ABSTRACT

Design and fabricating the mini milling machine is a conceptual

understanding of mechanical engineering.

With the on-going development of technology and economy, new industrial

requirements such as high precision, good quality, high production rates and

low production costs are increasingly demanded. Most of such requirements,

including dimensional accuracy, conformance to tolerances of finished

products and production rate can be met with better machine tools such as

mini milling machine with multiple functions on either face mill or drill.

The purpose of this project is to design and fabricate a mini milling machine.

Material that is strong and could withstand the weight and the vibration of

moving parts of the machine. Tests have been done to ensure the mini

milling machine has meet the objective stated.

The progress of this project needs documenting, as it can be a reference for

the next student who will make this project as well as for a research related

to the mini milling machine.

ACKNOWLEDGEMENTS

We would like to express our gratitude and appreciation to all those who gave us the

possibility to complete the project. A special thanks to our project supervisor,

PROF.AHMED GAAFAR. , we are very grateful for the encouragement, guidance,

stimulating suggestions and assistance that he accorded us from the beginning of the

project to its successful completion.

A special thanks with much appreciation the crucial role of the metal cutting & forming

work shop staff, who gave the permission to use all required machinery and the necessary

material and tools that we need to complete the project parts.

Last but not least, many thanks go to The Dean PROF.TAREQ ABD EL MALAK,

PROF. EL AWADY ATTIA the head of Mechanical department, and all people whose

have given their full effort in guiding the team in achieving the goal as well as their

encouragement to maintain our progress in track. I would to appreciate the guidance

given by other supervisor as well as the panels especially in our project presentation that

has improved our presentation skills by their comment and tips.
