Had to keep the developed model flexible enough to be operated same as that of the
expectations. I had to analyze the sensitive sectors of the drill machine and modify the existing
models in manner to make sure that enough flexibility is being introduced to meet the objectives
of the project. I managed to manipulate the radial arm and allow drill machine to be operated
withint he 360 degree. I embedded the following movements in the machine:

 Horizontal arm’s Up & down movement on vertical arm
 Rotation of arm joint up to 360 degrees
 Horizontal arm’s Linear slide movement
CE 2.2.4 Project Group
CE 2.2.5 My responsibilities throughout the project
I was responsible for the accomplishment of the operational activities by the team
members and assuring that the activities being delivered is capable of meeting the objectives of
the project. I had to develop the sophisticated model of the newly proposed drilling machine in
manner to assure that it is of same capability and assuring that is much efficient and effective

than previous models. I assured that the setup procedure is being accomplished in an efficient
manner through assigning three team members with three different jobs including modification
in the base, arm, and cross slide. I managed the budget of the proposed drill machine to be cost
effective through using the components of low budget those were not altering the ultimate output
of the project.
CE 2.3 Distinctive Activity
CE 2.3.1 Comprehending the theory of the project
The basic operation of a drill machine is to drill holes on certain work pieces through
using a drill. The machine was developed to reduce the human effort and deliver the drills in an
efficient and effective manner. However, more efforts can be driven for manipulating the
existing models and developing a more sophisticated model that can be utilized in much better
and efficient manner. This is one of the simplest model of the machine however, implementing
little complications in the arm, base, and cross slides in manner to allow the user to drill at
different locations in much better and reduced effort ways. The flexibility has been implemented
within the drill machine that can be applicable in sliding horizontally and vertically through
mounting the entire head on the radial arm.
CE 2.3.2 Engineering knowledge and skills applied in the project
I had to set up the entire drill system and thus, set up the base, arm, and cross slides as
per the proposed design. I used mild steel as the base of the driller that was supporting the
physical weight of the drill machine. I managed to restrict the vibration effects through limiting
them to the extent level. I implemented two arms including horizontal and vertical arms as the
primary and secondary arms for executing the necessary operations. These offered modifications

allowed the driller to drill in 360 degree movements through moving the drill head at the angles.
For the cross slides, I used a hand drilling machine as it was fixed on the cross slide and the
proposed drill machine is capable of drilling on the concrete, metal and woods. I kept the design
effective in manner to be applicable in clockwise and anti-clockwise directions. I used the
following components for the development of this project:
Motor
Connecting rod
Pulleys
Bearing
Screws
Drill bit
Following are the specifications of the components that I had been used in this project:

CE 2.3.3 Identified issues and their solutions
2.3.3.1 Issues
I identified that the drill machine was not functioning in 360 degree as it was being stuck
at some of the cuts in the device allowing movements in the drill. The size of the drill machine
was being bigger than the expectation due to the bases and two drilling arms that was leading
away from the objectives. The team was not acting as a collaborative team as everyone was
thinking differently and acting accordingly and so, this would have possibly influence the entire
production and output of the project.
2.3.3.2 Solutions
I applied glycerine and oil at the rotating parts in manner to reduce the resistance and
allow smooth rotating of the devices. I managed to implement the small parts for the entire
system made of hard alloys in manner to be compact in size. I developed a communication plan
through introducing meeting strategies after every week where, everyone was allowed to speak
freely related to the project or personal development and growth. This helped in creating a
bonding among the team members and allowing them to understand each other.
CE 2.3.4 Plan to produce creative and innovative work
I developed a model of the drill machine that was capable of drilling in 360 degree that
was an innovative approach in the field of the industries and assuring the enhancement in its
applications within the industries. I introduced two arms in manner to establish mobility within
the drill machine to drill at different locations and allow the flexibility of drilling in 360 degree. I
used mild steel for the base of the driller in manner to metal some weight and make it strong
enough to be applicable for drilling in the wooden piece and metal.

CE 2.3.5 Collaborative work
Every team member had contributed in the growth and development of the project and
contributed in the development of the sophisticated model that can be utilized by the industries. I
was managing the roles and responsibilities of the team members and thus, continuously
motivated them towards accomplishing the objectives and goals of the project. The developed
communication plan was effective enough to make a bond in between the team members and
assuring that everyone understands each other thought and perspectives on the respective
operations.

CE 2.4.1 Project Overview
I proposed the project that will allow the modifications in the existing drill machines in
manner to enhance the operations and effectiveness of the drilling systems. The project was
developed successful and was applicable same as it was expected in manner to allow the drill to
be made on the working piece in 360 degrees. I managed to develop the model of the drill
machine that would cost 40,000 INR irrespective of the price of the drill machine at that time (1,
50,000 INR). I managed the team members and continuous monitor them that lead to the
delivery of every sector of the job within the project in much efficient and effective manner.
