Finite Element Analysis of Single Point Cutting ToolIJMER
In this project, temperature at tool-tip interface is determined, generated in high-speed machining operations. Specifically, three different analyses are comparing to an experimental measurement of temperature in a machining process at slow speed, medium speed and at high speed. In addition, three analyses are done of a High Speed Steel and of a Carbide Tip Tool machining process at three different cutting speeds, in order to compare to experimental results produced as part of this study. An investigation of heat generation in cutting tool is performed by varying cutting parameters at the suitable cutting tool geometry. The experimental results reveal that the main factors responsible for increasing cutting temperature are cutting speed (v), feed rate (f), and depth of cut (d), respectively. It is also determined that change in cutting speed and depth of cut has the maximum effect on increasing cutting temperature. Various researches have been undertaken in measuring the temperatures generated during cutting operations. Investigators made attempt to measure these cutting temperatures with various techniques during machining.
In this project, “Fluke 62 max IR thermometer” (Range -40 0C to 650 0C) is used for measuring temperature at tool-tip interface. Single point cutting tool has been solid modeled by using CAD Modeler Pro/E and FEA carried out by using ANSYS Workbench 14.5. Experimental work is done at “Khushi Engineering”, Nagpur.
By varying various parameters the effect of those on temperature are compared with the experimental results and FEA results. After comparison nearly 4% variation is found in between the results.

Abstract: Finite element method has gained immense popularity in the area of metal cutting for providing detailed insight in to the chip formation process. This report presents an overview of the application of finite element method in the study of metal cutting process. The basics of both metal cutting and finite element methods, being the foremost in understanding the applicability of finite element method in metal cutting, have been discussed in brief. In this project, thermo mechanical simulation of turning process has been developed using commercially available finite element analysis software, ABAQUS 6.10. A 2-D orthogonal cutting has been modelled using an Arbitrary Lagrangian - Eulerian (ALE) formulation. The Johnson-Cook plasticity model has been assumed to describe the material behaviour during the process. Adaptive meshing dynamic explicit is also employed in this model to avoid the severe deformation. This study is aimed at temperature and stresses distributions during machining of AISI 1050 steel with three different speed 120m/min, feed 0.1 mm/rev. and depth of cut 1.5 mm. The results showed for speed 120 m/min, feed 0.1 and depth of cut 1.5 that the maximum stress for -7oC rake angle is 1.35 GPa while the maximum temperature results shown that 699°C.

Query Answering Approach Based on Document SummarizationIJMER
The growing of online information obliged the availability of a thorough research in the
domain of automatic text summarization within the Natural Language Processing (NLP)
community.The aim of this paper is to propose a novel approach for a language independent automatic
summarization approach that combines three main approaches. The Rhetorical Structure Theory
(RST), the query processing approach, and the Network Representationapproach (NRA). RST, as a
theory of major aspect for the structure of natural text, is used to extract the semantic relation behind
the text.Query processing approachclassifies the question type and finds the answer in a way that suits
the user’s needs. The NRA is used to create a graph representing the extracted semantic relation. The
output is an answer, which not only responses to the question, but also gives the user an opportunity to
find additional information that is related to the question.We implemented the proposed approach. As a
case study, the implemented approachis applied on Arabic text in the agriculture field. The
implemented approach succeeded in summarizing extension documents according to user's query. The
approach results have been evaluated using Recall, Precision and F-score measures.

The main purpose of this research is to study the optimal process parameters for thermal friction drilling process on AISI 304 stainless steel. The experiments were conducted based on Taguchi experimental design method, and the multiple performance characteristics correlated with the resultant axial force, radial force, hole diameter dimensional error, roundness error, and bushing length, were investigated by fuzzy logic technique. The significant process parameters that most intensively affected the multiple performance characteristics and the optimal combination levels of process parameters were determined through the analysis of variance and the response graph. A test rig was manufactured at Shoman Company ‒ Egypt to perform the experimental work, and the tools were offered by Flowdrill Company ‒ Germany. Experimental results confirm that this approach is simple, effective and efficient for simultaneous optimization of multiple quality characteristics in thermal friction drilling process, as the bushing length produced is more than five times the workpiece thickness.

Abstract The aim of this study is to create a finite element analysis simulation model in order to obtain solutions of the cutting forces, specific cutting energy and adequate temperatures occurring at different points through the chip/tool contact region and the coating/substrate boundary for a range of cutting tool materials and defined cutting conditions. Interfacial temperature in machining plays a major role in tool wear and can also result in modifications to the properties of the work piece and tool materials. As there is a general move towards dry machining, for environmental reasons, it is increasingly important to understand how machining temperature are affected by the process variables involved (cutting speed, feed rate, tool geometry, etc.) and by other factors such as tool wear.

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.

Geochemistry and Genesis of Kammatturu Iron Ores of Devagiri Formation, Sandu...IJMER
The Greenstone belts of Karnataka are enriched in BIFs in Dharwar craton, where Iron
formations are confined to the basin shelf, clearly separated from the deeper-water iron formation that
accumulated at the basin margin and flanking the marine basin. Geochemical data procured in terms of
major, trace and REE are plotted in various diagrams to interpret the genesis of BIFs. Al2O3, Fe2O3 (T),
TiO2, CaO, and SiO2 abundances and ratios show a wide variation. Ni, Co, Zr, Sc, V, Rb, Sr, U, Th,
ΣREE, La, Ce and Eu anomalies and their binary relationships indicate that wherever the terrigenous
component has increased, the concentration of elements of felsic such as Zr and Hf has gone up. Elevated
concentrations of Ni, Co and Sc are contributed by chlorite and other components characteristic of basic
volcanic debris. The data suggest that these formations were generated by chemical and clastic
sedimentary processes on a shallow shelf. During transgression, chemical precipitation took place at the
sediment-water interface, whereas at the time of regression. Iron ore formed with sedimentary structures
and textures in Kammatturu area, in a setting where the water column was oxygenated.

Non linear analysis of Robot Gun Support Structure using Equivalent Dynamic A...IJMER
Robot guns are being increasingly employed in automotive manufacturing to replace
risky jobs and also to increase productivity. Using a single robot for a single operation proves to be
expensive. Hence for cost optimization, multiple guns are mounted on a single robot and multiple
operations are performed. Robot Gun structure is an efficient way in which multiple welds can be done
simultaneously. However mounting several weld guns on a single structure induces a variety of
dynamic loads, especially during movement of the robot arm as it maneuvers to reach the weld
locations. The primary idea employed in this paper, is to model those dynamic loads as equivalent G
force loads in FEA. This approach will be on the conservative side, and will be saving time and
subsequently cost efficient. The approach of the paper is towards creating a standard operating
procedure when it comes to analysis of such structures, with emphasis on deploying various technical
aspects of FEA such as Non Linear Geometry, Multipoint Constraint Contact Algorithm, Multizone
meshing .

Natural Language Ambiguity and its Effect on Machine LearningIJMER
"Natural language processing" here refers to the use and ability of systems to process
sentences in a natural language such as English, rather than in a specialized artificial computer
language such as C++. The systems of real interest here are digital computers of the type we think of as
personal computers and mainframes. Of course humans can process natural languages, but for us the
question is whether digital computers can or ever will process natural languages. We have tried to
explore in depth and break down the types of ambiguities persistent throughout the natural languages
and provide an answer to the question “How it affects the machine translation process and thereby
machine learning as whole?” .
Today in era of software industry there is no perfect software framework available for

the help of Likert scale we define a rule based model and delegate some mass score to every process and
develop one tool name as MuxSet which will help the software developers to select an appropriate
development process that may enhance the probability of system success.
Material Parameter and Effect of Thermal Load on Functionally Graded CylindersIJMER
The present study investigates the creep in a thick-walled composite cylinders made
up of aluminum/aluminum alloy matrix and reinforced with silicon carbide particles. The distribution
of SiCp is assumed to be either uniform or decreasing linearly from the inner to the outer radius of
the cylinder. The creep behavior of the cylinder has been described by threshold stress based creep
law with a stress exponent of 5. The composite cylinders are subjected to internal pressure which is
applied gradually and steady state condition of stress is assumed. The creep parameters required to
be used in creep law, are extracted by conducting regression analysis on the available experimental
results. The mathematical models have been developed to describe steady state creep in the composite
cylinder by using von-Mises criterion. Regression analysis is used to obtain the creep parameters
required in the study. The basic equilibrium equation of the cylinder and other constitutive equations
have been solved to obtain creep stresses in the cylinder. The effect of varying particle size, particle
content and temperature on the stresses in the composite cylinder has been analyzed. The study
revealed that the stress distributions in the cylinder do not vary significantly for various combinations
of particle size, particle content and operating temperature except for slight variation observed for
varying particle content. Functionally Graded Materials (FGMs) emerged and led to the development
of superior heat resistant materials.

NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

I. INTRODUCTION
Research in metal cutting was started with Cocquilhat in 1851 which measured the work required to
remove a given volume of material in drilling. The attempt made by Time led to the explanation of formation of
chips in 1870 and further research was made by Tresca in 1873. Later in 1881, Mallock suggested that the
cutting process was the shearing of workpiece to form the chip and emphasized the importance of the effect of
friction occurring on the cutting tool face as the chip was removed. Further, Taylor investigated the effect of tool
material and cutting conditions on tool life during rough operations. Latest fundamental work has been carried
out by Ernst and Merchant in 1941 dealing with the mechanics of metal cutting process. The simplest and most
widely used model for cutting was first by Ernest and Merchant (1941) and further contribution to study of
Ernest and Merchant theory was done by Lee and Shaffer (1951), Kobayashi and Thomsen (1962). Large
number of literature is available on the determination of chip-tool interface temperature, factors affecting the
interface temperature and techniques of optimization of machining parameters including cutting speed, feed rate,
cutting zone temperature, etc. Armerago (1969), Boothroyd (1981), Shaw (1984) and Trent (2000) wrote the
most widely used text books. Kalpakjian, et al. (2006), and DeGarmo, et al. (1997) wrote books on more general
introductory knowledge. The study machining process by experimental approach is expensive and time
consuming peculiarly when a wide range of parameters is included like tool geometry, cutting conditions, and
materials.
II. LITERATURE REVIEW
Jensen M.R. et al. [1] stated that an important problem in the machining of drawn parts is tool wear.
They said that tool wear can be reduced by increasing the tool lifetime and by making more continuous
production flow, by reducing the number of break-downs when the tools have to be re-polished. In their paper,
an optimization of the shape of the draw-die profile with regard to wear was carried out using a conventional
optimization method and explicit finite element. The optimized draw-die profile had almost twice the tool life
compared to that of the initial circular draw-die, if the peak value of wear was used as the wear criteria. The
relatively small resources used by them with their optimization approach made the tool wear design relevant for
industrial use at the tool-design state.
Sullivan D.O’ et al. [2] determined the temperature in a single point turning process. The total work
done by a cutting tool in removing metal was determined from the force components on the cutting tool.
Approximately, all of this work or energy is converted into heat which is dissipated into the chip, tool and
workpiece material. The wear of the tool is related to the cutting forces. Initial experiments conducted involved
the simultaneous measurement of forces and temperatures. These experiments focused on the use of embedded
thermocouple (in the work piece) and using the infrared thermal camera to monitor the process. They concluded
that in machining of aluminium Al 6082-T6 the decreased cutting tool forces and machined surface
temperatures was resulted by increased cutting speed (VC) and increased cutting tool forces and machined
Abstract: The quality of the machined piece and tool life are greatly influenced by determination of
maximum temperature of the cutting tool. Numerous researchers have approached to solve this problem
with experimental, analytical and numerical analysis. There is hardly a consensus on the basics principles
of the thermal problem in metal cutting, even though considerable research effort has been made on it. It is
exceedingly difficult to predict in a precise manner the performance of tool for the machining process. This
paper reviews work on the requirements for optimization of Tool wear so that its life could easily be
predicted.

surface temperature was resulted by tool wear. They left the examination of temperature distribution at the tool
chip interface for the future work.
Abukhshim N.A. et al. [3] reviewed the previous research work. Research on heat generation and heat
dissipation in the orthogonal machining process is critically studied. In addition, temperature measurement
techniques applied in metal cutting were also reviewed. The emphasis was on the comparability of test results
obtained by a thermal imaging camera in high speed cutting of high strength alloys. Finally, latest work on these
topics in metal machining was also reviewed. They reviewed the methods of temperature measurement and the
analytical and numerical models for the prediction of temperature and temperature distribution in metal cutting.
In metal cutting the Prediction of cutting temperatures is a major challenge. They concluded that fiber-optic
pyrometers and infrared thermography techniques for temperature measurement of the high speed cutting
process are more promising as compared to other methods as these techniques can measure temperature, as well
as, the cooling rate easily, accurately and with fast time response. They stated that technology for consideration
of interactions at the tool/chip interface is mainly based on certain assumptions and not on a precise
understanding of the underlying physics. They also stated that modeling and simulation of machining processes
is mainly suffering from a lack of the fundamental input data.
Many researchers has been undertaking into measuring the temperatures generated during cutting operations.
Investigators have attempted to measure these cutting temperatures with various techniques (see figure 1 based
on [4])
Figure 1: Temperature measurement in machining [4]
Lazoglu Ismail et al. [5] predicted the tool chip temperature in continuous and interrupted machining.
They presented a numerical model based on the finite difference method to predict tool and chip temperature
fields in continuous and interrupted machining and time varying milling processes. By modeling the heat
transfer between the tool and chip at the tool-rake face contact zone Continuous or steady state machining
operations like orthogonal cutting were studied. They determined Heat balance equations in partial differential
equation forms for the chip and for the tool. The solutions of the steady-state tool and chip temperature fields
were taken by finite difference method. The chip thickness was discretized along the time to determine the
transient temperature variation in the case of interrupted machining.
Sutter G. et al. [6] presented an experimented setup for the measurement of temperature field in high
speed machining. Their paper presented an experimental setup during an orthogonal machining operation with
42 CrMo 4 steel. The technique of temperature measurement was developed on the principle of pyrometer in the
visible spectral range by using an intensified CCD camera with very short exposure time and interference filter
at 0.8 micrometer. They obtained the temperature gradients in an area close to the cutting edge of the tool, along
the secondary shear zone. It was established that their experimental arrangement shown in Figure 2 was quite

efficient and can provide fundamental data on the temperature field in material during orthogonal high speed
machining. They showed experimentally that, for a cutting speed of 20 m/s a hot spot was located near the tool-
chip interface at a distance of 300-350 μm of the tool tip. This value corresponds to about the two-thirds of the
depth of cut. The reaching temperature is around 825°C. The temperature in the chip increases with increasing
of the cutting speed. Their result showed that, with an increase of the cutting speed from 20–30 m/s the
dependence of the temperature on the cutting speed was more noticeable. They even showed that, the
temperature appeared to stabilize for the cutting speeds larger than 40 m/s. A similar tendency was observed
with the increasing in the depth of cut and for a cutting speed fixed to 40 m/s by their experimental technique.
The temperature in the chip was nearing a saturated value about of 840°C during the process of an un-deformed
chip thickness larger than 0.5 mm.
Figure 2: Experimental Apparatus’s scheme used by G. Sutter et al. [6]
Dogu Yahya et al. [7] designed a numerical model to determine temperature distribution in orthogonal
metal cutting. In their study, they developed a thermal analysis model to determine temperature distribution in
orthogonal in metal cutting using FEM. Their model was used to calculate the temperature distribution as a
function of heat function of heat generation. Assuming that all the work required for cutting is converted to the
sensible heat energy the amount of heat generation was calculated by them. Accurate predictions of temperature
field over the entire cutting zone were given by the developed model. It was also found that at the half of the
contact length from cutting edge, the maximum temperatures for relatively smaller cutting speeds occurred for
the analyzed cases. It was clear that the outer surface of the material will be subject to higher heat removal and
sudden temperature drop.
Saglam Haci et al. [8] studied the effect of tool geometry and cutting speed on main cutting force and
tool tip temperature. They investigated the temperature generated on the tip of the tool in turning and cutting
speed on cutting force components and the effects of rake angle and entering angle in geometry of tool in their
paper. The experiments were conducted on a CNC lathe to derive the data used for investigation. Each test was
conducted with a sharp uncoated tool insert, while keeping the depth of cut and feed rate constant, during the
tests. They found that the cutting speed was effective on the tool tip temperature, while the rake angle was
effective on all the cutting force components. They found that, the deviation in temperature was 54%, while the
average deviation between calculated and measured values of main cutting force was 0.26% in 64 numbers of
experiments.

Figure 3: Experimental setup used by Saglam et al. [8].
They experimentally found that the main cutting edge subjected to maximum loading and unloading as it
enters and leaves the cutting zone abruptly at 90o
of entering angle by using the experimental setup shown in
Figure 3. They also found that the impact of load was not exerted on cutting tool when it has an entering angle
different then 90o
, because the cutting edge enters and leaves the workpiece gradually. Hence, they concluded
that at 60o
to 70o
the optimum entering angle was obtained. They showed that, the cutting forces were reduced
and the temperature was increased when the cutting speed was raised. They also showed that, the cutting forces
were decreased, for the increased positive rake angle. Their result of cutting forces and temperature evaluated
together resulted that the optimum rake angle should be 12o
. Their results of analysis of variance evaluated, that
the cutting speed was effective on tool tip temperature while, the rake angle had a significant effect on cutting
forces components. They verified their conclusions by the correlation coefficients.
Ueda Takashi et al. [9] determined the temperature of a signal crystal diamond tool in turning. They in
precision turning, investigated experimentally and theoretically the temperature on the rake face of a single
crystal diamond tool. They used FEM to calculate the temperature distribution in the tool and in the work piece
numerically. Two-color pyrometer with an optical fiber was used by them to measure the temperature on the
rake face of a single crystal diamond tool in precision turning and then they calculated numerically using FEM.
They showed that, regardless of the size of the object, the two-color pyrometer is capable of measuring the
temperature when the temperature of the object is constant.
Figure 4: Experimental setup used by Ueda Takashi et al. [9]
They experimentally concluded that, it is possible to estimate the maximum temperature from the
measured temperature, when the object has a surface of known temperature distribution. They also concluded
that, when the object has a surface of known temperature distribution, it is possible to estimate the maximum
temperature from the measured temperature and the increase in cutting speed increases the temperature on the
rake face. Their measured values of temperatures in the experiment agreed well with their calculated results
numerically using FEM.
Tanikic et al. [10] studied the metal cutting process parameters modeling using artificial neural network
(ANN) and hybrid, adaptive neuro fuzzy systems. The main aim of their experiment was to conduct the
qualitative analysis of metal cutting processes, and also identifying and resolving the frequently occurring
problems, while improving the productivity of metal cutting by reducing the manufacturing costs. The infrared
camera was used to measure and monitor the temperature at the chip tool interface. They also, modeled the

measured data by using ANN and neuro fuzzy system. Their work concluded that, the implementation of
artificial intelligence based systems in metal cutting process is possible. In the end, they proposed the global
system for predicting the state of cutting tool along with sub-systems for cutting temperature, cutting force and
arithmetic mean deviation prediction.
Figure 5: Component relations and information flow of material handling system
Fata [11] proposed the method of embedded thermocouple for temperature measurement along with
infrared pyrometer. The experiments are conducted for dry and orthogonal machining condition with
simultaneous measurement of temperature by embedded thermocouple and infrared pyrometer. With the help of
these experiments a relation was established between tool temperature and cutting parameters such as cutting
speed, feed rate and depth of cut. The results so obtained showed that if cutting speed, feed rate and depth of cut
are increased then the tool temperature also increases which reduces the life of the cutting tool. These
investigations revealed that the most effective cutting parameter in tool temperature rise is the cutting speed,
especially at high range of cutting conditions. It also showed an increase in feed rate and depth of cut will lead
to an almost straight line with low slope on the graph of tool temperature when plotted against them.
Adnan Jameel et al. [12] focused their study on the temperature generated at two heat zones namely
primary heat zone (shear zone) and secondary heat zone (tool chip interface zone). They proposed two new
objective functions for optimizing the cutting temperature problems and this system used particle swarm
optimization (PSO) methodology to determine the optimal temperature. Their experiments showed that major
amount of energy is converted into heat in the shear zone while the heat generated at the tool chip interface zone
is due to the rubbing action at that interface. They concluded that heat distribution pattern is dependent on the
size and thermal conductivity of the tool-work material and the cutting conditions. Specifically the results were
obtained for mild steel work and carbide insert cutting tool in dry turning operation. Their study concluded that
main cutting force, feed rate and depth of cut greatly influence the shear zone temperature while chip thickness
and friction force have low effect. They also concluded that, the chip tool interface temperature increased with
increase in feed rate and main cutting force while it decreased with increase in the depth of cut. Their whole
study of paper concluded that feed rate has a huge effect on shear zone and chip tool interface zone temperature
as compared to other parameters. Their study also concluded that till date the nearly all of optimization
algorithms concentrated to optimize parameters are other than cutting temperature and according to their studies
there are few papers focusing on the cutting temperature optimization.
Shirpurkar P.P. et al. [13] attempted to review the literature on optimization of machining parameters in
turning processes by using different tool inserts. During their review of different conventional techniques
employed for optimization of parameters were also studied by them. These techniques include geometric
programming, geometric plus linear programming, non-linear programming, goal programming, sequential
unconstrained minimization technique and dynamic programming. Later the latest optimization techniques were
also discussed by them, specifically Taguchi technique, genetic algorithm, fuzzy logic and ant colony technique.
These techniques were successfully applied in the industrial applications for optimal selection of process control
variables. The paper concluded that Taguchi approach has the potential for savings in experimental time and
cost on product or process, development and quality improvement and therefore is widely used in industries.
According to their review, in most of the industries the skill, experience and mentality of the operators are the
primary factors affecting the turning process parameters and surface roughness on the job/work piece. Therefore
to attain minimum surface roughness it was very necessary to optimize the turning process parameters. Their

review concluded that the latest optimization techniques like Taguchi technique, genetic algorithm, Fuzzy logic
and response surface methodology are being applied successfully in industrial applications for optimal selection
of process variables in the area of machining.
Yen et al. [14] stated that the tool wear on the tool–workpiece and tool–chip interfaces in metal cutting
(i.e. crater wear and flank wear) are strongly influenced by the relative sliding velocity and cutting temperature
at the interface. Their study’s overall objective was to develop a methodology to tool life in orthogonal cutting
and predict the tool wear evolution using FEM simulations. To approach their goal, the methodology proposed
by them had three different parts. In the first part, a tool wear model for the specified tool–workpiece pair was
developed by them via a calibration set of tool wear cutting tests in conjunction with cutting simulations. In the
second part, they modified the commercial FEM code, which was used to allow tool wear calculation and tool
geometry updating. The last part was experimental validation of the developed methodology.

The maximum wear rate was clearly located on the tool rake face as shown in Figure 7. Nevertheless,
they predicted small wear rates on the flank side of the tool edge radius, which were about one order of
magnitude smaller than the rake face wear rates. They showed that the experimental results for uncoated carbide
tools depicted that crater wear and flank wear on the tool face occur simultaneously at a similar wear rate [15].

The initial results of tool wear simulations obtained by them using the developed method tend to
underestimate the wear rates associated with the flank wear and crater wear, when the tool life was compared
with the measured data obtained at the same conditions. They concluded that the reason to underestimate the

wear rates associated with the flank wear and crater wear may be partially due to the fact that the two wear
constants in Usui’s wear model were directly borrowed from the literature [16].
Thamizhmanii et al. [18] applied Taguchi method under optimum cutting condition for finding out the
optimal value of surface roughness in turning SCM 440 alloy steel. They detected that the tool chattering and
machine tool vibrations were the causes of poor surface finish whose effects were ignored by them for analysis.
The authors concluded that that depth of cut of 1 to 1.5 mm can be used to get lowest surface roughness, and the
only significant factor was depth of cut which, contributed to the surface roughness.
Kilickap [19] investigated the use of the Taguchi method and the Response Surface Methodologies
(RSM) for minimizing the burr height and the surface roughness in drilling Al-7075. The optimization results
showed that to minimize burr height, the combination of low cutting speed, low feed rate and high point angle
were necessary. At the combination of lower cutting speed and feed rates and at higher point angles the lowest
values of surface roughness were obtained. In his paper he presented an application of response surface
methodology (RSM) and Taguchi method for selecting the optimum combination values of drilling parameters
affecting the burr height and surface roughness in dry drilling of Al-7075. He also concluded that to perform
trend analysis of the surface roughness and the burr height with respect to various combinations of drilling
parameters Taguchi method is the most successful technique. The analysis of experiments perfumed by him has
shown that Taguchi method can be successfully used to verify all the optimum cutting parameters.
III. SUMMARY
Experiments revealed that, the tool wear can be reduced by increasing the tool lifetime and by making
more continuous production flow. The total work done by a cutting tool in removing metal was determined from
the force components on the cutting tool. If cutting speed, feed rate and depth of cut are increased then the tool
temperature also increases which reduces the life of the cutting tool. The chip tool interface temperature
increased with increase in feed rate and main cutting force while it decreased with increase in the depth of cut.
This review concluded that the decreased cutting tool forces and machined surface temperatures was resulted by
increased cutting speed (VC). It also revealed that, increased cutting tool forces and machined surface
temperature was resulted by tool wear and the temperature in the chip increases with increasing of the cutting
speed. Experiments also showed that, the temperature appeared to stabilize for the cutting speeds larger than 40
m/s and the temperature in the chip was nearing a saturated value during the process of an un-deformed chip
thickness larger than 0.5 mm. It is now clear from the above that the outer surface of the material will be subject
to higher heat removal and sudden temperature drop. The cutting forces were decreased, for the increased
positive rake angle. The implementation of artificial intelligence based systems in metal cutting process is
possible. The latest optimization techniques like Taguchi technique, genetic algorithm, Fuzzy logic and response
surface methodology are being applied successfully in industrial applications for optimal selection of process
variables in the area of machining. The maximum wear rate is located on the tool rake face. The crater wear and
flank wear on the tool face occur simultaneously at a similar wear rate.
IV. FUTURE SCOPE
The future work may require validation of the proposed methodology [14] for selected cutting
conditions, different from those in the calibration set by predicting tool wear curves, and comparing the results
with the experiments. It may also require use of other wear rate models available in the literature (e.g. Takeyama
and Murata’s wear model [17]). From the above review one can optimize the turning process parameters like
depth of cut, speed, feed, nose radius, material and type of tool, and even work piece material etc using Taguchi
method for maximizing the tool life and minimizing the surface roughness by experimental setup. Taguchi
technique will help to finalize the number of levels with orthogonal array and thus finalizing the number of
experiments. Also the signal to noise ratio will help to observe the behavior of quality characteristics of work
piece.
