HERNANDEZ GONZALEZ, Luis W. et al. Effect of the removed metal volume and cutting speed in the cutting tool wear during high speed turning of AISI 1045. Ing. Desarro. [online]. 2011, vol.29, n.1, pp.62-83. ISSN 0122-3461.

This work deals with the experimental study of the effect of the removed metal volume and cutting speed on flank wear of two coating carbide and a cermet inserts during the dry finishing turning of AISI 1045 steel at moderate, medium and high cutting speeds. The results were compared using the volumetric dimension of the cutting tool life, the variance analysis and lineal regression analysis in order to describe the relationship between the flank wear and removed volume, obtaining the adjusted model equations. The investigation showed a significant effect of cutting speed and machined metal volume on the flank wear, achieving that the three coating layers insert demonstrated the best performance while the two layers insert had the worst behaviour of the cutting tool wear at high cutting speed.
