ABSTRACT

Abrasive Flow machining (AFM) also called Abrasive machining process which helps in achieving high level of surface finish and material removal rate from internal complex workpiece geometries after the machining operation. Concentration of abrasive, Abrasive size, extrusion pressure, media flow rate, number of strokes, media viscosity, strain rate and velocity are the factors which affect quality surface finish and MRR. Mathematical modelling, experimental results and computational simulation helps in improving the performance of Abrasive flow machining. This paper focuses mathematical model and computational simulation for the internal surface irregularities and effect of parameters with different media flow velocity. Computational Fluid dynamics (CFD) simulation was executed using commercial codes software available ANSYS FLUENT. CFD used numerical and algorithms methods (discrete counterparts of the governing equation) to analysis and get solution to the fluid flow problem. The fluid is assumed to be Newtonian fluid and type of flow should be steady, laminar and incompressible. Fluent Multiphase Mixture model for two phases was taken in account with secondary phase as continuous. The base media consist of Silly putty (Polyborosiloxane) and Silicon Carbide for the analysis.
