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 creative and innovative student

thinking.


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 of machinery, velocity and

acceleration analysis.

The components of machine design will include

gear systems, power screws, belts and chain

drive; cams, shafts, and bearings maybe added.


COURSE SYNOPSIS

Introduction to robotics may also be added so this

course wil be useful for robotics courses later.

Students will be exposed to the laboratory work

and research using MATLAB; other software may

be introduced.

Students are required to provide a technical report

on selected engineering products or to develop a

product design.

Class activities will be conducted to

enhance students’ skills and knowleges.


COURSE CONTENT

1) Introduction To Design Process

2) Introduction To Mechanisms And Kinematics

3) Position and Displacement Analysis

4) Mechanism Design

5) Velocity And Acceleration Analysis

6) Gear Kinematics And Gear Selection

7) Kinematics of Belts, Chain Drives and Screw

Mechanisms

8) Cam Design (optional)

9) Introduction to robotics (optional)


LIST OF EXPERIMENTS

1) Position Analysis

2) Velocity Analysis

3) Acceleration Analysis

4) Linkage Synthesis


LEARNING APPROACH

Lecture : 48 Hours (75%)

Practical : 8 Hours (12.5%)

Tutorials : 8 Hours (12.5%)

Students are required to follow all lectures and tutorials given in the class, conduct all experiments in the lab, and do all quizzes, tests, and assignments.

There should be two-way communications between the lecture and the students.



EVALUATION CONTRIBUTION

Final examination: 60%.

Mid test: 10%

Course work: 30%.

Course work contribution:

Practical work: 15%

Assignments/Daily Tests : 10%

Project: 5%

If there is no project, Assignments/Dayly tests will

be 15%



There will be three (3) 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.

There is no reason for not submitting assignments.



There will be three (3) 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.

TEACHING PLAN

WEEK 16:

MINGGU ULANGKAJI / REVISION WEEK

• Time to refresh your memory about what you have

done so far!

• Remember, this is not the time where you start to

learn your subject before your final exam! It will be

quite late!

• You should study hard from the first week!

Otherwise you may cry because you cannot solve

the final exam questions!



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.


Don’t Worry, Be Happy!

It is not work that kills men; it is

worry.

Worry is rust upon blade.

Henry Ward Beecher


Dare To Dream

You see things; and you say

“Why?”

But I dream things that never were;

and I say “Why not?”

George Bernard Shaw
