Electrochemical Discharge Drilling of Inclined Micro Holes with Step Feeding Method

International Journal of Electrochemical Science, 2020
Film cooling holes are distributed mainly on the surface of turbine blades, with center lines at angles to the tangential direction. These “inclined micro holes” (IMHs) are difficult to machine because of their extremely small diameters, the challenge of

Modeling the nano indentation behavior of recast layer and heat affected zone on reverse micro EDMed hemispherical feature

, 2021
Electrical discharge machined surfaces inherently possess recast layer on the surface with heat affected zone (HAZ) beneath it and these have a detrimental effect on the mechanical properties viz., hardness, elastic modulus, etc.

Effect of no-load rate on recast layer cutting by ultra fine wire-EDM

Chinese Journal of Aeronautics, 2021
Abstract Via material erosion in wire electrical discharge machining (WEDM), recast layers form on the surfaces of workpiece. In addition, ultra fine Wire-EDM can be usually cut once. To reduce the thickness of the recast layer as much as possible, the wire electrical discharge-electrochemical machining (WEDCM) method was proposed, which is based on ...
