“…Table 1 shows the physical characteristics of heat treatment Ti6Al4V. According to the literature, TiAlN coated WC (tungsten carbide) material tools recommended for the machining of hard materials were selected [20][21][22][23][24]. The geometric features of the 4-flute end mill tool are given in Table 2.…”

“…Since cryogenic cooling causes hardening in the material, it increases the cutting forces Shokrani et al [47] There is uncertainty in the literature regarding the effect of cryogenic cooling on measured shear forces. Some empirical-based studies have concluded that cryogenic application in Ti6Al4V processing leads to an increase in shear force [20][21][22][23][24] due to an increase in hardness and strength in the workpiece.…”

“…Imbrogno et al (2017) applied 3D FEM to observe cutting forces, temperature, and microstructure during Ti6Al4V turning in a dry and cryogenic. They observed that cryogenic cooling is increased the shear forces and contributed to the improvement in surface roughness [23]. Pashaki and Pouya (2017) studied the temperature changes in dry and cryogenic processing of aluminum alloy with FEM.…”

Original scientific paperThe objective of this study is to see for micro-milling of Ti6Al4V in the different parameters, how wear occurs on the face of the tool and how to evolve cutting temperature, forces, and chip formations with FEM. The effects of dry, liquid coolant and LN2-based cryogenic cooling applications at 50,100,150 m/s cutting speeds and 1,2,3 μm/dev feed rate were compared in micro-milling of Ti6Al4V alloy. At different parameters, internal and workpiece-cutting edges cryogenic (wacec) are simulated temperatures were observed. Cryogenic cooling, dry and liquid coolant applications perceived that tool wear, chip formation, strain, stresses, and shear forces interpreted with the FEM. Also, a mesh model based on Arbitrary Lagrangian-Eulerian (ALE) simulations and the Johnson-Cook Plasticity model for material plasticity failure criterion are used in this study. As a result, indicated that at the cutting velocity of 100 m/min, cryogenic cooling on the workpiece and cutting edges has caused into decreasing %57 of cutting temperature also by %54 lower tool wear was observed on the internal tool cryogenic, by %15 the shear stresses decreased on wacec in comparison to dry cutting.
