Effect of cutting speed on surface roughness and machined surface temperature (f = 0.13 mm/rev, d = 0.4 mm). Figure 3 shows the variations of the surface roughness (Ra) and machined workpiece surface temperature (T) with cutting speed. This enhances the thermal softening of machined workpiece surface due to rise of temperature with speed and resulted in improved surface finish
