CE 3.2 Project Background
CE 3.2.1 Characteristics of the project
Grinding operation is performed for obtaining an excellent surface finish after performing
the turning operation on a specific lathe machine for any type of cylindrical jobs. This is done for
obtaining the required dimensions of the portion that is to be utilized in any particular assembly.
Therefore, for performing these two specific operations on the same perfect machine the grinding
attachment is designed. Fabrication of this grinding attachment is done for verification. This
project describes about an attempt for decreasing the overall time in the loading and the
unloading of a particular work piece with desired surface finish. This project provides a
description about the selection of wheel for the purpose of grinding. The project of grinding
attachment even considers the inflexibility of the design, damping of trembling due to the speed
of the motor and stress analysis of the critical part of the design. This design is analyzed on the
inventor software and compared with all types of theoretical calculations.

CE 3.2.2 Objectives developed for the project
The design and fabrication of project of Design and Fabrication of Grinding Attachment
has some of the major and significant objectives. The objectives developed for this particular
project are as follows:
 To design and fabricate a Grinding Attachment of lathe machine.
 To perform several operations
 To grind small jobs.
 To help the small and medium enterprises.
CE 3.2.3 My area of work
I was a member of the project team of grinding attachment of lathe machine. I made sure
that the project was successful. I had worked under the supervision of my team leader and head
of the department. My team leader distributed the entire work amongst us equally. At first, I had
few doubts for the project. However, under the supervision of the head of the department and
team leader, all my doubts were cleared and I understood the entire project perfectly. This
project helped me to understand the concept of grinding attachment and lathe machine
completely and easily. I have utilized my mechanical engineering skills and knowledge for the
successful completion of the project.

CE 3.2.5 My responsibilities throughout the project
I had undertaken significant research on the project study. I had implemented the project
design and fabrication of the grinding attachment of lathe machine. Then, I had checked the
processes that are needed for this particular project work. I had customized, tested, assessed as
well as again tested these particular products. My major responsibility was the writing part of the
project reports and also documenting the most important data into the report. I had even
interpreted and analyzed the project data for designing and fabricating of the main project. My
involvement in the project was from designing until the completion of the work. I made sure that
the project study was done perfectly.

CE 3.3 Distinctive Activity
CE 3.3.1 Comprehending the Theory of the Project
The design reflections of the grinding attachment of lathe machine consist of mainly
mechanical functions and knowledge for the specific equipments, although the importance is
equal. These typical design reflections consist of the characteristics that are technical for both
major and the assisting selection of all the equipments and also the installation of the concerns
for those operations that are dependable. There is an important and significant need for the
grinding attachment of lathe machine as it is provided for the several operations.
The main equipments of the project include Motor, grinding wheel, mounting plate,
shafts, bearings, pulleys and belt. The basic components of a cylindrical grinder include a wheel
head, which incorporate the spindle and drive motor, a cross slide, that moves the wheel head to
end from the work piece, a head stock, which locates, holds, and drives the work piece, and a
tailstock, which holds the other end of the work. Grinding is the process of removing metal by
the application of abrasives, which are bonded to form a rotating wheel when the moving
abrasive particles contact the work piece, they act as tiny cutting tools, each particle cutting a
tiny chip from the work piece. In cylindrical grinding, the work piece rotates about a fixed axis
and the surfaces machined are concentric to that axis of rotation.
CE 3.3.2 Engineering knowledge and skills applied in the project
The main short coming that I had was the problem solving skills. Most of the time, I was
unable to solve the situational problems occurred during the design and fabrication. However, I
was successful in utilizing my mechanical engineering skills and knowledge and solved those

problems. Moreover, my ability for critical thinking was the major benefit for the project. I was
able to think out of the box and design and document the project study easily.
CE 3.3.3 Identified issues and their solutions
3.3.3.1 Issues
There were various mechanical faults or problems in the design and fabrication of the
grinding attachment of lathe machine. These problems were stopping the machine to be
successful. The main problem that was occurring was during the design of the wheel. This was
the most important part of the entire project. If the wheel of the grinding attachment of lathe
machine will not work properly, the entire machine will not work and the user will not be able to
use the machine. The second problem that occurred was the wrong selection of the equipments.
The team member, who was responsible for the perfect selection of the equipments, made a
completely wrong list and the entire project was at stake. The third problem occurred while
designing the motor of the machine. The motor of the lathe machine is responsible for the overall
productivity. If this motor will not be designed properly, it is evident that the entire machine will
not be set up and will not work.
3.3.3.2 Solutions
I was happy as I was able to solve all the problems of the project with my skills of
mechanical engineering and critical thinking. The first problem was with wheel. I gave the idea
to my supervisor for utilizing soft wheels. Hard wheels increases the complexities and the soft
wheels reduces these complexities. The second problem was the proper selection of the
equipments. I made sure that the entire list was made again and it does not create any further
problem. This helped to reduce the problems of the project easily. The third problem was a bit

tricky. The motor was the most important part of the project and all of us was under dilemma for
designing the perfect motor. I had the knowledge of core mechanical engineering. I utilized my
skills in solving this problem. I re designed the motor and thus the problem was solved. These
solutions helped me to understand that I have problem solving skills and I can utilize them in all
aspects.
CE 3.3.4 Plan to produce creative and innovative work
We made a plan to produce creative and innovative work by simply applying mechanical
skills and knowledge. In order to provide a smooth surface on rotors, such as brake drums, brake
discs, clutch plates and fly wheels, it is desirable to finish grinding the brake surface to level off
any hard spots in the rotor. Cylindrical grinding attachment is defined as having four essential
actions. The work must be constantly rotating. The grinding wheel must be constantly rotating.
This was our plan.
CE 3.3.5 Collaborative work
The entire project was conducted through a series of collaborative activities among the
rest of the team mates and me. I assisted my team leader with my fellow team mates in the
project right from the designing part. I was responsible for the documentation and recording of
the project reports. Everything was under the control of the head of the department.
CE 3.4 Project Review
CE 3.4.1 Project Overview
The grinding wheel is fed towards and away from the work, Either the work or the
grinding wheel is traversed with the respect to the other. The attachment can be fixed on a lathe
with or without tailstock. The abrasive material is on a grinding wheel that rotates in a direction

such that rolling or sliding contact occurs where the in wheel and work piece touch. This project
of grinding attachment of lathe machine has even reduced the effort of the human beings. We
made this project for the betterment of the world.
CE 3.4.2 My contribution to work
I was responsible for the documentation of the project reports. I even made the design of
the grinding attachment of lathe machine. I had composed with the project administration group
to clear up if there were any type of complexities in regards to the project work. At last, with a
specific end goal to set up the last project report, I had gone to project gatherings and given
introductions on the project to the project supervisor.
