摘要

本研究利用振動研磨技術針對鋁合金材料微孔毛邊去除效果進行探討。實驗分成兩部分，首先藉由改變振動條件(頻率、振幅)、磨料種類、磨料粒徑等參數，探討6061-T6鋁合金表面微毛邊改善效果，實驗結果顯示，隨著頻率、振幅增加，磨料顆粒具有良好的流動性，能有效對鋁合金表面入口與出口毛邊進行去除；第二階段探討6061-T6鋁合金階級孔表面微毛邊改善效果，增加荷重磨料種類、磨料混合比例等參數，實驗結果發現隨著頻率、振幅的增加可有效提升荷重磨料研磨作用力，能有效去除鋁合金孔內微毛邊，未來更可應用至其它材質微孔毛邊改善。

Abstract

This study developed a vibrated grinding technology to improve the burr removal efficiency of micro-hole for aluminum alloy material. Experiment into two parts, firstly, the vibration conditions (frequency and amplitude), abrasive types and abrasive size are used to investigate the effect of burr removal of micro-hole for 6061-T6 aluminum alloy. The experimental results show that the abrasive’s flow ability increased with the vibrated frequency and amplitude. The burrs of micro-hole are effectively removed for the inlet and outlet of aluminum surface. The micro burr removal efficiency of micro-class hole is also investigated by changing the types of load abrasive particles and ratio of mixed abrasive particles. The experimental results showed that the burrs are effectively removed with the grinding force of abrasive particles. The vibrated grinding technology developed in this study can also be applied to the burr removal of other machining material.
