Abstract: This paper presents an approach to optimize the surface finish in end milling titanium-alloy of Ti-6Al-4V using uncoated WC-Co and PCD inserts under dry conditions. Response surface methodology is utilized to develop an efficient mathematical model for surface roughness in terms of cutting speed, feed and axial depth of cut. For this purpose, a number of machining experiments based on factorial design of experiments method are carried out in order to determine surface roughness values. The 3FI surface roughnes… Show more

“…The surface roughness (Sa) of the EBM parts after milling vary between 0.11 and 0.17 µm. Similar roughness values after milling of conventional Ti6Al4V were achieved by Ginta et al [35], Zhang and Li [36], and Al-Rubaie et al [37]. The average roughness of the surface (Sa) is much lower when the tool movement is perpendicular to layer planes (TLP) than that the other two orientations (TPLP, and TILP).…”

“…In addition, the microstructural features of EBM Ti6Al4V indicate lower machinability in comparison with conventional Ti6Al4V [32]. Ginta et al [35] predicted the minimum surface roughness (0.17 µm) produced in end milling of titanium alloy Ti6Al4V using uncoated inserts under dry conditions. They employed a central composite design of response surface methodology to create an efficient analytical model for surface roughness in terms of cutting parameters: cutting speed, axial depth of cut, and feed per tooth.…”

“…For the machining of nickel-based materials, hardening precipitation and diffusion affinity lead to premature wearing of cutters. The better the cutters are in heat resistance, the greater the n value is (Chen and Ho, 2019; Hadzley et al, 2015;Ginta et al, 2009;Muñoz-Sánchez et al, 2011). The tool wear is closely related to material removal rate which is proportional to feed rate, machining depth and width.…”
