Magnetic Abrasive Finishing is a significant process for finishing up to the micro-level. However, with the advancement of technology and hybrids like Viscoelastic magnetic abrasive Finishing and Magnetic abrasive Flow machining, it has become a nano finishing process. To improve the finishing process, the researchers have made a Model and tested the feasibility of the wind turbine magnet in Finishing. The Maxwell simulations were done for the cylindrical Specimen of Brass, Steel Aluminum. The simulations results were in accordance with the fact that the proposed wind turbine magnet may be used for the simulations.
Thermal additive centrifugal abrasive flow machining (TACAFM) is a recent hybrid of abrasive flow machining to cater for its limitation of low material removal (MR) through spark formation and centrifugal action of centrifugal force generating (CFG) electrode. The geometry of the CFG electrode is a crucial parameter in determining the centrifugal action on media and spark formation. The present investigation proposed a novel triangular-shaped electrode for improving the efficiency of the TACAFM process. The validation of spark and flow parameters with the proposed electrode was analysed using ANSYS FLUENT@. The simulation results were further validated by experimentation and artificial neural network modelling. The effect of supply current, rotational speed of CFG electrode and number of cycles were analysed for MR and on percentage improvement in the surface finish (%ΔRa) on the brass workpiece by the proposed electrode. The experimental results show the average cumulative percentage absolute error obtained for MR is 0.33% and that for %ΔRa is 0.96%. The scanning electron microscopy images justify the machining performance through spark generation. The experimental results are in good confirmation of simulation results and highlight the suitability of the proposed electrode for the TACAFM process.
