Turning performance analysis using coefficient of tool life in relation to the volume of removed material

Abstract:

The austenitic stainless steels are difficult material to machine due to their high strength, high ductility and low thermal conductivity. The aim of this paper is to propose a new criterion for assessing the performance of high speed turning by relating the flank wear with the volume of material removed. The influence of cutting parameters on the coefficient of life in relation to the volume of material removed was analyzed using analysis of variance and multiple regression. The investigation showed a better performance with the GC 2015 insert in both cutting speed. The analysis of factorial variance showed a significant effect of the machinization time in the coefficient of life in relation to the volume of material removed.
