TESTS with a Walter Prototyp carbide milling cutter have shown Airbus that it can transform its titanium machining capabilities, doubling cutting volumes during roughing operations on one workpiece. Applied to the Ti6AI4V alloy, a 25mm diameter Prototyp Ti40 solid carbide end mill removed 160-200cnf/min of material at feed rates of 50-60m/min. This compares with 80cm3/min at 25m/min using a 32mm HSS tool - cutting data that has characterised the Airbus workpiece since the mid-1990s.
