ADVANCED NONCONVENTIONAL MACHINING PROCESSES

The field of machining has evolved significantly over the past
few decades, moving beyond traditional methods to embrace
advanced non-conventional machining processes. These
processes, which include techniques such as abrasive jet
machining, water jet machining, ultrasonic machining, and laser
beam machining, among others, offer unique capabilities and
advantages that are crucial for modern manufacturing. The
purpose of this book, Advanced Non-Conventional Machining
Processes, is to provide a comprehensive overview of these
cutting-edge techniques, their applications, advantages,
limitations, and recent advancements.
Chapter 1 begins with an introduction to the mechanical
processes and provides a detailed classification of nontraditional machining processes. The subsequent sections delve
into various jet machining techniques, such as abrasive jet
machining (AJM) and water jet machining (WJM), outlining
their process characteristics, applications, and equipment. The
chapter also explores ultrasonic machining (USM) and recent
developments in the field, ensuring readers are up-to-date with
the latest innovations.
Chapter 2 focuses on chemical and electrochemical processes,
presenting an in-depth analysis of chemical milling,
photochemical machining (PCM), and electrochemical
machining (ECM). Each section highlights the processes’
characteristics, advantages, limitations, and specific
applications, providing a well-rounded understanding of these
techniques.
Chapter 3 examines thermo-electrical processes, including
electrical discharge machining (EDM), electron beam machining
(EBM), laser beam machining (LBM), and plasma arc cutting
(PAC). The detailed discussion covers the unique features,
benefits, and challenges of each process, as well as the types of
equipment used and their capabilities.
In Chapter 4, the book addresses modern nano finishing
techniques such as abrasive flow finishing (AFF), electrolytic inprocess dressing (ELID), magnetic abrasive finishing (MAF),
chemo-mechanical polishing, and magneto-rheological
finishing. These sections emphasize the working principles,
process variables, applications, and the advantages and
disadvantages of each technique.
Chapter 5 is dedicated to the latest advancements in nonconventional machining processes. It explores current
developments, breakthroughs in technology, environmental
considerations, digital manufacturing integration, and the future
of these processes. Special attention is given to novel
advancements in EDM, updates on wire cut EDM technology,
machining of super alloys and stainless steels, and the
machinability of composites. Additionally, vibration-assisted
machining techniques are discussed in detail.
This book aims to serve as a valuable resource for engineers,
researchers, and students involved in the field of machining. It
offers a thorough understanding of advanced non-conventional
machining processes, equipping readers with the knowledge
needed to implement these techniques effectively in their
respective domains. Through this comprehensive guide, we hope
to contribute to the ongoing advancement and innovation in the
field of manufacturing.
