Abstract
Blasting erosion arc machining (BEAM) is a novel and promising electrical machining process for difficult-to-cut material processing. In this research, air is applied as an alternative dielectric to investigate the feasibility of dry BEAM. An arc plasma observation experiment is designed and conducted based on a four-channel intensified charge-coupled device (ICCD) high-speed camera in order to observe and investigate the arc plasma expansion and deflection behavior. Furthermore, the influence of the aerodynamic force on plasma column deflection is also studied through comparing the images under different airflow velocities. Voltage and current waveforms were captured to verify the positive effect of air flushing on plasma channels’ deflection behavior. Additionally, crater geometries on the workpiece and electrodes were also observed and discussed as a means to analyze the effect of airflow on machining characteristics. The experimental results reflected that aerodynamic arc disturbing mechanism can be realized in air flushing BEAM, which is a promising process of working fluid for BEAM.
