In numerous non-traditional, micro-machining, the electrochemical micro-machining ( abbreviated as EMM ) has the advantage of quick processing speed, good convergence in surface stress , and nice smoothness in workpiece surface with enormous potentialities and highly added value.
A copper tube with 300 - micron meter of diameter is selected as electrode tool. The inner flowing vein, pulse power supply which supplies a regular intermittent power to machine the product intermittently, and with the water flowing sidelong are employed for improving the precision of products and increasing the depth –width ratio. In this research, Single Variable Method is used to analyze the influence level on the hole diameter of workpiece by relevant parameters ( such as voltage, duty, pulse period, density of the electrolyte, and feed rate).
Finally, we take the best parameters to machine the depth of 5600 micron - meter then we obtain about 900 micron - meter of hole diameter
and 6.2 depth-width ratio. | en_US |
