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. © 2010 Springer-Verlag London.
