Surface Integrity in Grinding Medium Carbon Steel with Miniature Electroplated Monolayer cBN Wheel

Surface Integrity in Grinding Medium Carbon Steel with Miniature Electroplated Monolayer cBN Wheel An experimental study was undertaken to investigate the role of process parameters on grindability of medium carbon steel with particular emphasis on surface integrity. Grinding with miniature monolayer electroplated cBN wheels provided compressive residual stress throughout the experimental domain unlike conventional grinding. This can be attributed to desirable temperature control as the wheel takes away substantial part of grinding heat flux owing to its better thermal conductivity. Micromagnetic or Barkhausen Noise (BN) parameters correlated linearly with the residual stress indicating its applicability in assessing surface integrity of cBN ground products. Increase in maximum grit depth of cut (h m) provided more grain elongation and surface hardness due to more chip load during chip formation. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Materials Engineering and Performance Springer Journals

Abstract

An experimental study was undertaken to investigate the role of process parameters on grindability of medium carbon steel with particular emphasis on surface integrity. Grinding with miniature monolayer electroplated cBN wheels provided compressive residual stress throughout the experimental domain unlike conventional grinding. This can be attributed to desirable temperature control as the wheel takes away substantial part of grinding heat flux owing to its better thermal conductivity. Micromagnetic or Barkhausen Noise (BN) parameters correlated linearly with the residual stress indicating its applicability in assessing surface integrity of cBN ground products. Increase in maximum grit depth of cut (h m) provided more grain elongation and surface hardness due to more chip load during chip formation.
