CD Cutting CNC Machine Project - Mechatronics Engineering

Career Episode 2
(CD cutting CNC machine)
Introduction:
Career Episode 2.1:
I did my bachelor’s in Mechatronics Engineering from one of the oldest and prestigious
universities in Egypt known as Ain Shams University. Mechatronics Engineering has been
included in the curriculum in 2004 and I graduated with Mechatronics degree being the third
alumni of the university. Our final semester project was CD cutting CNC machine and it took 6
months to complete the project from January 2008 to June 2008.
Background:
Career Episode 2.2:
I was asked to choose a topic for our final year project that would require knowledge gained in
our 5 years of engineering. The professor asked us to divide into groups of 4-5 students and
choose a topic of project that would require implementing knowledge gained and presenting the
project before a panel of professors who would give grades to our project. The project consisted
of the following subparts:
 Milling machine mechanical design
 Selection of the construction material
 Milling machine manufacturing
 Coding, circuit design, block diagram

 Trouble shooting and testing
Career Episode 2.3:
The topic chosen was for graduation project in Ain Shams University. The prerequisites for
graduating was finalising the objectives. As a team member I designed the CNC CD cutting
machine that will be able to cut a CD according to the AutoCAD design. The information is
communicated through coded software developed. There are some advantages of CNC CD
cutting machine like CD design can be printed on real CD by implementing it on AutoCAD. The
design can be used for marketing and advertising purposes. Additionally, the machine can be
used in 3D printing if it can be adjusted from 2D to 3D.
Career Episode 2.4:
Dr. Farid Abdel Aziz Tollbah supervised our project. He was the referred to as computerized
numerical Control professor. The project leader of the project was Hani Amin and my team
members were Nader Adeeb, Mina Sameh and Amir Wahib.

Activities involving creation of the project:
Career Episode 2.5:
I was selected as the co-leader and I helped in designing CNC machine using AutoCAD, selected
materials for different parts of the machine, did manufacturing of different parts, and done
machine performance testing and assembling various parts of the machine. As a part of the team,
I performed the following tasks:
 CNC machine designing in AutoCAD
 Material selection for several moving parts of the machine
 Understand dimensions of the project is necessary to demonstrate design capabilities and
technical knowledge. This helped in ensuring the quality of design
 Ensured teamwork capacity by working in a team
 Did the cost analysis to ensure that the manufacturing and design of the machine is done
within the budget set before
 Selection of workshops and research to manufacture different parts
 Assembling the machine
 Performed testing of the machine and
 Presented the project before the professors
