Data from: Optimization of parameters in cylindrical and surface grinding for improved surface finish

Surface integrity has attracted attention of the researchers for improving
the functional performance of the engineering products. Improvement in
surface finish, one of the important parameters in surface integrity, has
been attempted by researchers through different processes. Grinding has
been widely used for final machining of components requiring smooth
surfaces coupled with precise tolerances. Proper selection of grinding
wheel material and grade with grinding parameters can result in improved
surface finish improved surface characteristics. Present work reports the
study of the effect of grinding parameters on surface finish of EN8 steel.
Experiments were performed on surface grinding and cylindrical attachment
for optimization of grinding process parameters for improved surface
finish. Grinding wheel speed, depth of cut, table feed, grinding wheel
material and table travel speed for surface grinding operation and work
speed for cylindrical grinding operation were taken as the input
parameters with four types of grinding wheels (Al2O3 of grade K and L, and
white alumina of grade J and K). The surface roughness was taken as output
parameter for experimentation. The grinding wheel material and grade have
been observed as the most significant variables for both the cylindrical
grinding and surface of grinding. Surface roughness in case of surface
grinding is better compared to cylindrical grinding which can be
attributed to vibrations produced in the cylindrical grinding attachment.
Surface roughness (Ra) value of 0.757 µm in cylindrical grinding and 0.66
µm in surface grinding has been achieved.
