DESIGN AND FABRICATION OF PORTABLE DRILLING AND BORING MACHINEvivatechijri
In India, the growth of manufacturing depends largely on its productivity. Productivity depends upon
many factors, one of the major factors are the portability and compactness along with the manufacturing
efficiency with which the operations are carried out in the industry. Productivity can be improved by automation
of machines and combining the different operations in a single machine etc. Drilling and boring are the major
processes involves in manufacturing of most of the industrial as well as commercial products. In the large scale
industry for performing the drilling and boring operations special, heavy duty machines are used but the down
side of this machines are high initial as well as maintenance cost, large space, skilled workers etc. However, in
case of small scale industry the scenario is completely different, because of lack of space, low capital investment,
unskilled workers etc. they cannot afford heavy duty machines. In This paper, a system is proposed to simplify a
drilling and boring operation by using a gear system and a simple mechanism incorporate in a single machine.
The aim of this paper is to generate a new concept to combine and perform drilling and boring operation
effectively and efficiently.

In recent times, manufacturing industries have shown more interest towards Automation. In other
words, the industries today emerge with evolving technology. It is obvious that Industrial Automation streamlines
the operations in terms of speed, reliability and product output. In this thesis, welding fixture for two wheeler
steering handle is modeled using CATIA software, forces are calculated, and an analysis has been carried out in
the precisions placing of one circular component over another circular component during the welding process.
Welding circular rod over another circular rod, the possibility of maintaining the accuracy in placing of curved
surfaces is very less in the mass production. Here the difficulty is overcome by the new design of the fixture, and
the angle as well as the linear movements is maintained in the accuracy of 0.1 mm without any robots. In the field
of welding engineering where a consistently good quality, low cost with a maximum productivity is a must, this
accuracy canbe done by without automation. Welding fixtures are available in different size, shapes, materials
and mechanisms based on their need of operations. The precision of the fixture play a major role in the
manufacturing component. Batch production is the commonly used method in various small and large industries.
Welding a curved surface over an another curved surface is very challenging so is positioning the components.
In mass production, positioning a job takes significant amount of time due to manual process. To overcome this
challenge, theoretical approach has been carried out on the fixture like design fabrication and analysis.

Modelling and Analysis of CNC Milling Machine Bed with Composite Materialijsrd.com
Structural materials used in a machine tool have a decisive role in determining the productivity and accuracy of the part manufactured in it. The conventional structural materials used in precision machine tools such as cast iron and steel at high operating speeds develop positional errors due to the vibrations transferred into the structure. Faster cutting speeds can be acquired only by structure which has high stiffness and good damping characteristics. Clearly the life of a machine is inversely proportional to the levels of vibration that the machine is subjected. The further process is carried out to undergo the deformation, natural frequency and displacement using Static analysis, Modal analysis and Harmonic analysis respectively. Since the bed in machine tool plays a critical role in ensuring the precision and accuracy in components. It is one of the most important tool structures which tend to absorb the vibrations resulting from the cutting operation. To analyze the bed for possible material changes that could increase stiffness, reduce weight, improve damping characteristics and isolate natural frequency from the operating range. This was the main motivation behind the idea to go in for a composite model involving High Modulus Carbon Fiber Reinforced Polymer Composite Material (HM CFRP). Though carbon has good strength and stiffness properties but it lacks in damping requirements. On the other hand polymer, though it lacks in strength but it has good damping characteristics and it is used to hold the carbon fibers. This makes it ideal to combine these materials in a proper manner. In this work, a machine bed is selected for the analysis static loads. Then investigation is carried out to reduce the weight of the machine bed without deteriorating its structural rigidity. The 3D CAD model of the bed has been created by using commercial 3D modelling software and analyses were carried out using ANSYS.

Parametric study on an industrial structure for various dynamic loadseSAT Journals
Abstract
Industrial machinery produce vibrations during its operation. Vibrations are transmitted to structure. However, an industrial structure is designed for these dynamic effects. But there are some dynamic effects which still to be considered. Those are, wind, earth quake and accidental blast loads. Though these loads are not frequent, but its occasional appearance will destroy the structure. An industry with thousands of labours, if gets these occasional dynamic effect, then it might result in much fatal. Therefore an industrial structure must be designed in such a way, that it resists the force created by these dynamic effects and dissipates in a better manner. This study is a numerical analysis of an industrial structure, subjected to wind, earthquake and blast load. The results are compared for severity, and the remedial measures shall be discussed. By adopting the remedial measures, the analysis shall be performed again and the effects will be compared with the earlier results of a normal structure. Drafting software Auto CAD is used for modelling the structure and SAP 2000 analysis software will be used for dynamic analysis. The purpose of this research project work is to study and understand the behavior of structure for dynamic loadings.

finite element analysis & design optimization of material handling equipmentINFOGAIN PUBLICATION
Material handling equipment is mechanical equipment used for the movement, storage, control products throughout the process of manufacturing, and disposal. The different types of material handling equipment can be classified into four major categories, transport equipment, positioning equipment, unit load formation equipment, and storage equipment. Excavator is used to excavate the material of the ground on which the machine rests and load it into trucks or tractor. In the severe working conditions, excavator parts are subjected to very high loads. The excavator mechanism must work reliably under random working conditions. Thus it is very much essential for the designers to evaluate not only a equipment of maximum reliability but also of minimum weight and cost, considering design safe under all loading conditions. It can be accomplished that, mechanical strength analysis is an important to step in the design of excavator parts. Finite Element Analysis (FEA) is the most appropriate technique in strength calculations of the structures working under known load and boundary conditions. In general, computer aided drawing model of the parts to be analyzed must to be set prior to the FEA. It is also promising to reduce the weight of the mechanism by performing optimization in FEA. This paper provides the platform for proceeding for the Modeling, FEA and optimization of backhoe excavator attachment, which was already carried out by other researchers for their related applications and it can be very helpful for development of any material handling equipment and new excavator attachment.
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.

ABSTRACT
With the advancement of technology in the field of industry, high speed machinery has been developed. As the
speed of machinery has increased, vibrations also increased. Machines transmit vibrations to the structure
supporting them. Hence, it is important to design and develop such structure which sustains the vibrations of
machinery. Hence, in this study it has been aimed to execute the study on foundations supporting rotary type of
machine like blower. In this paper, the most important parameters like frequency and amplitude are considered
while execution of analysis of machine foundation supporting blower type machine.
This paper shows, better interface between foundation designer and machine manufacturer for better
performance of machine. The design aids/approaches for foundation design is also described in this paper and an
attempt has been made to study the dynamic behaviour of a foundation structure for blower type machine
subjected to forces due to operation of blower machine. Two different types of foundations for Rotary type
Machine that is Blower have been studied in this paper

I. Introduction
To define the loads to establish performance
criteria, to check resonance condition, to limit
amplitude vibration, to proportion various structural
members of foundation etc. are the key issues in the
design of machine foundation. Yet, behind this
straightforward definition lies the need for careful
attention to the interfaces between machine,
mounting system, and concrete foundation. The basic
goal in the design of a machine foundation is to limit
its motion to amplitudes that neither threaten the
satisfactory process of the machine nor disturb people
working in the immediate vicinity. Many engineers
with varying circumstances are engaged in the
analysis, design, construction, maintenance, and
repair of machine foundations. Therefore, it is
important that the owner/operator, geotechnical
engineer, structural engineer, and equipment supplier
collaborate during the design process. Each of these
contributors has inputs and concerns that are
important and should be effectively communicated
with each other, especially considering that machine
foundation design procedures and criteria are not
covered in building codes and national standards.
Some firms and individuals have developed their own
standards and specifications as a result of research
and development activities, field studies, or many
years of successful engineering or construction
practices. The cost of the machine foundation is but a
small fraction of that of the equipment and
incompetently constructed foundations may result in
failures and closures exceeding many times the cost
of the capital investment required for properly
designed and built foundations. A more detailed
study became urgent because of the development of
machines of higher capacities. Machines of higher
ratings gave rise to significantly greater stresses
thereby posing problems with respect to performance
and safety. Hence it becomes compulsion for
development partly in the field of vibration technique
and partly in that of soil mechanics. J. G. Sieffert
discussed about the recent development in the field&
also discussed about the dynamic soil-structure
interaction. William E.Saul & Thomas W. Wolf have
mentioned that the use of piling for machine
foundation can add flexibility for designer, It help to
solve special problem and possibly reduce the cost.
Z. Huaug & S. Hindiya have explained how the cost
of an existing foundation for machine can be
minimized by optimizing the parameters. The
parameters include the thickness of concrete in the
machine pit and platform. The cross-sectional area
and the amount of reinforced in piles & the no of
piles & the spacing between them. Indrajit
Chowdhury stated that foundation of dynamic
loading are basically designed as per IS Code,
ignoring damping & embedment effect of soil. This
will make the foundation more expensive and

difficult to design. Thus he propose a method based
in which the number of such deficiencies as cited
above can be circumvented. Payal Mehta states that
dynamic load is not short lived but act over a large
period of time. Dynamic force which is generated
depend upon the machine type & its operation
mechanism & frequency. Rohit R Sharma, Prashant
V. Muley, Prashant R. Barbude state about the
machine which creates vibration on foundation. due
to which higher dynamic forces are generated. So
they suggest the designed aids / method for
foundation design. The ideas about the characteristics
of harmonic force stated by Cyril Harris in his book
"Harris' Shock and Vibrations" were proved to be
beneficial while making the mathematical model of
the looms machine. M. J. Pender gives a review
about the main issues in the design of shallow
foundation and deep foundation which may be
subjected to earthquake loading.
II. METHODOLOGY
The dynamic analysis of foundation for blower
type machine is done by following approach.
Reconnaissance Survey which includes visit to
the effluent treatment plants, industry and interaction
with the industry people for getting a better practical
picture of the blower type machine foundation, study
of structural system of the machine foundation in
industry and understanding the working of the blower
type machine.
Collection of necessary machine data such as the
dimension of the machine components, its operating
speed, frequency of motor and blower, RPM of motor
and blower, Mass of motor and blower etc. Also, the
data regarding the foundation which includes
dimensions of the block and pile have been collected.
Preparation of drawing of foundation plan
showing layout of machine position on the
foundation floor and pile dimensions in case of pile
model using CAD software.
Modelling of Machine Foundation Structure using
structural engineering software - STAAD.Pro has
been done. Its pre-analysis includes modelling,
labelling, assigning geometric properties and loads to
various structural components, as well as to assign
support conditions and to assign suitable analysis
commands. The post-analysis includes studying of
various modes shapes and their respective
frequencies amplitude and displacement.
Plotting of graphs of various results of frequency
and displacements with respect to two types of
machine foundation models has been done.
III. MACHINE DETAILS/DATA
Blower:-Blower is used in Effluent Treatment Plant
in industry for the purpose of treating water.
Types of blowers:
1. Horizontal blower
2. Vertical blower
There is some flexibility in the configuration of a
rotary blower in terms of the locations of gas
connections and drive shaft. Depending on the model,
the gas connections can be either on the top and
bottom of the unit, on the sides or a combination.
When the connections are on the top and bottom,
the unit is designated as a “Horizontal” machine and
when the connections are on the sides, it is a
“Vertical” machine. The designation has nothing to
do with the direction of gas flow but comes from the
orientation of the blower shafts, i.e., when a plane
intersecting the shafts is horizontal, the unit is so
designated. Conversely, when the plane is vertical,
the machine is designated as vertical. Some units can
have the inlet connection on the top and the discharge
on the side. Since a plane through the shafts
establishes the definition of the orientation, this
would be a “Horizontal” machine. This issue is
critical when designating the specifics of a blower as
some manufacturers define the orientation
differently.

VII. CONCLUSION
As far as X-direction displacement is concern,
Hollow Block Foundation with Piles shows good
performance as compare to Table Mounted Block
Foundation. From the Fig. 11 it is clearly visible that
Table Mounted Block Foundation has maximum
displacement in X-direction at top node and bottom
node than Hollow Block Foundation with Piles
because Table Mounted Block Foundation shows
more flexible behaviour structurally. From table 5, it
can be seen that frequency values are very less in
case of table mounted block foundation as compared
to hollow block foundation with piles. Hence,
displacement is more in case of table mounted block
foundation.
As far as Y-direction displacement is concern,
Hollow Block Foundation with piles is better in
performance as compare to Table Mounted Block
Foundation. The reason behind that is Hollow Block
Foundation with piles has piles below block
foundation which helps in preventing Y-direction
(vertical) displacement.
Hollow block foundation with piles shows a
great variation in frequency as compared to table
mounted block foundation. The variation in
frequency from mode 1 to mode 6 in case of hollow
block foundation with pile is about 496% and in case
of table mounted block foundation is 207%. The
hollow block foundation with pile is more stiff
foundation due to provision of pile below and hence
frequency is more.
Von Mises stresses are more in Hollow Block
Foundation with Piles as all the forces transferred by
machine to block is ultimately taken by piles and
hence, entire blocks foundation is in lower stress
zone. In table mounted block foundation, there exist
no piles hence all the loads are to be transmitted by
R.C.C walls and block foundation to the soil below
and hence values of von Mises stress contours is
more
