Abrasive Water Jet Machining Of Engineering Materials

This book presents insights in green techniques used in conventional and advanced machining. It consists of various experimental case studies conducted by the authors on green machining of difficult-to-machine materials, polymer and ceramic materials. Effects of green techniques / processes on machining properties like material removal rate, surface quality, geometric accuracy, productivity, and environment while machining various materials are reported.

Manufacturing industry is becoming ever more time-conscious with regard to the global economy, and the need for rapid prototyping and small production batches is increasing. These trends have placed a premium on the use of new and advanced technologies for quickly turning raw materials into usable goods; with no time being required for tooling. The need for advanced processing technologies is particularly evident when machining advanced materials, such as ceramics, composites and thermo-sensitive materials that have wide application but are considered to be "difficult-to-machine" using conventional machining technologies such as turning and milling. Abrasive waterjet (AWJ) machining has been found to be one of the advanced technologies that meet these processing requirements; due to its distinct advantages over other machining technologies.

This volume contains papers presented at the 11th International Conference on Jet Cutting Technology, held at St. Andrews, Scotland, on 8-10 September 1992. Jetting techniques have been successfully applied for many years in the field of cleaning and descaling. Today, however, jet cutting is used in operations as diverse as removing cancerous growths from the human body, decommissioning sunsea installations and disabling explosive munitions. The diversity is reflected in the papers presented at the conference. The papers were divided into several main sections: jetting basics -- materials; jetting basics -- fluid mechanics; mining and quarrying; civil engineering; new developments; petrochem; cleaning and surface treatment; and manufacturing. The high quality of papers presented at the conference has further reinforced its position as the premier event in the field. The volume will be of interest to researchers, developers and manufacturers of systems, equipment users and contractors.

Abrasive water jet machining was introduced to manufacturing ten years ago and has been increasingly used for treating hard-to-machine and multi-layered materials and as an alternative tool for milling, turning, drilling and polishing. This is the first comprehensive review of the technique, dealing with a broad range of issues including mixing and acceleration processes, material removal mechanisms, process optimization and fluid mechanics. Explanations are given as the book follows the development of an abrasive water jet machining process, from tool generation through to machining results, supervision and control. This methodical journey through the field is marked by drawings, graphs and tables, many of which are being published here for the first time. Though the book is written at an academic level, it focuses very much on practical applications, which reflects the authors' extensive involvement with both laboratory research and industrial practices.

The subject matter of this book is the information on the abrasive technology methods, the characteristics of the methods (for example, the technological parameters, tools, and machines), innovative methods, characteristics of surface structure and surface properties after this type of mechanical process, and application in various industrial branches and other technical and technological domains. Abrasive technology is very important, for example, in precision component manufacturing and nano-technology devices. The aim of this book is to present information on the characteristics and applications of abrasive technology, abrasive tools, tests, and also the innovative methods of this technology. This information enables scientists, engineers, and designers to ensure the soundness and integrity of the fabricated components and to develop new techniques effectively.

This text should be useful to both researchers and postgraduates or final-year undergraduates who are specializing in manufacturing processes. It should also be useful to those industrial users of materials processing who are charged with making abrasive waterjet machining more efficient.

This book explores new possibilities in the domain of abrasive waterjet machining (AWJM) of composites and polymers. AWJM is a sustainable and well industrialized process, but some parameters of AWJM process need to be optimized according to new composites materials and polymers to obtain the desired machining characteristics. This book presents the reader with the state of the art methodology to cut the advanced composite materials.

This excellent volume will serve as an indispensable reference and source book for process design, tool and production engineers in composite manufacturing. It provides the reader with a comprehensive treatment of the theory of machining as it applies to fiber reinforced polymer composites. It covers the latest technical advances in the area of machining and tooling, and discusses the applications of fiber reinforced polymer composites in the aircraft and automotive industries.
