The effectiveness of integrated control on parameters in electrochemical grinding (ECG) determines the precision and efficiency of its machining to great sense. In order to achieve efficient integrated control of electrochemical grinding parameters of motion, electrolyte and power supply, a NC embedded PC open integrated control system was developed. Firstly, according to the characteristics of ECG, the overall design requirements for integrated control system for ECG machine tool were analyzed, and then on the basis the overall scheme was designed. The hardware structure was presented, which applied multifunction motion control card and versatile data acquisition card as the control center, industrial panel PC for the platform of human computer interaction. At the same time, hierarchical modular software was designed by using Visual Basic, and functions of human computer interaction, automatic control and monitoring protection were realized. Results of machining example show a high quality flat can be machined successfully on the inner wall of micro-scale multi-grooves of parts by this integrated control system.
