Abstract: Alumina being a lowest-cost high-performance ceramic is considered when seeking an alternate material for increased wear resistance, improved chemical resistance, dimensional stability, decreased friction and higher temperature use. Ultrasonic machining is a valuable process for the precision machining of such materials. In the present work, the mechanism of material removal by Silicon Carbide abrasives in alumina based ceramics with no sub-surface defects using USD process has been simulated. The Finite element method (FEM) software, ANSYS 5.4 is used for stress analysis under assumptions. The boundary conditions are applied. The theory of Zhang et al. (1999) for the number of abrasives under the tool is assumed to fit in the present model. The stress analysis confirms that the mechanism involved in material removal of brittle materials is initiation and propagation of the median vent cracks and lateral cracks. Fracture at the exit of hole was observed during experimentation. The material removal rate initially increases and then decreases with the increase of power input. The variation of MRR with respect to feed rate is very high, when compared to the variation due to power rating and slurry concentration. It is concluded that the Finite element model developed for the interaction of the abrasive and work piece is predicting the stress pattern with reasonable accuracy. The results of FEM analysis are validated by conducting experiments as per Taguchi's L9 OA.
