- Wire EDM Surface Finish – Electrical discharge machining Roughness . . .
The surface finish achieved through electrical discharge machining (EDM) varies: oil cutting can achieve Ra 0 2μm, water cutting Ra 0 4μm, and EDM surface finish usually ranges between Ra 0 2-0 3μm, typically around Ra 0 6-0 8μm

The Waviness is the measure of surface irregularities with a spacing greater than that of surface roughness These usually occur due to warping , vibrations , or deflection during machining
