FINISHING TECHNIQUE

摘要

Various methods and systems are provided for finishing a target surface. In one embodiment, a arrangement includes a target surface; at least two electromagnets; a magnetic abrasive fluid mixture disposed on the target surface; and at least one time varying electrical signal driving the electromagnets to cause each of the electromagnets to generate at least one time varying magnetic field, thereby agitating the magnetic abrasive fluid mixture. In another embodiment, a method includes placing a magnetic abrasive fluid mixture on a target surface; positioning a pole tip of an electromagnet in a predefined position relative to the target surface; and driving the electromagnet with a time-varying electrical signal to cause the electromagnet to generate a time-varying magnetic field, thereby agitating the magnetic abrasive fluid mixture.
