Value Engineering of Micro-Manufacturing Using ECM and its Applications

In the experiment, typical results at the microscopic level, such as fine grating and micro indenting are demonstrated. It is suggested that a strategy of combining aspect in a centralized and distributed manner might be used to increase both productivity and flexibility in manufacturing. The current techniques for micro manufacturing mostly are silicon based. These manufacturing techniques are not suitable for use in demanding applications like aerospace, micro factory and biomedical industries. Micro-electrochemical machining removes materials while holding micron tolerance and µECM can machine hard a navel µECM utilizing high frequency voltage pulses and closed loop control. The work piece materials are used as “Coinage metals”. The research studied the effect of various parameters. The experimental data on small drilled holes agreed with theoretical modal burns can be effectively removed by optimal µECM. A sacrificial layer helped to improve the hole profile since. It reduced above 50% corner rounding. Its electrochemical manufacturing localization is closely related with accuracy and the accuracy will be improved when the localization is enhanced. Micro holes are electrochemical drilled in stainless steel using nanosecond pulse power, millisecond pulse power and direct current power. The experimental results show that the localization could be significantlyenhanced using nanosecond pulse power .
