Electrochemical mill-grinding (ECMG) is a new method of compound machining inspired bynumerical-control milling. A simple rodlike grinding wheel that rotates at high speed is used as thecathode and processes the workpiece along a set trajectory. Electrochemical milling and grinding areboth at play in ECMG, making it possible to machine large amounts of material from the workpiecewhile benefitting from excellent machining flexibility. In this paper, to machine GH4169 alloy highlyefficiently, four types of rodlike grinding wheel are designed, all with a diameter of 10.2 mm, and themachining flow field is simulated using ANSYS software. The maximum feed rate of each grindingwheel is measured under different values of voltage and electrolyte pressure, and a groove-machiningexperiment is performed in which a maximum feed rate of 2.3 mm/min and material removal rate of25.883 mg/s are achieved for a cutting depth of 10 mm. The machining accuracy and surface quality ofthe grooves are then compared and analysed.
