You can increase tooling life by high pressure cooling aimed directly at the tool tip while cutting. Use 55m per minute cutting speed and keep the feed high (the higher the better above 80 microns) but below 120 microns where the cut metal will start to stick to the surface of the tool causing heat buildup. Use a round tip for cutting wherever possible to spread out the heat at the point of contact. The stiffness of the machine is very important as well, to reduce tool deflection. Since the elasticity of titanium is part of the problem, you don't want to add any deflection due to the machine setup. Most production machines are not stiff enough to machine titanium in their standard configuration.
Except for the Automag in front, its usually the man behind the equipment that counts.
