Abstract
In grinding, the surface roughness of a workpiece has a significant influence on quality of the part. Surface roughness is heavily dependent upon. This article presents empirical research for determining influence of lubrication parameters on surface roughnes. The experiment is carried out with 36A60LV grinding wheel, Tectyl cool 290MC and Emulsion lubricant. Minitab 16 software is used to analyze test results to gauge the influence of lubrication parameters on surface roughnes. The regression equation that presents the relationship function of surface roughness is solved to determine the optimal value of lubrication parameters for each type of lubricant, and the values of surface roughness in two lubricant types are compared. The influence of flow and concentration of lubricant on surface roughness is quite complicated. When the flow of the solution and the solution concentration is increased, the surface roughness tends to decrease. However, if the values of these two parameters further increase, the surface roughness tends to increase. When the lubricant Tectyl cool 290MC is used, the value of surface roughness is smaller than it is when Emulsion is used. In fine grinding conditions, with Tectyl cool 290MC lubricant, if the values of the flow and concentration of lubricant are 2.62 (L/min) and 4.2 (%) respectively the surface roughness will reach the smallest value at 0.41 (μm). For Emulsion lubricant, if the values of the flow and concentration of lubricant are 2.63 (L/min) and 4.32 (%) respectively, the surface roughness will reach the smallest value at 0.49 (μm).
