In the present study experiments are conducted to find optimum value of input parameters for minimum surface roughness. The selected input parameters are grinding wheel speed, work-piece speed, abrasive grain size, depth of cut, concentration of cutting fluid, and number of passes while surface roughness and out-of-roundness are desired responses.
Jan 22, 2010· Since surface roughness of Rmax/Rz=1.6s can be achieved, hard turning is often considered a replacement for grinding operations or as a pre-grinding process. Hard turning is most often performed on post-heat treated parts with surface hardness ranging .

From observations of individual grinding scratches and an analysis of the experimental results, it is concluded that virtually all of the grinding energy is expended by viscous deformation. Material removal occurs by flow into chips with silicon carbide abrasive and by brittle fracture preceded by viscous deformation with diamond abrasive.
Instead of the work being supported between centers, as in the older cylindrical grinding, it is supported by means of contact with the grinding wheel, the regulating wheel, and the work blade. In this paper, the methods of analysis already developed and used to examine other machining processes [1, 2] are extended and applied to centerless grinding.
