Abstract

A method and associated apparatus are described for assessing a rotatable cutting tool (50) having a plurality of cutting edges (58) that extend along its length (L) that is carried by a machine tool (4). The machine tool comprises a tool measurement device (2), such as a non-contact tool setting apparatus, for measuring the cutting tool (50). The method comprises using the tool measurement device (2) to measure a cutting edge profile (100,102; 120, 122; 300, 302) of each of the plurality of cutting edges (58). These cutting edge profiles (100,102; 120, 122; 300, 302) are together used to assess if any workpiece defects would be generated when machining a workpiece using the cutting tool (50). In particular, the method assesses if any cutting edge defects are present on more than one of the plurality of cutting edges (58) at a plurality of axial locations along the length of the cutting tool (50). In one embodiment, a composite tool profile (304) is used to assess if such defects are present. In this manner, it can be predicted if a cutting tool defect will result in a workpiece defect when that cutting tool is used.
