CE 1.2 Project Background
CE 1.2.1 Characteristics of the project
This project of Design and Analysis of Grinding Attachment was the Machine tool
Design project that I executed in the fourth year bachelor’s degree. The grinding operation in
a lathe machine is solely performed to obtain excellent surface finishing once the turning
operation is completed. This is eventually done to learn about the needed dimensions of
portion, which are to be used in the assemblies. Hence, to execute these two important and
significant operations on a lathe machine, the designing of grinding attachment is done. The
analysis part of this project is done to verify the project. This particular project discusses
regarding an attempt to decrease the total time for both loading as well as unloading of any
work piece with the preferred surface finish. The project gives a proper description regarding
the wheel selection for grinding. The grinding attachment of lathe machine also takes into
account the lack of flexibility within the design. This design is then subsequently analyzed on
inventor software and thus compared with several theoretical calculations.

CE 1.2.2 Objectives developed for the project
The project of Design and Analysis of Grinding Attachment has various significant
objectives. The objectives are as follows:
 To design as well as analyze the grinding attachment of a lathe machine.
 To execute various operations.
CE 1.2.3 My area of work
I was an important member in the project team for designing and analyzing grinding
attachment of a lathe machine. I ensured the fact that this project becomes successful. I had
significantly worked under the perfect supervision of my team leader and head of the
department. In the beginning, I had several doubts about the project. However, my team
members and team leader helped me to clear all my doubts and thus I was able to understand
the complete project perfectly. This project has even helped me in understanding the entire
concepts of grinding attachment as well as lathe machine. My major area of work was to
design the grinding attachment of the lathe machine.

CE 1.2.5 My responsibilities throughout the project
I had several significant responsibilities throughout the project. I was given the core
responsibility to create the design of the grinding attachment. Since this was my fourth year
Machine tool design project, I made sure that the design is made perfectly. Next, I checked
the various processes, which are to be executed in the project work. I subsequently
customized, examined and assessed the products. I even made the list of the raw materials,
required in this project. I kept a record of the data that were taken while calculating. I even
analyzed and interpreted the taken data to design and analyse the project. I also arranged for
project team meetings that were hold in the end of every week for understanding the strengths
and weaknesses of the project.

CE 1.3 Distinctive Activity
CE 1.3.1 Comprehending the Theory of the Project
The design indications of any grinding attachment mainly comprise of several
mechanical knowledge and functionalities for several equipments. The major equipments of
this project involve a motor, a grinding wheel, shafts, mounting plates, belt, bearings and
pulleys.
For achieving the objective, this project comprised of some of the significant facts
that would have been guaranteeing the accuracy of 20 microns. Three important facts were
identified. They were absorption of vibration, attachment rigidity and cylindricity of work
piece. For the vibration absorption, the static deflection was 0.0126m. There is a relation
between damping ratios and transmissibility. Several materials were taken into consideration.
The damping ratio in for the rubber was 0.05. Hence, we selected rubber as the isolator.
Materials Damping Ratio
Steel Spring 0.005
Rubber 0.05
Neoprene 0.05
Elastomers 0.12-0.15
Glass fiber pad 0.1-0.2
Composite Pad 0.3
Table 1: Damping Ratios of Isolators
The second fact was the rigidity of attachment. When the motor is working in higher
speed, it was extremely important to clamp that motor. The mathematical calculations of the
project were done by software analysis. The stress analysis result is given in the following
table.

Particular Minimum Maximum
Stress XX -0.0342MPa 0.0225MPa
Stress XY -0.0174MPa 0.0106MPa
Stress XZ -0.0130MPa 0.009MPa
Stress YY -0.027MPa 0.0271MPa
Stress YZ -0.0142MPa 0.0168MPa
Stress ZZ -0.0360MPa 0.0308MPa
Table 2: Stress Analysis Result
The cylindricity of the workpiece is assured for maintaining the circular cross section
area. The major factor that solely affected the cylindricity was the forces due to the grinding
would not bring perfect results. Hence, deflection of shaft was required.
CE 1.3.2 Engineering knowledge and skills applied in the project
I had utilized various mechanical engineering skills like 3D CAD and analytical
thinking in this project. I had even utilized other skills like automated model programming
and assembling project deliverables. The other skills that I had used in the Machine tool
design were conversion of basic design information as well as requirements into working
drawings and designing. Moreover, I knew how to create blueprints for the design purpose of
the project. I also drafted the standards and GD&T or Geometric. Dimension and
Tolerancing.
CE 1.3.3 Identified issues and their solutions
1.3.3.1 Issues
There were several mechanical problems or faults within the project of design and
analysis of grinding attachment of a lathe machine. The first and the foremost problem, which
I encountered in the project was while designing the wheel. I knew it very well that if the

wheel of this grinding attachment would not work perfectly, it is needless to say that the total
machine would be working and thus the user would not be able to utilize this machine. The
second important problem that we faced was the incorrect list of raw materials. One of my
team mates took the responsibility to make the list of the raw materials. However, he was
unable to do so and thus our project was getting delayed. The third significant issue that
occurred in the project was while the machine motor was designed. The total productivity of
the machine depends on this motor. Thus there should not be any mistake in the motor
designing.
1.3.3.2 Solutions
I was extremely happy and satisfied as I was able to solve all the problems of the
project with my skills and knowledge of engineering and power of critical thinking. The first
issue was with the wheel. I gave a suggestion to my team leader to use soft wheels instead of
hard. The hard wheels, although effective, increments the complexities; whereas the soft
wheels, although less effective, decrease the overall complexities. The next issue was with
the equipments selection. I checked and was able to find out the mistakes. I finally made the
new list of materials and thus the project was not delayed anymore. Finally, for the last issue,
all of the team members were under tight spot to design the motor perfectly. However, I came
forward and took the responsibility to design it. I utilized my engineering knowledge and
skills for solving the issue. I designed the motor perfectly and was appreciated by my team
leader.
CE 1.3.4 Plan to produce creative and innovative work
We made a plan to produce creative and innovative work by segregating our duties
and responsibilities. At first, we had vague ideas about the project, however, soon our doubts
were cleared and we were able to understand the project perfectly. Since, this was the final

year project; we all were extra conscious about it. We attended various workshops and team
meetings to produce better work and finally we were happy to do so with utmost perfection.
CE 1.3.5 Collaborative work
The complete project was executed in a specific sequence of all types of collaborative
actions amongst the team members and the team leader. Our major goal was to design and
analyze the project perfectly so that it could be utilized by the rest of the world. Our head of
the department controlled everything and each and every activity was reported to him by our
project leader.
