A magnetic polishing machine includes a container which accommodates a polishing target and a plurality of polishing pieces, a plurality of rotation plates which are rotatably disposed below the container while a magnet is attached to the rotation plate, and a first rotation mechanism which rotates each rotation plate about a rotation axis of the rotation plate. The adjacent rotation plates are disposed at a position in which rotation areas thereof partially overlap each other.

A process for support material removal for 3D printed parts wherein the part is placed in a media filled tank and support removal is optimized in a multi-parameter system through an artificial intelligence process which may include, but is not limited to, the use of historical data, parametric testing data, normal support removal data, and outputs from other support removal AI models to generate optimally efficient use of each parameter in terms of pulse repetition interval (PRI) and cycle time as defined by pulse width (PW). The input parameters may include heat, circulation, ultrasound and chemical reaction, which are used in sequence and/or in parallel, to optimize efficiency of support removal. Sequentially and/or in parallel, heat, pump circulation and ultrasound may vary in application or intensity. Selection of means of agitation depends on monitored feedback from the support removal tank and application of a statistically dynamic rule based system (SDRBS).

A method for outer surface finishing of a workpiece may include coaxially placing the workpiece inside a vessel. The exemplary vessel may include at least one baffle that may radially extend from an inner wall of the vessel toward the outer surface of the workpiece. The exemplary method may further include pouring an abrasive medium inside the vessel, rotating the abrasive medium about the longitudinal axis in a first direction within the vessel relative to the outer surface of the workpiece by rotating the vessel about the longitudinal axis, and concurrently rotating the workpiece within the vessel about the longitudinal axis in a second direction, the second direction being opposite the first direction.

A controllable magnetic field-assisted finishing apparatus for an inner surface and a finishing method are provided. The apparatus includes a housing, ball screw mechanisms, a workpiece, a centering clamp, a connecting plate, a magnetic field generating device, a chuck clamp, a precise displacement platform and a base. The magnetic field generating device includes electromagnetic coils, coil connecting plates, a magnetic yoke, nuts, springs and bolts. The magnetic field generating device dynamically adjusts a distance from the magnetic yoke to the outer surface of the workpiece through the springs. The movement tracks of the magnetic finishing medium are controlled by the formed rotation of the magnetic field, the finishing action force dynamic-adjustment, the optimization of the machining form of the magnetic finishing medium in collaboration with the rotation of the chuck clamp and the feed movement of the precise displacement platform.

A 3D magnetorheological polishing device and a magnetorheological polishing fluid are provided. The 3D magnetorheological polishing device includes a container and a magnetic field generator. The container is disposed with an accommodation space to accommodate a polishing fluid and a workpiece that is to be polished. The container is disposed on the magnetic field generator and rotates synchronously with the magnetic field generator. The container and the magnetic field generator are capable of rotating in conjunction at a predetermined speed, such that the polishing efficiency is improved.
