Abstract: In this study, the calculation method of the distribution of flank wear width over an entire cutting edge was proposed. The profile of nose part was traced on the image of an insert taken at the cutting position of orthogonal rake angle αs and parallel rake angle αb from vertically above using an image processing software. The traced lines were converted to the CSV files by a graph trace software. Comparing the profile of a worn insert to unused one, the recession of nose profile could be obtained. The distribution of flank wear width could be geometrically calculated from the recession of nose profile taking rake angle αs and αb into consideration. The accuracy of calculation was verified by comparing calculated wear width to directly measured one. As an example, the transitions of nose profile and distribution of flank wear width in turning of JIS SCM435 at different lubrication conditions were shown.
