Surface Integrity in Notches Machining

Abstract:

Precision machining of soft and hardened materials is a topic of high interest to substitute some traditional operations. This paper deals with some aspects of the precision machining of notches. All machining processes result in changes of surface layer properties. There are changes in residual stresses, in harness, changes in material structure etc. and also in surface accuracy and surface roughness. All these characteristics may affect fatigue cracks in machined parts.
