Studies have confirmed the presence of white layer in hard turning and grinding surfaces are. Although they are usually associated with surface residual tensile stress, but the white layer may also indicate the residual compressive stress. Anyway, causes whitening layer and they have not fully understood the workpiece.

Some studies suggest the use of cutting fluid helps to eliminate whitening layer, while others show no coolant effect. There is some evidence that the tool working conditions affect the formation of albino layer. Overall, the new tool tends to produce more non-destructive surface layer increases with increasing the whitening tool wear increases. This may increase the flank wear after heat produced by the friction generated between the tool and the workpiece causes caused, or by increased friction results in a higher plastic deformation.
