The main disadvantage in non-conventional machining process is that the metal removal rate is much slower than conventional machining process.

Surface finish is poor too.

Smooth for soft material. But for hard the surface finish is poor.

Application:

This machining is used to machine hard and brittle material like carbide, ceramic, glass etc.

This is used in machining of die and tool of drill, wire drawing machine etc.

Used in fabrication of silicon nitrite turbine blade.

It is used to cut diamond in desire shape.

It is used machining of machining non-conductive hard material which cannot be machined by ECM or EDM due to poor conductivity.

Answer C is right.

MRR= ECM>EDM>USM>EBM>LSM.
