Abstract Achieving the reasonable tool life, surface quality, and residual stresses in the micromachining of difficult-to-cut materials is still a challenge. Titanium alloys are notorious among hard materials for poor thermal conductivity and hardness at elevated temperature leading to premature tool failure. The additive manufactured titanium is one-step beyond in hardness and put forward a real challenge, especially in the micro-milling. In these conditions, a minuscule cooling/lubrication is imperative to apply to reduce the accelerated tool wear and surface burning effects due to heat generation. This comparative study aims to analyze the lubri-cooling effects of minimum quantity lubrication (MQL) in the micro-milling of additively manufactured Ti–6Al–4V using coated tungsten carbide micro endmills under varying cutting speeds and feed rates.
