Abstract

This paper presents an approach to establish model and the efforts in optimization of tool life and surface roughness in end milling of titanium alloy Ti–6Al– 4V using uncoated WCCo inserts under dry conditions. Response surface methodology coupled with small central composite design (CCD) was employed in developing the tool life and surface roughness models in relation to primary cutting parameters such as cutting speed, axial depth of cut and feed. Flank wear has been considered as the criteria for tool failure and the wear was measured under a Hisomet II Toolmaker’s microscope. Mitutoyo surftest was utilized for surface roughness measurements. Design-expert version 6.0.8 software was applied to establish the first-order and the second-order models and develop the contours. The adequacy of the predictive model was verified using analysis of variance (ANOVA) at 95% confidence level.
