Research On 3D Technology Of Small Size Of Electrolyte Jet Machining

With the rapid development of science and technology, many new products trend to precision and miniaturization direction development. The principle of the electrolyte jet machining is anodic dissolution of metals. It is based on the ion to remove from the material. This processing is a kind of "cool" method, and after the processing, the surface of the metal have no recast layer. The other traditional processing methods have no this feature. Hole processed with this method without burrs, without cutting stress and hardening. Therefore, the processing method has a great development prospect in micro manufacturing field.In this paper, we improve the filter and the working table of the test principle prototype. Improve the filtering accuracy of filtration system, make the filtering precision can reach 0.02mm, reduces the movement speed of working table, make the worktable velocity from 0.85mm/s to 0.4mm/s. Through a lot of experiments, we summary and analysis the processing law of electrolyte jet machining. The first is to study the narrow groove processing. By changing the table relative to the movement of the nozzle cycles, summed up the narrow groove processing technology rule. The test results show that with the cycle number increases ceaselessly, groove depth and removal is increasing in volume, and the slot width is only in a small range of variation. At the same time, we also design the single factor experiment; research the effect of the parameters on the hole. In this paper, the main parameters we studies are processing time and cathode distance. Through the experiment we found that when the processing time is 10 minutes, the current density is relatively large, and the current is stability, the morphology of the hole after processing is good, and the deep of the hole is large too. This paper has also carried on the experimental design. We explore the effect of voltage, frequency and the cathode on the hole depth and removal through the design of orthogonal test. The test results show that the voltage, frequency and cathode distance have effect on the hole deep. When the voltage is increased, the hole increases, at the same time, the hole is deep when frequency is high. If you want to get the deep holes, cathode distance should be choose 25mm. But on the study of the removal rate, we get that only voltage has effect on removal.This paper is researched the technology rules of the hole and narrow groove of the electrolyte jet machining through experiment, for researching 3D shape processing foundation.
