초록
In this paper, arbitrary pulse power for electro chemical etching, which manufactures the groove of fluid dynamic bearing and aero dynamic bearing, is presented. For high precision manufacture, we generally use high precision CNC machine. However, this case has the disadvantage that cost is very expensive and bur due to bites of tool can be generated. So most of companies are interested in the method of electro chemical etching. But for more precision results, it is important to decision the parameters of electrical conditions, such as currents and frequency. We designed and made the arbitrary pulse power system easy to input the parameters for optimal conditions. Experimental results show the effectiveness of the system strategy proposed for the high precision manufacture.
