Machinability of Advanced Materials
Publication Date: January 2014 Hardback 256 pp.
The term machinability refers to the relative ease with which a given material can be machined, using appropriate tooling and cutting parameters. Currently, several criteria are used to evaluate machinability, the most important of which are tool life or tool wear rate, cutting forces or power consumption, surface integrity, limiting rate of metal removal, and chip shape. In general, the factors that typically improve the material’s performance degrade its machinability. Therefore, machinability is affected by the properties of the workpiece material, tool material, machine tool, fixture, cutting fluid and cutting parameters. Machinability can be difficult to predict because it has so many variables. For this reason, an improvement in the technical ability to predict machinability is very important for modern manufacturing industries.
This book presents a collection of examples illustrating the state of the art and research developments in the machinability of advanced materials. Chapter 1 presents the concept of machinability. Chapter 2 covers milling burr formation and avoidance. Chapter 3 contains information on the machinability of titanium and its alloys. Chapter 4 is dedicated to the effects of alloying elements on the machinability of near-eutectic Al-Si casting alloys. Chapter 5 covers the machinability of hard materials. Finally, in Chapter 6, an investigation on ductile regime machining of silicon nitride ceramics is presented.
This book is a useful resource for students, academics, manufacturing researchers, mechanical, industrial and materials engineers, and professionals in fields related to machining and machinability of advanced materials.
