Über dieses Buch

"Surface Integrity in Machining" describes the fundamentals and recent advances in the study of surface integrity in machining processes.

"Surface Integrity in Machining" gathers together research from international experts in the field. Topics covered include: the definition of surface integrity and its importance in functional performance; surface topography characterization and evaluation; microstructure modification and the mechanical properties of subsurface layers; residual stresses; surface integrity characterization methods; and surface integrity aspects in machining processes.

A useful reference for researchers in tribology and materials, mechanical and materials engineers, and machining professionals, "Surface Integrity in Machining" can be also used as a textbook by advanced undergraduate and postgraduate students.

1. Surface Integrity – Definition and Importance in Functional Performance
Abstract
This chapter presents an overview of the nature of the surface that results from manufacturing processes, as this nature has long been recognized as having a significant impact on the product performance, longevity and reliability. Surface alterations may include mechanical, metallurgical, chemical and other changes. These changes, although confined to a small surface layer, may limit the component quality or may, in some cases, render the surface unacceptable. A basic understanding of the changes in the condition of the surface is very much required if improvement in product quality is to be attained. Surface integrity (SI) reveals the influence of surface properties and condition upon which materials are likely to perform. It has long been known that the method of surface finishing and the complex combination of surface roughness, residual stress, cold work, and even phase transformations strongly influence the service behavior of manufactured parts as fatigue and stress corrosion.

2. Surface Texture Characterization and Evaluation Related to Machining
Abstract
Τhis chapter is aimed at providing current knowledge on the association of surface texture with machining, along with recent advances in surface characterization and evaluation. Various texture parameters, adopted by ISO standards or not, are described and their distinctive power is considered. Arithmetic parameters, statistical and random process functions serve as measures for rendering in-height and inlength surface characteristics and allow multiparameter analysis of the surface, something quite necessary under current high requirements for precision and operation. Theoretical models for roughness parameters and experimental trends with regard to machining conditions are discussed. Isotropy of machined surfaces is also considered and methods for surface typology are finally discussed.

3. Residual Stresses and Microstructural Modifications
Abstract
This chapter presents an “overview” of residual stresses and microstructural modifications in surface layers. Surface alterations may include mechanical, metallurgical, chemical and other changes in workpieces by machining. The applications of some of these concepts in turning, milling and grinding are discussed in this chapter.

4. Characterization Methods for Surface Integrity
Abstract
Since machined surface quality is a very important feature for numerous machine elements, many techniques have been developed to characterize and evaluate the surface integrity. This chapter reports a few general technologies used to characterize different aspects of the surface. In Section 4.1, some surface roughness measurement techniques will be introduced; in Section 4.2, X-ray diffraction and electron diffraction will be presented for crystalline structure; in Section 4.3, an X-ray energy-dispersive analyzer, Auger electron spectroscopy, and X-ray fluorescence are included for elemental analysis; Section 4.4 presents X-ray photoelectron spectroscopy and secondary ion mass spectrometry for chemical composition analysis; Section 4.5 reports the microcrystalline structure and dislocation density technology: transmission electron microscopy.

5. Surface Integrity of Machined Surfaces
Abstract
This chapter presents the basic knowledge on surface integrity produced in traditional and non-traditional machining processes. An extended overview of fundamental characteristics of surface finishes and surface integrity including surface roughness/surface topography, specific metallurgical and microstructure alterations and process-induced residual stresses is carried out. Surface roughness was determined by many important 3D roughness parameters and representative scanned surface topographies were included. They allow recognizing the structural features, i.e., determined and random components of the machined surfaces. Moreover, some practical formulae for prediction of the theoretical surface roughness in typical cutting operations (turning and milling) and grinding operations are provided. On the other hand, possible surface alterations resulting from abusive machining operations are demonstrated. Finally, the state-of-the-art of machining technology is addressed to many finishing cutting, abrasive and non-traditional (EDM, ECM, LAM, USM, etc.) operations to show how the manufacturing processes can be effectively utilized and optimized in practice.

6. Surface Integrity of Micro- and Nanomachined Surfaces
Abstract
Micro- and nanomachining processes are being developed that minimize the damage created due to the removal of materials at low and high material removal rates. In order to characterize the level of damage induced, the integrity of the workpiece surface requires to be measured. This chapter provides a state-of-the-art review of micro- and nanomachining and the measurement of surface integrity of micro- and nanomachined surfaces.
