Abstract

A novel polishing method is proposed to increase material removal rates through the acceleration of abrasive movements using micro-jets formed by spontaneous collapses of bubbles due to the cavitation in a special-shaped Venturi tube. The Venturi structure is optimized by numerical simulations. Process-related parameters for the optimal cavitation ratio are investigated for achieving maximum adaptation to polishing flat workpieces. Furthermore, this novel approach enhances processing efficiency by approximately 60% compared to traditional abrasive flow polishing. The processing method that employs cavitation bubbles within a special-shaped Venturi tube to augment the flow of abrasive particles holds significant potential for material polishing applications.

摘要

提出了一种新型抛光方法，通过利用特殊形状文丘里管内的空化作用使气泡自发坍塌形成微射流来加速磨料运动，从而提高材料去除率。通过数值模拟对文丘里结构进行了优化。研究了实现对平面工件最大适应性的最佳空化比的工艺相关参数。此外，与传统磨料流抛光相比，这种新方法可将加工效率提高约60%。利用特殊形状文丘里管内的空化气泡来增强磨料颗粒流动的加工方法在材料抛光应用中具有巨大潜力。
