Abstract

The present invention relates to a method for feeding magnetic material in a stream, where the magnetic material is singulated one after the other in a feed path where a series of electromagnets are provided along the feed path to provide a series of magnetic fields to direct the magnetic material to the required location and direction. The method can be used to perform operations on the workpiece by interacting the object with the workpiece as an individual tool, including sorting, shaping, material removal, physical modification, chemical modification, material addition, cutting, grinding, abrasion peening, and energy addition. Lubricant / purge materials are fed to the workpiece and arrive at different times relative to the tool.
