WEDM of Aerospace Alloys Using Clean Cut Generator Technology

摘要：

The paper outlines recent development in EDM generator technology and presents experimental data for workpiece integrity relating to the WEDM of Udimet 720 and Ti-6Al-2Sn-4Zr-6Mo advanced aeroengine alloys using Clean Cut pulse technology. Typically, rough cutting (～100 mm2/min) produced a recast of<10 μm thick in both alloys, however following TriM 3/4 passes, this reduced to<3 μm with workpiece surface roughness～0.4 μm Ra and significantly reduced tensile residual stresses measured at the workpiece surface (by～600 MPa for Udimet 720 nickel based superalloy). Surface cracking, when evident, was restricted to within the recast layer.
