Synopsis

Grinding is characterised by high specific energy and high grinding temperature that often leads to thermal damages and poor surface integrity, particularly induction of tensile residual stress. Residual stress on ground component can be reliably assessed by x-ray diffraction (XRD) technique, but the same is basically a laboratory based procedure and time consuming. Micro-magnetic technique like Barkhausen Noise (BN) provides much faster in-situ measurement of residual stress but is restricted to ferromagnetic work material and it needs calibration. The main aim of the current work is to evaluate applicability of BN technique to assess surface integrity aspects, with emphasis on residual stress, in grinding. The study encompasses two work materials ground using three grinding techniques to cover a wide experimental domain. The experimental results indicate successful application of BN technique in assessing surface integrity of ground components despite simultaneous change in state of stress, hardness and grain size of the work material. The present work introduced the novel signal processing technique for work materials exhibiting poor BN response.
