Dynamic simulation and experimental verification for edge quality improvement in rotational electro-magnetic finishing process

A rotational electro-magnetic finishing (REMF) was an effective way to minimize burr and improve edge quality on the surface. This study conducted two stages of explicit dynamic simulations: signle collision analysis and multiple collision analysis to verify the effect of abrasives’ behavior on the deburring processes. From observed results, successful deburring depended on the total amount of abrasives and the collision angle. Based on the simulated results and response surface methodology, it was found that the accuracy was reached approximately 95.4 %. Additionally, the maximum deburring area from the predictive model and simulation were similar to 2.27 mm 2 and 2.37 mm 2 , respectively, at rotational speed of 1800 rpm, abrasive diameter of 0.7 mm, and abrasive weight of 2.0 kg. In the experimental verification, the results were in good agreement with the experimental data, although specific values did not correspond exactly. Thus, the suggested approach adopting explicit dynamic simulations could effectively evaluate deburring performance in the REMF process.
