Ti6Al4V Malzemesinin Mikro Frezeleme İşleminde Sonlu Elemanlar Yöntemi İle Kriyojenik Soğutmanın Etkisinin İncelenmesi

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