Fabrication of Micro-Dimple Arrays by EMM and RUREMM on Cylindrical Surface

To achieve high precision, stability, and good surface quality when producing micro-dimple arrays on cylindrical surfaces, we propose a new processing method known as radial ultrasonic rolling electrochemical micromachining (RUREMM) in this study. This is based the (EMM) machining principle. The relevant simulation model was created, ANSYS researched flow field characteristics of electrolyte between array electrodes workpiece. Micro-dimple were created SS304 with consideration effects parameters, including amplitude applied pulse voltage. Compared EMM, average width micro-dimples reduced by 24.5%, aspect ratio dimple increased 108.0%, roughness decreased 59.7%. In addition, localization RUREMM can be improved using appropriate parameters.
