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

摘要

Modern industrial materials have excellent properties. However, generally these materials are difficult-to-cut materials. In this Study, investigates characteristics effect of 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 (Ti-6Al-4V) under high-speed milling conditions. 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 and 0.15 mm/tooth, cutting speed 100-400 m/min and investigate 50, 100, 200 and 300 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 Ti-6Al-4V were at cutting speed 200 m/min, feed rate 0.1 mm/tooth. And in tool wear, Titanium wear is minimized at 200 m/min of cutting speed, feed rate 0.15 mm/tooth and Ti-6Al-4V is 100 m/min, feed rate 0.15 mm/tooth.
