Description
Technical Field
The invention relates to the technical field of electromachining, in particular to a novel electrode composite electromachining device and a processing method.
Background
Compared with the traditional metal material, the metal-based composite material has higher rigidity and strength; compared with silicon carbide-based materials, the toughness and impact performance are higher. Among metal matrix composites, the most widely used is an aluminum matrix composite, the particle-reinforced aluminum matrix composite is a composite in which aluminum or aluminum alloy is a continuous phase and ceramic particles are a second constituent phase, and the performance of the aluminum matrix composite depends on the characteristics, content, distribution and the like of the matrix alloy and the reinforcing phase. Aluminum matrix composites have many superior properties compared to matrix alloys.
The excellent properties of the metal matrix composite, which are different from the physical properties of the reinforcing phase and the metal matrix due to the composition and even stronger than the composition, determine that the metal matrix composite is an ultra-difficult-to-process material, especially the aluminum matrix composite is a typical material with high hardness, high strength and difficult to cut, and the processing becomes increasingly difficult with the increase of the reinforcing phase fraction and the increase of the ceramic particles, especially the difficulty of secondary processing is a bottleneck problem limiting the industrial application. The conventional processing method mainly comprises mechanical cutting processing, and the special processing method mainly comprises abrasive water jet processing, laser-assisted micro-cutting processing, ultrasonic-assisted grinding processing, electric spark grinding processing and electrochemical discharge processing, wherein the processing mechanisms of the special processing method are different and have respective advantages and disadvantages.
Although the processing speed of the electric discharge machining method is relatively low, the machining precision of electric discharge forming and electric discharge wire cutting is relatively high, and a complex geometric structure can be processed, so that the electric discharge machining is a relatively effective metal matrix composite material processing method at present, and researchers have conducted a great deal of research on the electric discharge machining technology of the particle reinforced metal matrix composite material. In the process of processing the metal matrix composite material by adopting the electric spark processing technology, on one hand, the ceramic particles with high melting point are difficult to vaporize or melt in the processing process due to the very high melting point of the ceramic particles in the material, and the ceramic particles with high melting point are continuously aggregated on the processing surface along with the processing, so that the abnormal arc discharge phenomenon is caused, the electrode is damaged, and in addition, the surface quality of the workpiece processed by the electric spark is difficult to meet the actual requirement.
In particular, the particle-reinforced phase in the material is generally insulating particles such as ceramic or silicon nitride, and the material has a high melting point. Therefore, the particle phase is difficult to remove in a form of vaporization or melting in the processing process, but along with the processing, the particle materials of the reinforcing phase are continuously accumulated in the gap and are difficult to discharge from the processing gap, so that abnormal electric discharge processing phenomena are easy to cause, and the problems of poor processing quality, low processing efficiency, large electrode loss and the like are caused.
Researchers have designed novel tool electrodes such as grooving, edging, hollow and polygonal, and have attempted to promote the discharge of debris such as reinforcing phase particles, improve the machining efficiency of machined particle-reinforced metal matrix composites, improve the machining quality, and reduce the electrode loss by various methods of electric discharge machining, but the machined surface quality is not ideal.
When the traditional machining is used for machining the particle reinforced metal matrix composite, the cutter has large loss, and frequent replacement of the cutter easily causes the problems of low machining efficiency, high cost and the like. In addition, tool electrodes such as grooving, edging, hollowing, polygonal and the like are adopted, and the discharge of the particle reinforced phase can be promoted to a certain extent when the particle reinforced metal matrix composite material is processed by electric spark. However, in actual electric discharge machining, although the grain phase size varies and the electrode such as a groove, a chamfered edge, or a polygon can promote chip removal, the surface quality of machining is not satisfactory.
