Abstract

Abstract: Rotational ultrasonic effects were integrated with multi-energy field systems of grinding, electrolysis effectively and discharge to achieve precision and high-efficiency composite multi-field processing of difficult-to-machine materials and complex shaped parts. Researching on the mechanisms of rotational ultrasonic composite multi-field processing. A rotational ultrasonic-compounded multi-field processing experimental system is designed and developed, which could realize multi-field machining experiments and parameter optimization involving grinding, ultrasonics, electrolysis and discharge. Experimental schemes are designed to conduct mechanical grinding, ultrasonic grinding and composite multi-field processing experiments on high-speed steel, aluminum, and SiCp/Al particle-reinforced ceramic materials. Tests proved that multi-field composite processing could effectively reduce mechanical forces and heat generation while enhancing grinding effects. Meanwhile, it ensured timely removal of inter-electrode materials and renewal of electrolytes to improve and stabilize electrolysis effects. Reasonable selection of multi-field synergy parameters can ensure processing accuracy and improve processing efficiency. After parameter optimization, a certain type of aero-engine blades meeting surface accuracy requirements are machined. The rotational ultrasonic composite multi-field processing method has the combined advantages of multiple technologies and has major engineering application prospects.
