Surface Roughness Investigation of the Cutting Edge of the High Precision Cutting Tools Enabled by Micro and Nanometrological Measurements

The manufacturing technology of milling, drilling and turning tools have demands of new developing markets as well as quality and lifetime aspects of the machining. In order to achieve the high precision required by machining, the structure and form of the cutting edge of the tools must be investigated to provide the most influential properties. Correlation between the tool wear on the cutting edge regions and surface roughness variation is an important feature to evaluate the state of the tool edge in developing machining process that is possible through nanometrology. In this study, the high precision measurements compliant with the international standards are carried out to examine the cutting edge of the machining toll samples in both 2D and 3D metrological investigations. The micro and nano scale measurements have been stored in order to creative both qualitative and quantitavie data on edge cross-sections that is known to be the most fluential region for quality and life-time of the machining tools. The results have been discussed and a comprehensive analysis of the cutting edge investigation has been summarized.
