Baba Amravati University, Amravati, Maharashtra, India
ABSTRACT
The study was based on design of experiment using Taguchi Orthogonal Array with three
parameters namely height of sewing machine table, angular movement of sewing machine
table and sliding movement of sewing machine table considered for experimentation. An
orthogonal Array of L9 experimental design was adopted & 3 angles namely trunk angle,
head angle and neck angle was measured for each experimental run. Then the reading for
female & male operator was separated & the qualitative analysis has been done on the basis
of operator’s opinion. From this qualitative analysis the optimize position for sewing
machine operator has been determined so that operators can work longer without any stress
or fatigue at back.(i.e. Risk of musculoskeletal disorder would be lower).
Keywords: sewing machine, taguchi method, ergonomics, musculoskeletal disorder.
INTRODUCTION
Today, corporate work spaces are
ergonomically designed, which simply
means body friendly. Millions of dollars
are spent each year on repetitive motion
injuries, forcing companies to address the
comfort and health of their workers.
Ergonomics are very important when it
comes to sewing since poor posture and
awkward positions will result in early
fatigue and pain in the neck, shoulders,
and back. The purpose of this project was
to look at conditions in the clothing
industry to find out how these injuries start
and how they can be prevented.
Researchers identified many features in
clothing plants that could be improved to
prevent injuries including:
The project’s final report brings together
all of the information gained from this
research. This report focuses on the
potential ergonomic problems and
solutions that were identified in plant. We
hope this report can be used to initiate
changes in the workplace by creating a
starting point for discussion and
stimulating ideas on how conditions in our
plants can be improved.
What Is “Ergonomics”?
Ergonomics is a topic that affects us all;
yet few of us have a good understanding of
what the term actually means or realize
how it affects us. Ergonomics is a science
that focuses on designing a job for the
worker. An ergonomically designed job
would ensure that a taller worker had
enough space to safely perform his or her
job and also that a shorter worker could
reach all of his or her tools and products
without reaching beyond a comfortable
and safe range. The opposite to this, and
what typically happens in the workplace, is
that a worker is forced to work within the
confines of the job or workstation that is

ABSTRACT
This paper tries to evaluate the OEE of machines in a valve manufacturing and identifies the
main loss elements of the process. An application had been created for continuous data
collection. OEE data on machine performance is an initial key point to understand the
equipment losses and establish improvement to eliminate them. The results are compared
with world class level. Result of the research demonstrates that although the OEE coefficient
of the investigated process is not meeting the world class level, however with the continuous
improvement, performance of the machine can be acceptable.
Keywords: lean manufacturing, overall equipment effectiveness, spread sheet
INTRODUCTION
OEE is an effective tool to benchmark,
analyze, and improve your production
process. The OEE tool gives you the
ability to measure your machines for
productivity improvements. OEE not only
measures these inefficiencies but groups
them into three categories to help you
analyze the machine and have a better
understanding of the manufacturing
process.
Here is a list of common concerns of many
manufacturing companies:
 Reducing Bottlenecks – Increase
Throughput
 Implementing Machine Operator
Training
 Reducing Machine Setup Time
 Improving Machine Reliability –
Implement Preventive Maintenance
 Maximizing Optimal Run Rates and
Capacity
 Eliminating Down Time – Provide
Down Time Reason Codes.
Putting this tool in place to address these
concerns and improve the manufacturing
process can be very time consuming and
costly. To reduce that cost, Overall
Equipment Effectiveness (OEE) Spread
sheet has been designed that is used to
help with this process. The spread sheet
allows the whole plant to be involved in
the process of improving OEE. From the
machine operator, production manager to
the plant manager, this production
monitoring information can help everyone
to come to a solution. The bottom line for
all employees should be to reduce
production losses and build profitable
products. The spread sheet provides
production managers and machine
operators with the necessary real time
information to make crucial decisions
about the effectiveness of the production
process.
Need for Analysis
The company is facing a low production
rate and high lead time in comparison to
its competitors. Estimation shows that

University, Chennai, India
ABSTRACT
Air compressor is designed to compress air to higher pressure and harness this potential
energy source and is powered by an air engine and stored in a tank. Compressed air or
pneumatic device is therefore characterized by a high power-to-weight or power-to-volume
ratio. Instead of mixing fuel with air and burning it in the engine to drive pistons with hot
expanding gases, compressed air vehicles (CAV) use the expansion of compressed air to
drive their pistons.
Keywords: compressed air technology, cost estimation, tool
INTRODUCTION
A compressed-air vehicle (CAV) is
powered by an air engine, using
compressed air, which is stored in a tank.
Instead of mixing fuel with air and burning
it in the engine to drive pistons with hot
expanding gases, CAV use the expansion
of compressed air to drive their pistons.
One manufacturer claims to have designed
an engine that is 90 percent efficient.[1–5]
Compressed air propulsion may also be
incorporated in hybrid systems, e.g.,
battery electric propulsion and fuel tanks
to recharge the batteries. This kind of
system is called hybrid-pneumatic electric
propulsion. Additionally, regenerative
braking can also be used in conjunction
with this system.[6,7]

Electrical Discharge Machining in Modern Manufacturing
Applications
Priyanka Garg*
University of Madras, Tamil Nadu, India
ABSTRACT
Several types of non-traditional machining processes have been developed to meet extra
required machining conditions. When these processes are employed properly, they offer
many advantages over non-traditional machining processes. Electrical Discharge Machining
is the most widely accepted non-conventional process in the manufacturing industry.
Keywords: aerospace industry, dielectric fluids, electrical discharge machining, non-
traditional machining process
INTRODUCTION
Electrical discharge machining (EDM) is
one of the most widely used non-
traditional machining processes. The main
attraction of EDM over traditional
machining processes such as metal cutting
using different tools and grinding is that
this technique utilizes thermoelectric
process to erode undesired materials from
the workpiece by a series of discrete
electrical sparks between the workpiece
and the electrode. A picture of EDM
machine in operation is shown in Figure
1.[1–4]
The traditional machining processes rely
on harder tool or abrasive material to
remove the softer material whereas non-
traditional machining processes such as
EDM uses electrical spark or thermal
energy to erode unwanted material in order
to create desired shape. So, the hardness of
the material is no longer a dominating
factor for EDM process. A schematic of an
EDM process is shown in Figure 2, where
the tool and the workpiece are immersed in
a dielectric fluid.

Manufacturing Process Involved in Development of Medical
Devices
S. Sharmila*
University of Madras, Chennai, India
ABSTRACT
The trend in medical device design and manufacturing is toward smaller, more portable
products that require more advanced components, manufacturing technologies and
automation techniques. Medical products covering the range of patient monitors, drug
delivery systems, therapeutic devices, and life assist devices all are shrinking in size while
increasing in performance and features. The present article describes about quality
improvement methods applied in manufacturing of medical devices.
Keywords: drug delivery, lean manufacturing, medical device, packaging, sterilization
INTRODUCTION
Medical device manufacturing includes all
aspects of the fabrication of a medical
device, from designing a manufacturing
process to scale-up to ongoing process
improvements. It also includes the
sterilization and packaging of a device for
shipment. Medical devices play an
important role in the field of medical and
health technology, and encompass a wide
range of health care products. Many
studies specify a medical device as any
instrument, apparatus, appliance, software,
material or other article, whether used
alone or in combination, including the
software intended by its manufacturer to
be used specifically for diagnostic and/or
therapeutic purposes and necessary for its
proper application, intended by the
manufacturer to be used for human beings.
The design and manufacture of medical
devices brings together a range of articles
and case studies dealing with medical
device R&D.[1]
LEAN CONCEPT FOR
QUALITATIVE MANUFACTURING
OF MEDICAL DEVICES
Throughout the manufacturing process,
medical device makers strive to be faster
and more efficient, but they also wish to be
responsible corporate citizens. Thus,
manufacturing demands constant insight
into renewable resources, sustainable
materials, equipment that is more energy
efficient, and methods to reduce waste
creation. Solutions to these issues can
come in the form of improved processes,
technological advances in machines or
equipment components, or safer/more
reliable materials. The same principles
apply to the packaging process. Many
companies call these ideals ‘lean’
manufacturing, which is considered an
industry best practice: eliminating any
activity, process, or material that does not
add value for which a customer will pay.
Still, while speed and cost-savings are vital
to successful manufacturing, quality
control is of the utmost importance –
particularly as medical device market
