Abstract
This paper presents the results of an investigation of machinability improvement in end-milling of Titanium Alloy Ti-6Al-4V through workpiece preheating. End milling tests were conducted on the Vertical Machining Centre with full immersion cutting. Titanium alloy Ti-6Al-4V bar was used as the workpiece. Machining was performed with a 20 mm diameter end-mill tool holder fitted with one uncoated WC-Co carbide insers. Induction coil heating was utilized during end milling under preheated conditions. Flank wear has been considered as the criterion for tool failure and the wear was measured using a Hisomet II Toolmaker's microscope. Tests were conducted until an insert was rejected when an average flank wear greater than 0.30 mm was recorded. Cutting force and torque measurements were conducted using the Kistler Rotating Cutting Force Dynamometer. Vibration during cutting was captured using an online vibration monitoring system. The results lead to the conclusion that workpiece preheating significantly increases the tool life of uncoated WC-Co carbide inserts in end-milling of Titanium Alloy Ti-6Al-4V.
