COURSE SYNOPSIS
This course enables the students to comprehend and identify theoretical design as well as the machine elements that need to be considered in machine design process.
This course also encourages the students to think as a machine designer.
The concept and principle of machine design will be applied in designing machine, focusing on the outcome of innovative student thinking.
Dr. Marwan Affandi 2010
COURSE SYNOPSIS
The course starts with the principle of basic
design concept and design phases.
It concentrates on the dynamics of machine
design, as required in mechatronic program.
The basic element of dynamics will be
reviewed, such as kinematics, machine
mechanism, velocity and acceleration
analysis.
Dr. Marwan Affandi 2010
COURSE SYNOPSIS
The components of machine design will
include gear systems, power screws, belts,
chain drive, cams, shafts, springs and
bearings.
Students will be exposed to the laboratory
work using MATLAB; other software such
as Mdesign may be used.
Students are required to provide a technical
report on engineering product or to develop
a product design.

Dr. Marwan Affandi 2010
EVALUATION CONTRIBUTION
There will be four (4) assignments given, either
individual or group.
Students must submit their assignments on the
stipulated date. Late submission will result in the
deduction of the mark from 10% to 100%!
If a student cannot submit an assignment due to
any reason on the stipulated date, he or she must
submit it before the date. He or she can submit the
assignment through his or her friend.
Dr. Marwan Affandi 2010
EVALUATION CONTRIBUTION
There will be also four (4) tests given. Students
who do not submit their test papers are considered
to be absent from the class at the date of the test.
Assignments and tests which have been marked
will be returned to the students on the stipulated
date.
If the assignments or the tests are not returned by
the lecturer on the stipulated date, the students
will get 80% of the full marks for the assignments
or the tests.

Any question?
If you have questions, you had better ask me now.
The longer you keep it in your head, the less you
will understand later.
If you are shy to ask any question in this class, you
can ask me later.
You can also come to see me directly in my room.
But please make an appointment first.
If you like, you can ask me through email or phone
me. But please don’t send me sms.
