Denomination Magnetism Aided Machining (MAM) comprises a number of relatively new industrial machining processes (mainly finishing and surface improving) developed presently, too. MAM is effective – among others – for polishing, deburring and burnishing of metal parts. The magnetic force makes these processes simpler and more productive. Machining force is generated by an adjustable electromagnetic field between two magnetic poles within the working area ensuring the necessary pressure and speed difference between the tools (abrasive grains, pellets or rollers) and the workpieces. The authors give a brief outline of these modern processes. The paper summarizes the results of the experimental research carried out by the authors mainly in the field of Magnetic Abrasive Polishing (MAP) and Magnetic Abrasive Barrel Deburring (MABD).
