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.

Abstract: An electrolytic machining system includes a controller, a drive member coupled to the controller, a power supply, a diving circuit, a detecting circuit, and an electrode module. The diving circuit is coupled to the power supply module and configured to divide a total voltage taken from the power supply module into a plurality of independent working voltages. The detecting circuit is coupled to the dividing circuit and the electrode assembly. The detecting circuit detects each independent working voltage and feeds back information as to the level of the independent working voltage to the controller as the electrode assembly is moved towards a workpiece. When the detection indicates an incorrect working voltage, the controller controls the drive member to move the electrode assembly away from the workpiece.

Abstract: An electrochemical machining apparatus is modular and includes a power module, an electrolyte processing module, an actuator module, and a control module that are connected with one another via a connection apparatus. The components are modular and are mounted on separate supports, many of which additionally include caster, and the connection apparatus is in the form of a removable umbilical. The modules can be individually moved to a location within a facility where a component is installed, and the modules can be interconnected to form the modular electrochemical machining apparatus at the location of the installed component. The apparatus can then perform an electrochemical machining operation in situ on the installed component.
