“…In order to model the behavior of TWR for 4 TC and the second-order model was selected taking into account the P values obtained for the lack of fit tests (where the p value is less than 0.0001 respectively). According to this, the model of the TWR turned out to be significant.…”

“…In the same way as for the TWR and taking into consideration the P values of the lack of fit tests, the second model was selected to model WLT in the case of 4 TC (P value is less than 0.0001 which indicates that the model is significant). From the Table 8, the significant factors are discharge current, pulse on time and pulse off time that the P values of each other is less than 0.05.…”

“…According to the research of Ti-6Al-4V alloy machining by EDM about recast layer/white layer is less. Because of the Ti-6Al-4V alloy properties such as high strength-to-weight ratio, high temperature stability and good corrosion resistance are classified as difficult-to-cut materials [4]. However, the Ti-6Al-4V alloy is commonly used in the important industries such as aerospace; the recast layer/white layer machined by EDM will have a great effect on the finished workpiece.…”

Electrical discharge machining (EDM) is common used process in aviation industries for machining micro-hole on the blade in aeroenging.Ti-6Al-4V is widely applied in frontier for its excellent properties such as a high strength-weight ratio, great heat stability and exceptional corrosion resistance. The micro-hole plays an important role in the micro-parts. In the present study, the mathematics models have been developed for relating the responses as the tool wear ratio and white layer thickness to input parameters like pules-on time, pule-off time and discharge current in a die-sinking EDM process. The response surface methodology has been applied for developing the models using the technique of design of experiment (DOE). The experiment plan adopts the centered central composite design (CCD).The experimental and predicted values were in a good agreement.

“…However, titanium and its alloys are difficult to machine materials owing to several inherent properties of the material. Titanium is very chemically reactive with almost all cutting tool materials and its low thermal conductivity and low modules of elasticity also impairs machinability [3]. The traditional machining techniques are often unable to machine the alloy economically.…”

“…Increasing the productivity and the quality of the machined parts are the main challenges of industry; there has been increased curiosity in checking all aspects of the machining process. Haron et al (2005) explored that titanium alloys are generally used for a component, which requires the greatest reliability; therefore the surface integrity must be maintained. Straight grade cemented carbides are suitable for use in machining titanium alloy 64.…”

This paper investigates the effect of cutting parameters on the surface roughness and cutting force of titanium alloy Ti-6Al-4V ELI when turning using PVD TiAlN coated tool in dry environment. Taguchi L9 orthogonal array design of experiment was used for the turning experiment 2 factors and 3 levels. Turning parameters studied were cutting speed (50, 65, 80 m/min), feed rate (0.08, 0.15, 0.2 mm/rev) and depth of cut 0.5 mm constant. Linear and second order model of the surface roughness and cutting force has been developed in terms of cutting speed and feed. The results show that the feed rate was the most impact factor controlling the cutting force and surface roughness produced. MINITAB 17software was used to develop a linear and second order model of surface roughness and cutting force. Optimum condition was at 66.97 m/min of cutting speed, 0.08 mm/rev of feed rate. Surface roughness 0.57μm and cutting force 54.02 N were obtained at the optimum condition. A good agreement between the experimental and predicted surface roughness and cutting force were observed.
