Electric Spark Milling Processing Applied Technology Research

Along with the science and technology rapid development, the new material is used unceasingly, is day by day complex to the product structure, more and more is also high to its precision and the product quality request, sometimes the traditional machine-finishing method very is difficult to be even unable to meet the actual processing requirements. In order to adapt this kind of development, the electric spark machining technology took one kind of advanced processing method to arise at the historic moment.This article embarks from the electric spark processing mechanism, takes the object of study by the electric spark mill processing, through experimental study in electric spark machining environment, various electrical parameters to craft target influence rule. At the same time, selects the most commonly used 45 steel to take the experimental work piece material, the tool electrode selects the red copper electrode, has carried on the craft experiment, the distinction experimental study single item parameter change to the craft target influence. This topic the engine bed handbook technological conditions number which was provided by the factory has also conducted the maintenance test research.Unified this laboratory four axis three linkage electrical discharge machine numerical control processing characteristic, the use simple shape electrode has carried on in the plane the cutting tool compensation quantity formulation and the computational method, as well as cutting tool radius compensatory function application experiment. Finally, the CAM module has produced the three dimensional die space processing knife position path based on UG NX in using the die space milling function, thus obtains in the electric spark mill processing the electrode path, then will process instruction which the electrical discharge machine will be able to distinguish, will use the red copper electrode, in 45 steel, has carried on the rough machining and half fine mill processing experiment to the die space.The electric spark milling processing has the big electrode loss. How to solve the electrode compensation problem to realize the electric spark milling is the key. The paper study the loss compensation which was discharged to the electrode end surface, confirmed the electrode end surface electric discharge compensation through the experiment is feasible, and the compensation to the lamination milling electrode lost to conduct in the theory research, lifted the knife to servo in the electric spark mill processing, lifted the knife the speed control as well as the die space processing precision assignment problem has conducted the research.
