Tool Wear and Surface Integrity in End Milling of Ti6Al4V with Polycrystalline Diamond Tools

Article Preview

Abstract:

Titanium is a difficult-to-machine material due to its low heat conductivity and high chemical reactivity. It creates high tool wear and causes low machining efficiency. The strong relationship cutting forces between and tool wear and surface integrity of work piece makes it necessary to study the effect of dynamic cutting force on cutting tools to analyse the wear propagation and tool life. This paper investigates the tool wear on Polycrystalline Diamond (PCD) cutters in milling Ti-6Al-4V and analyses workpiece surface quality. Based on the experimental results of slot milling, cutting parameters that yields best surface finish were found.
