Characteristics of the surface of a titanium alloy following milling with abrasive waterjets

Due to the differences in flow patterns, the erosion conditions are very different to those occurring in conventional cutting. This work examines the abrasive waterjet milling behaviour of Ti6Al4V in terms of the surface properties of the milled component, such as roughness, waviness and level of grit embedment. The properties of the surface following milling depend strongly on the milling parameters, such as jet-workpiece traverse speed, impingement angle, waterjet pressure and abrasive size.
