Abstract

The invention relates to the technical field of workpiece cutting, in particular to a method for cutting a conductor material. The purpose of the invention is to solve the problem that the surface quality of a cut workpiece is not high in the existing electric spark cutting technology. In order to achieve the purpose, the invention provides the method for cutting the workpiece; and low-resistivitydeionized water is used as an electrolyte, and two electrode wires are used for cutting the workpiece at the same position. According to the method, an anode dissolving principle is introduced into the electric spark cutting technology, so that re-cast layers on the surface of the workpiece subjected to electric spark cutting can be removed, and the surface quality is improved. The method is suitable for cutting all conductive materials, and is wide in application range.

Description

technical field [0001] The invention relates to the technical field of workpiece cutting, in particular to a method for cutting conductor materials. Background technique [0002] In the cutting technology of conductor materials, wire electric discharge cutting (WEDM) is a common cutting technology, which is widely used in engineering. Since the tool (electrode) and the workpiece do not need to be in contact during the processing process, there is no contact force generated, and the hardness of the workpiece can be ignored when cutting the workpiece. Difficult-to-machine materials such as high alloys. [0003] EDM is based on thermoelectric energy between the electrode and workpiece. During processing, there is a small enough gap between the workpiece and the electrode so that the pulse voltage between the workpiece and the electrode can ionize the electrolyte, and a short pulse discharge is generated in the electrolyte in the gap, through melting and gasification Erosion ...
