Abstract


The titanium alloy Ti-6Al-4V is a popular choice in the aerospace and medical sectors due to its exceptional mechanical properties, corrosion resistance, and biocompatibility. However, machining this alloy can be challenging due to its high strength and low thermal conductivity, which can result in accelerated tool wear and suboptimal surface quality. This experimental investigation examines the relationship between cutting speed, surface roughness, and tool wear during the milling of Ti-6Al-4V alloy. The selection of an appropriate cutting speed is crucial for enhancing surface finish and prolonging tool life. Experimental findings confirmed that cutting speed significantly influences both surface roughness and tool wear. Higher cutting speeds were associated with increased roughness and accelerated tool wear rates. The study successfully identified an optimal cutting speed that minimizes surface roughness while effectively managing tool wear, contributing to improvements in the overall efficiency of the Ti-6Al-4V alloy milling process.
