“…The formation of serrated chips and shear bands was observed during the machining of titanium alloy, which complies with the finding of other studies [25,26]. The reason for the formation of serrated chips and shear bands in the machining of titanium alloy is that the thermal softening effect of titanium alloy is greater than that of the strain hardening effect and strain rate strengthening effect [9].…”

This paper first develops a cryogenic cutting system with adjustable jet temperature (− 196~20°C), and then carries out a series of dry cutting and cryogenic turning experiments for titanium alloy. Metallographic microscope is used to observe the chip morphology of titanium alloy and the geometric characteristic parameters of the chip are measured using a Digimizer image measurement software. The influence of cutting speed and cooling conditions on the chip morphology, chip height ratio, and serrated pitch has been analyzed. The experimental results reveal that the cutting speed and cooling conditions play significant roles on the chip morphology and serrated characteristics of titanium alloy. During the cryogenic cutting process, with the increase of cutting speed, the chip height ratio and serrated pitch of titanium alloy chip increase. It has been found that under the condition of cryogenic cutting, the lower jet temperature, the more obvious serrated characteristic of titanium alloy chip. It is also found that the fibrous adiabatic shear band exists in the shear zone; the chip height ratio and serrated pitch remarkably increase.

“…Minimum quantity lubrication is applied in machining of Ti-6al-4v to study its effectiveness [6][7][8][9]. Feasible conditions for MQL application in milling of Ti-6al-4V using cemented carbide tool were studied and found significant increase in tool life and reduction in average roughness value as per results of SEM/EDS analysis by [6].The oil supply rate in MQL plays an important role. Increasing the oil flow rate from 2ml/hr to 14ml/hr reduces cutting force and surface roughness [7].…”

Suddenly increased demand of titanium in Aerospace and medical industry is attracting the focus towards titanium machining now a days. Titanium in spite of several good properties like high strength to weight ratio and excellent corrosion resistance, it is one of the difficult to cut material because of its low thermal conductivity and high reactiveness at elevated temperature. Ninety percent of the aerospace parts require milling operation hence this paper focuses on milling operation. Titanium milling is constrained by low speed, feed and depth of cut during machining, low MRR, high temperature, costly tooling, and shorter tool life and requires high pressure coolant to be sprayed to cutting zone. All above constraints makes titanium difficult to cut and contribute towards increased environmental burden. Therefore it is necessary to find sustainable machining methods for titanium which will reduce coolant consumption and increase tool life without sacrificing the surface quality. This paper therefore focuses on experimental analysis using Taguchi based GRA to find influence of various factors on tool wear and surface roughness. Method of grey relational analysis is used for multi objective optimization. Taguchi L16 orthogonal array is used and flood cooling and MQL strategy is compared. The optimum combination consists of MQL at 200ml/hr flow rate, Speed 1000 rpm, Feed 0.06 mm/tooth and depth of cut of 0.6mm. At this combination the values of tool wear and surface roughness are 0.068mm and 0.271 micro meter respectively. The TiALN coated carbide milling inserts used for experimentation Cooling strategy is also taken as one of the factors for Study.
