Abstract: This paper describes an invention involving an electrochemical discharge-enabled micro-grinding process for micro-components of silicon-based materials. The specific machining method is described below. A micro-grinding tool and an auxiliary electrode are respectively connected to the negative and positive electrodes of a pulsed DC power supply.
