原始语种摘要: Abstract(#br)Abrasive flow machining (AFM) is considered one of the best-suited candidates for the finishing of complex components made by additive manufacturing. However, the AFM process leads to mass loss and consequent alteration of the part geometry and dimensions. A numerical tool is needed to reduce the number of time-consuming and labor-intensive experimental trials and allow the efficient prediction of machining allowances for the final geometry and surface finish of AFM-processed parts. This paper presents a combined numerical-experimental approach to predict the results of such a polishing process. The model devised simulates the indentation of abrasive grains to a workpiece and takes into account the initial surface roughness of the part as well as the velocity and pressure of...
