The invention discloses a pulse conduction and mechanical cutting combined processing method for a metal material, which comprises the following steps of: when a cutter is used for cutting metal, introducing a high-frequency pulse power supply into a cutting area (wedge-shaped area), and quickly raising the temperature of a material around the tip of the wedge-shaped cutting area due to an electromagnetic heat effect, so as to soften the material; and the hardness of a material in a cutting area is reduced, so that mechanical cutting becomes easy. The method comprises the following specific steps: mounting a pulse power supply on a machine tool and connecting with two ends of a workpiece to form a current loop; and then pulse power supply parameters are adjusted, and the metal workpiece installed on the machine tool workbench is cut. The conductive and mechanical cutting combined machining method for the metal material has the advantages that the production efficiency is high, the machining precision and qual
