Description
Summary:It is likely for the interaction between the cubic boron nitride grains on the working surface of grinding wheels and maraging C250 steel workpiece to cause phase transformation, thus reducing the material removal rates and affecting the quality of the workpiece surface generated during grinding. Up to now, there remain few studies focusing on the relationship between grinding wheel topography and phase transformation. In this study, an analysis was conducted of the effects that the topography of cubic boron nitride grinding wheel has on the distribution of phase transformation and the surface quality of maraging steel during grinding. The phase transformation diffraction curve was plotted based on the results of X-ray diffraction (XRD) analysis, and then, it was compared with the known data under different grinding wheel conditions. The topography of the cubic boron nitride grinding wheel was characterized using 3D digital microscope analysis, and the dynamic abrasive grit density coefficient λ d for micro-grinding was proposed to clarify the effect of relevant parameters on phase transformation. The surface quality of grinding wheel and workpiece after grinding was analyzed, while the combination of different grinding wheel topography parameters and the process optimization scheme were proposed to achieve the optimal effect of grinding.
