High-speed milling characteristic of the Ti and Ti-6Al-4V using TiAlN coated carbide radius end mill

Abstract

Modern industrial materials have excellent properties. However, generally these materials are difficult-to-cut materials. In this Study, investigates the effect of the characteristics cutting conditions of various materials using TiAlN coated carbide radius end mill to tool wear and surface roughness. That is Titanium(Ti) and Titanium Alloy(Ti6Al4V) under high-speed milling condition. The cutting conditions are as follows, end mill diameter: 6 mm, corner radius: 0.5 mm, 4 blades, and depth of cut: 0.2 mm, pick feed: 0.1 mm, feed rate: 0.1, 0.15 mm/tooth, cutting speed 100-400 m/min and investigate 50-500 m of cutting length. The experimental tests were carried out in the dry cutting condition. In surface roughness, optimized cutting condition of titanium were at cutting speed 200 m/min, feed rate 0.15 mm/tooth and Ti6Al4V were at cutting speed 400 m/min, feed rate 0.1 mm/tooth. And in tool wear. Titanium wear is minimized at a 200 m/min cutting speed, feed rate 0.15 mm/tooth and Ti6Al4V is 100 m/min, feed rate 0.15 mm/tooth.
