“…These result are comparable with the findings of research where similar analysis and experiments were performed on Ti-6Al-4V opting high speed machining (Bajpai et al, 2013;Jaffery et al, 2016;Kim et al, 2014;Thepsonthi and Özel, 2013). Increase in cutting speed is accompanied by decrease in cutting force (Jaffery and Mativenga, 2009;Pathak et al, 2013) and as cutting speed decreases contact time of tool with the chip is reduced.as a result less heat is transferred into the chip and more heat is transferred into the tool tip (Rosemar et al, 2013). Temperature in the shear zone is expected to rise at higher cutting speeds but the friction between the tool rake face and chip is reduced thereby reducing the welding phenomenon between chip and workpiece and heat generation at the tool chip interface (Prasad, 2009) as a result reduction in burr formation takes place.…”

Abstract. The use of titanium based alloys in aerospace and biomedical applications make them an attractive choice for research in micro-machining. In this research, low speed micro-milling is used to analyze machinability of Ti-6Al-4V alloy as low speed machining setup is not expensive and it can be carried out on conventional machine tools already available at most machining setups. Parameters like feed per tooth, cutting speed and depth of cut are selected as machining variables and their effect on burr formation is analyzed through statistical technique analysis of variance to determine key process variables. Results show that feed per tooth is the most dominant factor in burr formation (81 % contribution ratio). The effect of depth of cut was found to be negligible. It was also observed that micro-milling at optimum process parameters showed minimum burr formation. In terms of burr formation, as compared to high speed machining setup, better results were achieved at low speed machining setup by varying machining parameters.

“…Grain size reduction, hardening, and formation of strain-induced α' martensite are common features of abusively machined stainless steels. During milling, a fraction of the austenite phase transforms to α' martensite and  martensite, the remaining austenite deforms by slip or twinning [7]. The surface mechanical properties change greatly adjacent to the surface due to the combined effect of the fine grain size and the presence of a complex deformed layer.…”

“…Additionally, the heat generated during machining can contribute to increasing the overall tensile stress field [6]. Excessive plastic deformation in stainless steels is also known to promote the formation of strain-induced martensite, ultimately reducing the ductility of the finished surfaces and adding to the development of residual stresses due to the volume misfit between the transformed phase and austenite [7].…”

A Design of Experiments (DoE) approach was used to characterise the effects of dry machining at abusive conditions on the austenitic stainless steel AISI 316L. Surface roughness, hardness, martensite fraction, residual stresses and surface defects (welded chips, cracks) were evaluated against the cutting parameters (speed, depth-of-cut and feed) to build a model weighting their contribution. Results are presented in colour contour plots which allow for an in-depth understanding of the parameters' combined effects on the surface properties of the material upon dry milling. Using the statistical model it was possible to identify optimum combinations of cutting parameters on the grounds of minimising undesirable effects on the material. Eventually, a sample "risk of failure" map was derived by evaluating the impact of the process parameters' statistical variations.

“…Additionally, the variation of geometric features also causes the vibration of machine tool, which seriously affects the high-speed milling. As the cutting force is one of the most important process parameters [15,16], the optimization process of machining parameters for high-speed milling of titanium alloy curved surface should be conducted to guarantee the smooth change of cutting force.…”

The development of high-speed milling technology provides an effective processing method for titanium alloy curved surface with high quality, and the spindle speed is an important machining parameter for the high-speed milling of titanium alloy curved surface. The variation of the geometric features of the titanium alloy curved surface results in the sharp fluctuation of the cutting force as well as the vibration of machine tool, which not only makes a severe impact on the surface machining quality and the tool life but also greatly affects the efficiency of the high-speed milling. An experimental study is carried out to determine the spindle speed for high-speed milling of the titanium alloy curved surface based on the cutting force. The experimental results indicate that in high-speed milling process, the cutting force is associated with the geometric feature of the curved surface and the change of cutting force is relatively smooth when the spindle speed is in the range from 9000 to 13,000 rpm for the machining of titanium alloy curved surface.
