  • Patent number: 11904400
    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. When the current flows through the loop, an electrochemical hydrogen evolution reaction (HER) occurs at the micro-grinding tool in the grinding fluid, which generate multiple hydrogen bubbles. The bubbles coalesce into an insulating gas film and separate the micro-grinding tool from the grinding fluid; when the critical voltage is reached, the gas film is broken down and an electrochemical discharge occurs accompanied by discharge spark; under the action of the discharge spark, the surface material of the workpiece in the discharge-affected region is directly ablated to generate a heat-affected layer (HAL), namely, physical modification.
