Abstract

Abrasive flow machining is a process that involves material removal from the workpiece by the flow of a viscoelastic abrasive-laden polymer based compound through a restrictive passage formed by the workpiece with the tooling. This paper presents a simulation model to determine the characteristics of the media flow during machining and its experimental verification. The simulation model is developed using constitutive equations of Maxwell model describing non-Newtonian flow characteristics of the AFM media through cylindrically drilled workpieces. The flow characteristics like media pressure and machining characteristics like change in workpiece diameter are obtained experimentally and compared with simulation results. The graphical and statistical analysis of the shear stress output from the simulation and the corresponding values of the change in the diameter of cylindrical workpiece reveal a significantly consistent relation between the two, independent of the initial workpiece characteristics, thus validating the model.
