Preface
A surface can be defined as a border between a machined workpiece and its environment. The term surface integrity describes the state and attributes of a machined surface and its relationship to functional performance. In general, surface integrity can be divided into two aspects: first the external topography of surfaces (surface finish) and second, the microstructure, mechanical properties and residual stresses of the internal subsurface layer. For example, surface integrity is commonly defined as “the topographical, mechanical, chemical and metallurgical state of a machined surface and its relationship to functional performance”. Performance characteristics that are usually sensitive to surface integrity include, for example, fatigue strength, fracture strength, corrosion rate, tribological behavior (friction, wear and lubrication, dimensional accuracy, etc. This book aims to provide the fundamentals and the recent advances in the study of integrity surface in machining processes. Chapter 1 of the book provides the definition of surface integrity and its importance in functional performance. Chapter 2 is dedicated to surface texture characterization and evaluation. Chapter 3 describes residual stresses and microstructure modification, as w
