An experimental study was undertaken to investigate the role of process parameters on the grindability of medium carbon steel in a high-speed grinding domain with particular emphasis on surface integrity. Surface residual stress on the ground specimens has been assessed using X-ray diffraction technique and Barkhausen noise analysis. High-speed grinding with cubic boron nitride (cBN) wheels, unlike conventional grinding, provided compressive residual stress throughout the experimental domain. This can be attributed to a desirable temperature control as the single layer cBN wheel with higher thermal conductivity than conventional wheels and grinding fluid took away a substantial part of the grinding heat flux. Micromagnetic or Barkhausen noise parameters correlated linearly with the residual stress, indicating its applicability in assessing the surface integrity of high-speed ground steel.
