Abstract

With the continuous development of aeronautical an space technologies, greater demands are being placed on the aviation and aerospace engine performance. The machining accuracy of fuel injection micro hole has great influence on engine performance. The machining accuracy of micro hole is closely related to flow rate and other physical parameters, so the research and analysis on processing high-accuracy micro hole are of great significance. The thesis researches on the inaccuracy of micro hole’s machining straightness and cylindricity in the way of experimental study and analysis on micro EDM milling, optimization of electrical parameters, layered machining of tiny thickness and so on. The result shows that when the no-load voltage is 110V, the peak current is 70A, the pulse length is 4µs, the interval of pulse is 90µs, layered thickness is 0.15mm and the discharge gap is 0.012mm, micro hole’s milling gets the highest accuracy, and the range of dimensional accuracy processing is 0.005mm, the surface roughness is 0.427µm.
