The cutting method is a cutting method for cutting a workpiece using a wire tool, including: supplying a slurry containing abrasive grains having an electrical dielectric property to a region of the workpiece into which the wire tool cuts; generating an alternating electric field in a region between the wire tool and the workpiece; and running the wire tool along a direction in which the wire tool is drawn while the wire tool abuts on the workpiece.

A polishing method with a polishing apparatus includes an electrode constituted as a plurality of electrode elements, a device of driving the electrode, and dielectric abrasive particles disposed between the electrode and a workpiece. Polishing pressure is applied to the particles by a Coulomb force generated when an alternating-current voltage is applied to the electrode.
