for EN 1010 Low Alloy Steel on WEDM Using Respon...IJAEMSJORNAL
EN 1010is a low-carbon steel alloy with 0.10% carbon content. It is known for its fairly low strength and low ductility; however, it can be tempered to increase strength. Machinability of EN 1010 carbon steel is measured to be fairly good. EN 1010 is commonly used for cold headed fasteners, rivets and bolts, in addition to structural, construction and automotive applications such as fenders, pans, nails and transmission covers. Wire Electric Discharge Machine (WEDM) seems to be a good option for machining the complicated profiles. This paper, find effects of various process parameters of Wire EDM such as pulse on time (Ton), pulse off time(Toff), peak current (Ip) and servo voltage (Sv) for analysis of cutting rate (CR) while machining EN 1010. Central Composite Design is used to plan the design of experiment. The output response variable being cutting rate will be measured for all number of experiments conducted. The optimal parameter level combination would be analysed which gives desired cutting rate. These optimized values of different parameters would then be used in execution the machining operation in order to obtain the necessary outputs.
SIMULATION OF THE DRILLING PROCESS IN GFRP COMPOSITES USING SYSTEM DYNAMICS A...IAEME Publication
This paper intends to present the System Dynamics (SD) as a novel method to
simulate the thrust force developed during drilling of GFRP composites. Good quality
holes are extremely fundamental so as to accomplish equally good joints amid
creation of components prepared from composite for better execution. Since the
nature of a drilled hole is subject to material properties and machining conditions, it
is important to think about the impacts of these factors on the nature of hole obtained.
In the present work, the machining parameters thickness of the material, drill point
angle, drill size, drill speed and feed rate are selected to evaluate their effect on the
quality of the hole. Past works uncover the fact that the damage caused to the drilled
hole is primarily due to the thrust force. Consequently it is fundamental to limit the
thrust force so as to accomplish better quality of the drilled hole. The SD simulation
model was implemented through a causal loop diagram. A mathematical equation
used in the simulation was developed utilizing the Design of Experiments (DOE)
technique. VENSIM programming was utilized to create and run the SD model. The
SD simulation results were compared with Artificial Neural Networks (ANN) results,
Response Surface Methodoly (RSM) results and the experimental results. A decent
agreement was seen between SD, ANN and RSM results

The objective of this paper is to use the
Android mobile application to purchase grocery
items. This would help the consumers to purchase the
grocery items through their mobile application and
get the grocery items delivered to their home, office
or anywhere else directly. The users can also select
the nearby provision store or any other supermarket
which is present in their location and then select their
items. The application is thoroughly built only in the
Android platform and is supported only for Android
mobiles. Thus, the application guarantee about userfriendly
in use, provides help desk, security services
etc. This would save the time of the purchaser instead
of going to the grocery store to snap up the items and
standing on a big queue for debiting the products
andwould also help the shop proprietor to develop
their business which will not depreciate their business
revenue for adapting this system by the consumers. It
also helps retailers to create brand awareness so that
the consumers feel self-assured to themselves about
the products procure through online. This would lead
the consumers to increase their familiarity in
purchasing grocery products through an online
application using the internet. The shopkeepers
should also ensure timely delivery of ordered grocery
products without any imperfection in the products
and also ensuring the damage to the products at the
time of deliverance.
Our future battle field system will have more difficulties to maintain security, because of increasing military competitive. Ability to understand, predict and adopt the vast array of inter-networked things is very difficult. Unwanted fire, unauthorized human intervention and other object movement will play major important role for affecting military environment.

These days heart diseases are
considered as the major health issue. It
includes heart attack and cardiac arrest.
Heart attack is the global leading cause
of death for both the genders and
occurrence is not always know.
Sometimes heart attack is often
compared with other type of pain and
not often dealt with it. Hence, this
project is to implement the heart rate
monitoring using IOT. The patients are
expected to carry or wear a hardware
sensor. The sensor with note the heart
rate and transmits it through internet.
The patient may be expected to set the
high and low heart rate individually. On
reaching the high rate or going below
the expected heart rate, an emergency
alert notification is sent to the patient’s,
guardian, doctor and
ambulance(optional) android devices.
Wildlife entering in to populated areas has
recently become very Popular. The space for wild
animals is decreasing as humans are encroaching
forests. It creates great loss to property and life
when wild animals enter in to cities. We use latest
advances in technology such as Internet of Things
(IoT) to create an alert system of possible wildlife
leaving the forest and also the message will send to
the users Mobile to alert them. We use low cost
motion detectors and Passive Infrared sensors to
achieve this. We relay information of such motion
to a control centre to take further actions. We also
include making loud noise through speakers in
which the animals cannot enter in to land. The
basic idea of IoT is to connect different sensors
and establish communication and also provide
services. In this article, we make use of several IoT
devices at the periphery of natural reserve to
create an alert system. This system can also be
used to find out smugglers and other people
illegally entering in to the forest.
—In a laboratory experiment was conducted on
the utilization of Ethanol-Diesel emulsion in a single
cylinder direct injection diesel engine, a single cylinder,
water cooled, four stroke diesel engine was used. The
principal goals of the present work are to obtain emission
data and combustion characteristics for this type of Diesel
Engine, and to identify the ratio of Emulsion which is
effective in reducing emissions. Experiments were
conducted with emulsions viz (90%diesel + 10%ethanol),
(80% diesel + 20% ethanol), (70% diesel + 30%ethanol) as
fuel. While AVL smoke meter was employed to measure
the smoke density in HSU, the exhaust gas analyzer was
used to measure the NOx emission. High volume sampler
was employed to measure the particulate matter emitted at
the exhaust. The combustion characteristics were studied
using AVL combustion analyser. From the experimental
investigation it was found that the smoke, particulate
matter and Oxides of Nitrogen emissions were reduced
marginally. From the pressure curve and cumulative heat
release curve, it was observed that the combustion started
earlier and the rate of pressure rise increased marginally.

dielectric loss and AC conductivity were studied in
the frequency range of 100 KHz to 3 MHz at
different temperatures. The activation energy was
calculated using Arrhenius plot. The lattice
parameter, grain size, dielectric constant and AC
conductivity of pure LGN ceramics were deeply
affected by Al substitution in pure LGN.
In this paper, the non-invasive
methodology for removing Fetal Electrocardiogram
(FECG) is gained by subtracting the balanced
variation of maternal electrocardiogram (MECG)
movement from the abdominal electrocardiogram
(AECG) banner. The banner assessed from the
mother's guts (AECG) is regularly overpowered by
maternal heartbeat. The maternal portion of the
AECG is the nonlinearly changed variation of
MECG. This paper uses an Adaptive Neuro-Fuzzy
Interference System (ANFIS) structure. It is used
for finding the non-direct change and the ensuing
banner are set up with people based request
figurings. This strategy involves some specific
issues which are a direct result of the low force of
the fetal ECG which is sullied by various
wellsprings of checks. It joins maternal ECG,
electromyogram (EMG) signals, power line
impedances and sporadic electronic upheavals.
Along these lines, we are proposing an improved
multimode PSO estimation for overcoming this
issue. In addition, methods like wavelet change,
flexible filtering, thresholding are moreover used.
We have furthermore empowered the thoracic and
stomach signals using MATLAB programming. It
uses only two signs recorded at the thoracic and
stomach regions of mother's skin. Similarly, our
test shows that the proposed count can expel FECG
banner immediately in pregnancy period and that is
one of the basic focal points of figuring.
Almost since the first days of flight, man has been
concerned with the safe escape from an aircraft, which
was no longer flyable. Early escape equipment
consisted of a recovery parachute only. As aircraft
performance rapidly increased during World War II, it
became necessary to assist the crew members in
gaining clear safe separation from the aircraft. This
was accomplished with an ejector seat, which was
powered by a propellant driven catapult - the first use
of a propulsive element in aircrew escape Since then,
this collection of componentry has evolved through
several generations into today's relatively complex
systems, which are highly dependent upon propulsive
elements. Ejection seats are one of the most complex
pieces of equipment on any aircraft, and some consist
of thousands of parts. The purpose of the ejection seat
is simple: To lift the pilot straight out of the aircraft to
a safe distance, then deploy a parachute to allow the
pilot to land safely on the ground
The current paper is mainly about maintaining a secure
environment and also free from thefts that are happening
in our home. The present paper discusses about the
detection of intruders with the help of the various
devices and software.. OpenCV(open source computer
vision) is the major software that is being used in our
present work. For detecting faces we are using various
algorithms like Haar cascade, linear SVM, deep neural
network etc. The main method that we have proposed in
our work is, if any person comes in front of the pi
camera, first it will look for potential matches that we
have already stored in our system If the module finds a
match then it continues to record until any intruder
comes. If the face is not recognized then the unknown
person’s face will be captured and a snap shot will be
sent to the user’s email. The device is developed using
Raspberry Pi b+ with 1.4 GHz quad core processor,
raspberry pi camera module and a Wireless dongle to
communicate with user’s email.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

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!

I. INTRODUCTION
In recent years various studies have been conducted
on the CNC machining process. The aim of CNC machining
process is to improve the products quality, productivity and
minimize the production cost. To produce good quality
products which depends upon the machining parameters.
The machining parameters are important factors for
improving the products quality.
The surface quality is an important parameter in
turning process to evaluate the quality of products and
machine tools. Machining parameters without optimization
are mainly affecting the surface roughness. Predicting the
surface roughness of AISI 1040 steel with the help of
artificial neural networks and multiple regressions method
and investigation of the effect of
input cutting parameters on the surface roughness. The
multiple regression models are tested by using the analysis
of variance (ANOVA) method. Two different variants are
used in Back-propagation algorithm. The multiple
regression and neural network-based models are compared
with the performance (Asilturk and cunkas, 2011).
To analyze the machinability of AISI 4340 steel
with zirconia toughened alumina ceramic inserts using
Taguchi and regression methods experiments are conducted
based on an orthogonal array L9 with three parameters and
three levels. Experiment was also conducted to find out the
significance and percentage contribution of each parameters
with the help of Analysis of variance (Mandal et al., 2011).
The proper selection of cutting parameters can
minimize the noise factors and the response of surface
roughness. In this method AISI 1020 medium carbon steel is
used as a work piece and to analyze the surface roughness
and work piece temperature. Using these results optimal
cutting parameters can be selected to measure the optimal
cutting parameter for each performance using Taguchi
techniques (Adeel et al., 2010).
Before the machining process surface roughness is
to be determined using ANN method to predict the surface
roughness with different cutting conditions. (Karayel, 2009).
The Surface roughness is an important factor for
the turning process. The major optimum cutting parameters
are speed, feed and depth of cut. By selection optimal
cutting parameters the surface roughness can be minimized.
Using Real Coded Genetic Algorithm optimum cutting
parameters can be selected(Srikanth and kamala, 2008).
Optimal machining parameters like cutting speed, feed rate
and depth of cut have to be selected. Using these parameters
the average of surface roughness (Ra) can be investigated.
In this method 9SMnPb28k (DIN) is used a as a work piece
and cemented carbide inserts with developed the ANN
models. Using error back-propagation training algorithm
(EBPTA) with the knowledge based artificial neural
network training method. To analyze the effect of
machining conditions with

surface roughness parameters. The proper selection of
machining parameters is to produce good surface finish
(Davim et al., 2008).
To increase the productivity and reduction of cost
is depends upon the optimum selection of cutting conditions.
To optimize the complex cutting parameters are using neural
network approach. To all-important turning parameters are
optimized and this approach is suitable for selection of
optimum cutting parameters in turning process (Zuperl and
Cus, 2003).
The aim of this paper approach is comparison of
artificial neural networks and adaptive neuro fuzzy inference
system. To investigate the cutting parameter effects and the
machining parameters are like cutting speed, feed rate, and
depth of cut. The artificial neural network models are
training with tested using back propagation training
algorithm (BPTA). To find the performance of EN8 medium
carbon steel using artificial neural network and adaptive
neuro fuzzy inference system. The proposed model is to
predict the surface roughness effectively. The artificial
neural network produces good results compare to the
Adaptive neuro fuzzy inference system.
II. MATERIALS AND METHODS:
In any turning process we are consider many
factors. Mainly the affecting surface roughness factors are
such as tool variables, work piece variables, and cutting
conditions. Tool variables consist of tool material, nose
radius, rake angle, cutting edge geometry, tool vibration,
tool point angle, etc., The machining input cutting
conditions are speed, feed, and depth of cut and difficult to
select the hard turning process parameters. The appropriate
cutting condition gives good surface quality.
The experiments have been conducted on
straight turning of unalloyed medium carbon steel EN8 on a
lathe by a TNMG and VNMG at different speed, feed and
depth of cut combinations. The Machining process has been
conducted with coolant. The wet conditions under which the
machining parametres are speed, feed, depth of cut. The
experiments conduct using three different parameters with
27 settings.
A. Proposed ANN and ANFIS Model for
Surface Roughness:
The developed ANN model to determine surface roughness
in a wet condition. The capability of the ANN model is to
generalize unseen data dependents on several factors. These
Factors are appropriate selection of input-output parameters,
the distribution of the input-output dataset, and the format of
the presentation of the dataset to the neural network.
Selected input parameters are the significant variables that
affect the surface roughness while perform turning operation
under wet condition. We consider the input parameters are
cutting speed, feed rate and depth of cut. The surface
roughness is the output parameter of the model.
Fig.1 Schematic diagram of ANN for Ra
B. Collection of Input-Output Dataset:
The machining processes have been conducted by
straight turning of unalloyed medium carbon steel EN8 on a
CNC lathe. By using TNMG and VNMG as an insert at
different cutting speeds (V), feed rates (f), depth of cuts (d)
under wet condition. After machining each component and
the average surface roughness value was also measured by a
Kosaka Surf Coder. Thus several pairs of output variables in
response to the different combinations of machining input
parameters have been obtained.
C. Preprocessing Input – Output Dataset:
The capability of the artificial neural network
(ANN) model to generalize regarding unseen data
dependents on several factors such as appropriate selection
of input-output parameters of the system, the distribution of
the input-output dataset, the format of the presentation of
the input-output dataset to the neural network. For our ANN
model, the input parameters used are the three main
machining parameters. The machining parameters are
cutting speed, feed rate and depth of cut. The output process
parameters are average of surface roughness.
P = {Cutting speed , Feed, Depth of cut}
, T = {Surface Roughness}
In this method several machining tests were carried
out and thus 40 pairs of input-output dataset were obtained
during the machining trials. Before training the ANN by
feeding the dataset to the network and the input-output
mapping, one significant task is to process the experimental
data into patterns. Training and testing pattern vectors are
formed before input output dataset are fed to network. Each
pattern is formed with an input condition vector (Pi) and the
corresponding target vector (Ti), which is shown in the
matrix. Before training the network, the input output dataset
were normalized within the range of -1 to +1 using the
MATLAB command ‘mapminmax’.
D. Experimental setup:
Collecting the data sets are from experiments
conducted on a CNC lathe machine in the industry, Chennai,
India. The machining experiments details are given in Table 1.
Two inserts are used in the EN8 machining experiments. In this
experiment totally 27 settings. In Each settings to produced
three components. After the each

turning process to measure the surface roughness(Ra) was
measured with Kosaka Surf coder testing machine. A
program was developed using Matlab7.11 software. The
surface roughness measurements were taken one time for
each work piece. The outputs are measured as 27*3 = 81
samples and their average values are taking as data. In this
method EN8 material is a work piece. It is hardened to 50 -
55 HRC, and then normalization. Tensile properties can vary
but are usually between 500-800 N/mm2. The specimen was
cylindrical bar with 25.5 mm diameter and 26 mm length.

Company. The cutting parameters were selected to that the
measured cutting forces. The suggested input cutting
parameters values are shown in Table 1. The cutting
conditions unchanged and all experiment was conducted
with two inserts with two different operations. The
experiments conducted on with coolant and totally 27
different settings using to conduct the experiments were
performed according to full factorial design. The surface
roughness parameters are generally depends on the input
cutting parameters. like cutting speed, feed rate, depth of cut
machining tool and cutting tool rigidity. In this method the
three main input cutting parameters was selected. The input
cutting parameters are cutting speed (V), feed (f), and depth
of cut (d). The EN8 material experimental datas and

III. RESULTS AND DISCUSSION:
In this section, the results obtained from the
artificial neural networks and Adaptive neuro fuzzy
inference system are compared and discussed.
3.1 Artificial neural network:
Multilayer perception structure that is a kind of
feed-forward ANNs was applied to model and predict the
surface roughness in turning operations. The experimental
data presented in Table 2were utilized to build the ANN
model. The back-propagation training algorithms, the
Gradient descent method and Levenberg – Marquardt (LM),
were used for ANNs training. The best results were obtained
with this algorithm compared to other training algorithms.
Two ANNs structure, 3-2-1 and 3-3-1, were tested. The
meaning is 1 node is a output layer, 2/3 node hidden layer,
and 3 node input layer for input variables. The neural
networks software was coded using the Mat lab 7.11 Neural
Network Toolbox. The learning parameters of the proposed
ANN structure are presented.

3.3 Overall Comparison:
The experimental data set consists of 27 patterns, of
which 18 patterns were used for training and testing the
performance of the trained network. After the network has
successfully completed the training stage, it was tested with
the experimental data that were not present in the training
data set. The ANN and ANFIS results are compared. The
results obtained show that ANN produces the better results
compared to Adaptive neuro fuzzy inference system.
IV. CONCLUSION:
In this method, artificial neural network and
adaptive neuro fuzzy inference system approaches were
used to predict the surface roughness in EN8. The
parameters such as cutting speed, feed, and cutting of depth
were measured by means of full factorial experimental
design. The data obtained were used to develop the surface
roughness.
The feed rate is the dominant factor affecting the
surface roughness, followed by cutting of depth and cutting
speed. The back-propagation training algorithms, the
gradient descent method and Levenberg–Marquardt (LM),
were used for ANNs training. The best result having the
optimization parameters was obtained by Gradient descent
method with 2 neurons.
The developed models were evaluated for their
prediction capability with measured values. The predicted
values were found to be close to the measured values. The
proposed models can be used effectively to predict the
surface roughness in turning process. The effective
percentage is 99% for neural network model, while it is
achieved as 90% for adaptive neuro fuzzy inference system.
Considering that advantages of the ANN compared
to adaptive neuro fuzzy inference system are simplicity,
speed, and capacity of learning, the ANN is a powerful tool
in predicting the surface roughness.
