Laser pre-structure-assisted micro-milling of Ti6Al4V titanium alloy

Abstract High flexibility of the micro-milling process compared to nontraditional methods has led its growing application in manufacturing complex micro-parts with tight tolerances and high accuracies. However, difficulties such as tool deflection, size effect, wear limit micro-milling. In this regard, role laser-assisted machining (LAM) is highlighted prevent mentioned issues through reduction forces providing possibility for using higher feeds. Ti6Al4V a hard-to-machine material chosen workpiece material. Unlike traditional LAM, parts were structured picosecond laser before The influence structuring at different structure densities on was analyzed two feeds 10 50 µm/tooth constant cutting speed 35 m/min. A remarkable observed both Additionally, density force highlighted.
