Magnetic damping in turning of stainless steel aisi 304 for the reduction of machining vibration and tool wear

Chatter is a type of intensive self-excited vibration commonly encountered in machining. It reduces productivity and precision, and is more noticeable in the machining of difficult-to-cut alloys like hardened steel. In such cases chatter causes excessive tool wear, especially flank wear, which in tu...
