Analysis of some aspects of surface integrity after grinding and hard turning

This paper deals with the application of Barkhausen noise for investigation of residual stresses after turning and grinding. Results illustrate the differences in stress distribution after turning and grinding. The analysis of stress state shows that Barkhausen noise can be easily applied to the identification of thermal load and therefore for monitoring of a grinding process. On the other hand, the conventional evaluation of Barkhausen noise fail and monitoring of surface integrity will require a subsequent modified approach. The main reason for it is a more complicated relationship between stresses, surface hardness and structure
