ECM machining of curvilinear rotary sufraces

The paper deals with a theoretical analysis of curvilinear rotary surface machining (ECM) by a shaping electrode tool. An equation describing the curvilinear rotary surface shape evolution, and an equation of the electrolyte and gas mixture flow through the gap between curvilinear rotary surfaces, have been formulated. Calculations have been performed for the assumed machining parameters, depicting calculation results along the interelectrode gap. Distributions of: gap thickness, current density, void fracture, temperature, electrolyte flow rate and pressure have been presented in charts.
