Research on Servo Control System for Synchronous Double-wire Electrode Micro EDM
A synchronous differential feed double-wire electrode micro EDM method was proposed,which improved machining efficiency by synchronously discharging both sides of the dual electrode.At the same time,the dual side discharge heat source can effectively reduce the deformation of thin-walled parts.A machining device and servo control system were designed and developed to implement this method.PMAC motion control card and FPGA were used in conjunction to control the servo motion of the workpiece feed module and machining module,and synchronous discharge of dual electrodes was achieved by utilizing dual independent TR pulse power supply.By comparing the use of single wire electrodes and double wire electrodes cutting spring steel sheets with a thickness of 0.5 mm respectively,the results show that double wire cutting has a significant improvement on the bending deformation phenomenon of thin-walled parts compared to single wire cutting.
