“…Many researchers studied the effect of machining conditions entailing direct influences such as process parameters and tool properties [6,11] and indirect conditions affected surface roughness during machining such as cutting force, generated temperature and tool wear by machining [12,13]. Nithyanandam et al [14], studied the effect of process parameters on generated surface roughness by turning tests of Ti6Al4V alloys.…”

Surface finish of machined parts is a significant quality mark for a range of applications such as aerospace, automotive, power transmission and generation. Therefore, optimization of surface roughness is the key factor for reliability in machining difficult-to-cut materials such as titanium-based alloys. In this study, an investigation into hard turning of Ti6Al4V alloys with varying process parameters and cutting tool materials was carried out. This study aims to compare the generated surface roughness when turning Ti6Al4V alloys using CBN and coated ceramic inserts, independently, under the same values of feed rate, cutting speed and depth of cut. The experiments were designed using Taguchi L9 and the exponential results were examined by the analysis of variance (ANOVA). The effect of process parameters and their interactions on generated surface roughness was evaluated for the two inserts. It was found improvement of surface roughness by 34% was achieved when using coated ceramic insert compared with the results obtained using CBN insert under the same range cutting conditions. CBN insert gave a better result at smallest depth of cut (0.15 mm), low feed rate (0.1 mm/rev) and high cutting speed (100 m/min) while coated ceramic tool gave a minimum surface roughness at depth of cut (0.2 mm), feed rate (0.1 mm/rev) and high cutting speed (100 m/min).

“…The results showed that positive rake angle gave a better result with high speed machining as it results in low cutting force and cutting temperature. Devin et al [14] stated that cutting temperature increased by increasing machining time. As the high temperature generated is the main problem during machining titaniumbased alloys, selection of appropriate cutting tool is important factor for high reliability levels [15].…”

Characteristics of cutting insert are key factors for the reliability of machining of difficult-to-cut materials such as Ti6Al4V alloy. Therefore, in this paper a comparison between the performance of two different materials, ceramic insert coated by (Al2O3+TiNC) and CBN, when turning Ti6Al4V alloy in dry environment. Effect of process parameters, feed rate, cutting speed and depth of cut, and their interactions on measured cutting temperature were examined for both inserts. Taguchi method was utilized to design of experiments (L9) and the results were analyzed by analysis of variance (ANOVA). From the results, CBN insert showed a good behavior for heat dissipation during machining compared with coated ceramic insert with a reduction in cutting temperature by 28%. Moreover, it was found that cutting temperature increased by increase in cutting speed and depth of cut and decrease in feed rate when using the two types of insert. In addition, it was observed that cutting temperature was affected by varying process parameters when machining by CBN insert more than the case of coated ceramic tool. The significant parameter affected cutting temperature in the case of CBN was feed rate followed by cutting speed. While at coated ceramic insert, the most significant parameters effect on cutting temperature was cutting speed.
