Cutting condition deterioration and tool wear influence the image of the machined surface. Change in image is distinctly noticeable from the energetic point of view. Singular value decomposition (SVD) method is a factorisation technique which effectively reduces machined surface image into a smaller portion of data. Analysis of the eigenvalues of a machined surface image makes possible their application in the estimation of tool wear ER -
