Abstract

The invention discloses a multi-material electric spark processing electrode and a processing method thereof. The multi-material electric spark processing electrode comprises an electrode base and a component electric corrosion material arranged at the bottom of the electrode base; the component electric corrosion material consists of more than one electric corrosion material, the electric corrosion materials have different electric corrosion resistance degrees, and the electric corrosion materials and the electrode base have different electric corrosion resistance degrees; and when the electrode base and a workpiece are connected with the positive electrode and the negative electrode of a pulse power supply respectively, a superfine complex curved surface is formed on the surface of the bottom of the component electric corrosion material. According to the multi-material electric spark processing electrode and the processing method thereof, which are provided by the invention, the superfine complex curved surface is processed by an electric spark forming method, so the problems that the processing efficiency is low, electrodes are changed frequently and a tedious cutter track planning strategy needs to be adopted in the traditional layered milling processing method are avoided; and one-step formation of the complex structure can be realized, secondary clamping errors caused by electrode change are avoided, and high-efficiency forming processing of the superfine complex curved surface is realized accurately.

Description

technical field [0001] The invention relates to the technical field of fine and special processing, and is a multi-material electric discharge machining electrode and a processing method thereof which are applied in the electric discharge processing industry of fine and complex curved surfaces. Background technique [0002] Miniaturization, precision, and complexity are the important development directions of today's electromechanical products. In many technical fields such as aerospace, optoelectronic communication, biomedicine, and mold manufacturing, many key parts often have fine and complex surface features, and even involve free-form surfaces (such as complex housings of micro-aircraft, micro-precision optical devices, and complex micro-sensors). Due to the special requirements of application conditions and working environment, these key parts often use difficult-to-machine materials such as high-performance metal alloys and functional materials. [0003] At present, ...
