Traditional Machining Technology

Traditional Machining Technology describes the fundamentals, basic elements, and operations of general-purpose metal cutting and abrasive machine tools used for the production and grinding of cylindrical and flat surfaces by turning, drilling, and reaming; shaping and planing; and milling processes.

Special-purpose machines and operations used for thread cutting, gear cutting, and broaching processes are included along with semiautomatic, automatic, NC, and CNC machine tools; operations, tooling, mechanisms, accessories, jigs and fixtures, and machine-tool dynamometry are discussed. The treatment throughout the book is aimed at motivating and challenging the reader to explore technologies and economically viable solutions regarding the optimum selection of machining operations for a given task.

This book will be useful to professionals, students, and companies in the industrial, manufacturing, mechanical, materials, and production engineering fields.

Helmi Youssef, born in August, 1938 in Alexandria, Egypt, has acquired his B.Sc. degree with honor in Production Engineering from Alexandria University in 1960. He completed then his scientific building in the Carolo-Welhelmina, TH Braunschweig in Germany during the period 1961-1967. In June 1964 he acquired his Dipl.-Ing. degree, then in December 1967, he completed his Dr.-Ing. degree in the domain of Non-traditional Machining. In 1968, he has returned to Alexandria University, Production Engineering Dept. as an assistant professor. In 1973 he has been promoted to associate, and in 1978 to full Professor. In the period 1995-1998, Professor Youssef was the chairman of the Production Engineering Dept., Alexandria University. Since 1989, he was a member of the scientific committee for promotion of professors in Egyptian universities.

Based on several research and educational laboratories, which he has built, Professor Youssef founded his own scientific school in both Traditional and Non-traditional Machining Technologies. On early 1970s, he established the first NTM-research laboratory in Alexandria University, and may be in the whole region. Since that time, he carried out intensive research in his fields of specialization, and supervised many Ph.D. and M. Sc. theses.

Between 1975 and 1998, Professor Youssef was a visiting Professor in Arabic universities, such as El-Fateh University in Tripoli, the Technical University in Baghdad, King Saud University (KSU) in Riyadh, and Beirut Arab University (BAU) in Beirut. Beside his teaching activities in these universities, he established laboratories, and supervised many M.Sc. theses. Moreover, he was a visiting professor in different academic institutions in Egypt and abroad. During 1982, he was a visiting Professor in the University of Rostock, Germany, and during the years 1997 – 1998 he was a visiting Professor in the University of Bremen, Germany.

Professor Youssef has organized and participated in many international conferences. He has published many scientific papers in specialized journals. He authored many books in his fields of specialization, two of which are single authored. The first is in Arabic, titled Nontraditional Machining Processes, Theory and Practice, published in 2005, and the other is titled Machining of Stainless Steels and Superalloys, Traditional and Nontraditional Techniques, published by Wiley in 2016. Other two co-authored books are published by CRC in 2008 and 2011, respectively. The first is on Machining Technology, while the second deals with the Manufacturing Technology.

Currently, Professor Youssef is an emeritus Professor in PED, Alexandria University. His work in the time being involves developing courses and conducting research in the areas of metal cutting and nontraditional machining.

Hassan El-Hofy received his BSc in Production Engineering from Alexandria University (AU), Egypt in 1976 and his MSc in 1979. Following his MSc, he worked as an assistant lecturer in the same department. In October 1980 he left to Aberdeen University in Scotland, UK and began his PhD work with Professor J. McGeough in electrochemical discharge machining. He won the Overseas Research Student (ORS) award during the course of his doctoral degree, which he duly completed in 1985. He then returned to AU and resumed his work as an assistant professor. In 1990, he was promoted to the rank of an associate professor. He was on sabbatical as a visiting professor at Al-Fateh University in Tripoli between 1989 and 1994.

In July 1994, he returned back to AU, and was promoted to the rank of full professor in November 1997. From September 2000, he worked as a professor for Qatar University (QU). He chaired the accreditation committee for mechanical engineering program toward ABET Substantial Equivalency Recognition that has been granted to the College of Engineering programs (QU) in 2005. He received the Qatar University Award and a certificate of appreciation for his role in that event.

Professor El-Hofy wrote his first book entitled Advanced Machining Processes: Nontraditional and Hybrid Processes, which was published by McGraw Hill Co in 2005. The third edition of his second book entitled Fundamentals of Machining Processes―Conventional and Nonconventional Processes appeared in November 2018 by Taylor & Francis Group, CRC Press. He also coauthored the book entitled Machining Technology―Machine Tools and Operations, which was published by Taylor & Francis Group, CRC Press in 2008. In 2011, he released his fourth book entitled Manufacturing Technology―Materials, Processes, and Equipment, which again was published by Taylor & Francis Group, CRC Press. Professor El-Hofy has published over 80 scientific and technical papers and has supervised many graduate students in the area of advanced machining. He serves as a consulting editor to many international journals and is a regular participant in many international conferences.

Between August, 2007, and August 2010 he became the chairman of the Department of Production Engineering, AU. In October 2011 he was nominated as the Vice Dean for Education and Student’s affairs, college of Engineering AU. Between December 2012 and February 2018 he was the Dean of the Innovative Design Engineering (IDE) School at Egypt-Japan University of Science and Technology (E-JUST) in Alexandria, Egypt. He worked as an acting Vice President of Research from December 2014 to April 2017 at E-JUST. Currently he is the professor of machining technology at the Department of Industrial and Manufacturing Engineering (IME) at E-JUST.
