Recent advances in ultraprecision abrasive machining processes
Abstract. Traditional approaches to understanding ultraprecision machining processes such as grinding, polishing, lapping, micromachining, machining, etc., have focused on developing analytical, semi-empirical and empirical models that seek to explain the output of processes based on many input variables. However, those models are not A magnetic abrasive finishing process using an alternating magnetic field is proposed for the finishing of complex surfaces. In an alternating field, the periodic changes in current will cause the magnetic cluster used as a magnetic brush to fluctuate, which will not only continuously replace the abrasive particles in contact with the workpiece, but Investigation of the application of a magnetic abrasive finishing
