Abstract
This current work presents the machinability assessment in the end-milling of Titanium Alloy Ti-6Al-4V through workpiece preheating. End-milling tests were conducted using a Vertical Machining Centre machine with full immersion cutting. A 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 insert. Uncoated WC-Co carbide inserts were used in the experiments. All of the experiments were run at room temperature with preheating at 315, 450, and 650oC, and each test was started with a new cutting edge. High frequency induction heating was utilized during end-milling with preheating. Flank wear has been considered as the criteria for tool failure and the wear was measured under a Hisomet II Toolmaker's microscope. Further testing was stopped and an insert 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. Any vibration during cutting was captured using a vibration analyser. A Scanning Electron Microscope (SEM) was also used to investigate the wear morphology, wear mechanism and surface integrity of machined surface. The results conclude that workpiece preheating will significantly increase the tool life of uncoated WC-Co carbide inserts in end-milling of Titanium Alloy Ti-6Al-4V.
