Abstract

In the present study, an attempt has been made to investigate the influence of cutting speed, depth of cut, width of cut and feed rate on tool wear during machining of STAVAX material. The experiments were conducted on a 5-axis CNC milling Machine using Carbide steel ∅6 ball nose end mill insert. The tool wear is found to be significantly affected by width of cut and affected by feed rate, spindle speed and depth of cut but not as significantly as obtained from the ANOVA analysis. The contributions in order are width of cut at 57.47%, feed rate with 30.69%, spindle speed with 9.27% and error accounting for 2.57%. The most optimal cutting parameters in the context of this study is found to be 0.08mm depth of cut, 0.07mm width of cut, 13000rpm spindle speed and 2500mm/min feedrate. This combination of cutting parameters gives the lowest amount of tool wear, VB, at 0.1678mm.
