Abstract:To achieve electrochemical machining machine tool automatic control and improve the machining precision, the control system was designed according to the complex parts control requirements of electrochemical machining. The main control system implemented the integrated control by using PC, DAQ card, motion card and other hardware, and the main control system software was designed by the software platform VB6.0, mainly including the design of the software control interface, servo drive parameters settings and the control program design on uniaxial and multiaxis movement, also manual processing, automatic processing ,fault diagnosis and other functions were added according to the practical application. Finally, to ensure the reliability and stability of the software, processing experiment based on the control system was used to evaluate the feeding and positioning accuracy of the tool cathode and the machining quality of the specimens. The experiment results show that the feeding and positioning accuracy of the tool cathode can be achieved ±0.005 mm and the dimension of slit width is 0.278 mm, which meet the requirements of the dimensional precision and reflect the control system with high reliability and good stability.
