    Abstract

    Cutting performance of uncoated WC/Co and TiCN coated solid carbide tools when end milling titanium alloy, Ti-6Al-4V was carried out investigated. Tool wear, tool life and cutting forces were investigated during end milling at various cutting speeds. Results showed that uncoated endmill outperformed TiCN coated endmill with regards to tool life at cutting speeds 130 m/min and below. However TiCN coated tools was more superior when endmilling at higher cutting speed. Both tools suffered nonuniform flank wear and chipping at the main cutting edge at most cutting conditions. In general, cutting force was slightly higher when machining with TiCN tool as compared to the uncoated tool. Similar trend of decreasing cutting force with increasing cutting speed was observed on both tools. At higher cutting speed, the effect of TiCN coatings on the cutting force was not significant when the difference in cutting force was very marginal between both tools. Keywords—Cutting Force, End Milling, Tool Life, Titanium Alloy, Tool Wear.
