Advanced precise electrochemical machining

Currently, electrochemical machining (ecm) does not allow for meeting the specifications prescribed in many high-tech applications for advanced materials. We will develop a new technological foundation for ecm that addresses these limitations.

BACKGROUND Electrochemical Machining (ECM) is an erosion process where an electrical current is applied between a vibrating electrode and the workpiece. The workpiece then dissolves in the narrow slit that separates it from the electrode. For many high-precision applications, ECM is the only economically viable machining technology. PROBLEM AND SCOPE OF THE PROJECT The current technological foundation of ECM does not allow the machining of advanced, hard alloys within the specifications required for high-technological applications (aerospace, medical applications, nano-technology, etc.). Extending ECM in this direction would enable the manufacture of products that cannot be conceived at present. This is the scope of the current project. It requires a radical departure from the current technology that defines a new process, Advanced Precise Electrochemical Machining (APEM). The main technological challenges lie in the development of technology for the generation and efficient transmission of electrical pulses of extremely high intensity and frequency.
