Effect of the grinding parameters on surface topography considering vibration characteristics

There are many studies about the effects of grinding process parameters on the surface topography, but the influence of the vibration is rarely considered. In this paper, the grinding experiments are performed in the fine grinding stage of the slider raceway and the vibrations of the feed platform and the grinding wheel shaft are acquired simultaneously. The parameters such as the autocorrelation function, probability density function, the skewness and kurtosis and the distribution of the microstructure pits are used to characterize the surface topography. It reveals the influences of the process parameters on the surface topography by analyzing the influences on the maximum undeformed cutting thickness (MUCT) considering vibrations. The results show that the surface roughness increases with the feed speed within 25m/min while it decreases beyond this range since the MUCT will be reduced due to the effect of the vibration on the interference of the abrasive particles with the workpiece. The surface grinding quality becomes worse when the linear speed is in 30m/s~33m/s as the MUCT becomes larger because of the increase of the vibration of the grinding wheel shaft. Meanwhile, the SEM of the abrasive grain distribution shows that there is a phenomenon of scattering with the increase of the linear speed when it is close to the limit of 35 m/s.
