Modelling of centrifugal-force-assisted abrasive flow machining

Centrifugal-force-assisted abrasive flow machining (CFAAFM) process has recently been tried as a hybrid machining process with the aim towards performance improvement of the abrasive flow machining process by applying centrifugal force on the abrasive-laden media with a rotating centrifugal-force-generating rod introduced in the workpiece passage. In the CFAAFM process, the surfaces are generated by erosion from random attack of abrasive particles. This article deals with the theoretical investigations into the mechanism of material removal in the CFAAFM process. Analytical model is developed to estimate the material removal during the process. A good correlation is found to exist between the theoretical results and the experimental data.
