Traceable measurements of rounded cutting tool edges

Anaïs Nicolet & Felix Meli
The edge geometry of a cutting tool is of extreme importance for its performance and thus of great interest to the machine tool industry. The sharp cutting edges are processed to obtain specific edge roundings. Commercially available optical edge shape measuring instruments require suitable calibrated edge artefacts in order to achieve traceability. This study uses a specially adapted tactile profiler measurement method and a tailored evaluation program for the calibration of various cutting tool edge...
