Material removal in AJM takes place due to brittle fracture of the work material due to impact of high velocity abrasive particles.
Modeling has been done with the following assumptions:
(i) Abrasives are spherical in shape and rigid. The particles are characterized by the mean grit diameter
(ii) The kinetic energy of the abrasives are fully utilized in removing material
(iii) Brittle materials are considered to fail due to brittle fracture and the fracture volume is considered to be hemispherical with diameter equal to choral length of the indentation
(iv) For ductile material, removal volume is assumed to be equal to the indentation volume due to particulate impact
