High Performance Milling of Titanium Alloys

 


Milling of titanium alloys is known as a difficult process due to a high thermal tool load and a low modulus of elasticity. The high thermal tool load only allows low cutting speeds. Nevertheless, premature tool wear and failure occurs due to thermal wear mechanisms during the process.
The low modulus of elasticity of titanium alloys leads to an elastic push back of the workpiece material. Behind the cutting edge the workpiece material springs back and grinds at the flank face of the tool. Additionally, the low modulus of elasticity results in process vibrations which lead to poor surface quality and high dynamic tool and machine tool load. The described characteristics of titanium alloys require the use of adapted lubricoolant and cutting strategies.
