  • Magnetic abrasive finishing of curved surfaces
    Patent number: 11440156
    Abstract: A system for magnetic abrasive finishing of a workpiece may include a magnetic abrasive brush that may include a plurality of magnetic/abrasive particles and an electromagnet configured to apply a magnetic field on the plurality of magnetic abrasive particles. The system may further include a first actuating mechanism that may be configured to actuate a rotational movement of the workpiece about a longitudinal axis of the workpiece, a second actuating mechanism that may be configured to actuate a linear movement of the magnetic abrasive brush along a first direction relative to the workpiece, the first direction parallel to the longitudinal axis of the workpiece, a sensor coupled to the magnetic abrasive brush that may be configured to measure a working gap between the magnetic abrasive brush and an outer surface of the workpiece at any given instant.
