Machining and machine-tools Research and development EDITED BY J. PAULO DAVIM.
Machining and machine-tools is an important subject with application in several industries. Parts manufactured by other processes often require further machining operations before the final product is made. Traditional machining is the broad term used to describe removal of material from a workpiece, and covers chip formation operations – turning, milling, drilling and grinding, for example. Recently, the industrial utilization of non-traditional machining processes such as EDM (electrical discharge machining), ECM (electrochemical machining) and USM (ultrasonic machining) has increased. Also, the performance characteristics of machine-tools and the significant development of existing and new processes and machines need to be considered. In Europe, the USA, Japan and countries of emerging economies machine-tools is a sector undergoing great technological evolution. Machining processes can be applied to work metallic materials, polymers, wood, ceramics, composites, biomaterials, nanomaterials and other specialist materials.
This book aims to provide information on machining and machine-tools for modern industry. Chapter 1 provides an analysis of the evolution of acoustic emission signals for monitoring diamond-coated tool delamination wear in machining. Chapter 2 is dedicated to high-performance machining of austenitic stainless steels.
Chapter 2 presents an analysis of forces monitoring in shape grinding processing of complex parts. Chapter 4 covers optimization of minimum quantity lubrication in grinding with CBN (cubic boron nitride) wheels. Chapter 5 is dedicated to EDM, in particular a study on machining characteristics of WC-Co composites.
Chapter 6 provides information on conventional and unconventional hole making in metal matrix composites (MMCs). Chapter 7 describes a laboratory machine for microelectrochemical machining. Finally, Chapter 8 is dedicated to a cam-driven electromagnetic mechanical testing machine.
The book can be used as a research tool for a final undergraduate engineering course or as a topic on machining and machine-tools at the postgraduate level. It can also serve as a useful reference for academics, manufacturing researchers, mechanical, manufacturing, industrial and materials engineers, and professionals in machining and related industries.
Traditional machining is the broad term used to describe removal of material from a work piece, and covers chip formation operations including: turning, milling, drilling and grinding. Recently the industrial utilization of non-traditional machining processes such as EDM (electrical discharge machining), LBM (laser-beam machining), AWJM (abrasive water jet machining) and USM (ultrasonic machining) has increased. The performance characteristics of machine tools and the significant development of existing and new processes, and machines, are considered. Nowadays, in Europe, USA, Japan and countries with emerging economies machine tools is a sector with great technological evolution.
