Abstract:

One of the most important issues to be addressed in hard cutting pertains to the evaluation of tool life as it is closely connected to machining quality and overall process cost. The attributes of tool life can be mathematically calculated based on machining conditions and other characteristics of the cutting process. In this paper the formulation developed for CBN tools, applied for the machining of 100Cr6 bearing steel is presented. Experiments were carried out for the validation of the theoretical approach. Additionally, a novel indicator, namely wear intensity, is analyzed and discussed, based on experimental results. Wear intensity is calculated as the ratio of flank wear to cutting length. From the analysis it can be concluded that the prognosis of tool life can be accurate with the proposed method. Furthermore, interesting and useful results are reported in connection to wear intensity and cutting speed in hard cutting.
