STUDIES OF MICRO-HOLE BURR IMPROVEMENT FOR ALUMINUM ALLOY MATERIALS USING VIBRATED ABRASIVE GRINDING MACHINING

摘要

This study investigated the removal improvement of micro burrs of aluminum alloy materials using vibrated abrasive grinding machining. The image processing technology is used to examine and quantify the micro-hole burr profiles. The experimental results show that the micro bun-was uniformly removed as the workpiece is fixture with vertical direction. In addition, the bun-removal improvements are effectively influenced by the flowing velocity and the vibration energy of abrasive particles. The flowing velocities are dependent on the size and gravity of the abrasives and the vibration energy is detennined by the material properties and the hardness of the abrasives.
