Studies of Micro-Hole Burr Improvement for Aluminum Alloy Materials Using Vibrated Abrasive Grinding Machining

Abstract

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 burr was uniformly removed as the workpiece is fixture with vertical direction. In addition, the burr 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 determined by the material properties and the hardness of the abrasives.

Research on Aluminum Alloy Materials and Application Technology for Automotive Lightweighting

“…For every 1 kg reduction in the weight of the wheel hub, the car's fuel consumption can be reduced by 800 kilometers per liter of gasoline, thereby reducing fuel consumption and carbon emissions, achieving low-carbon environmental goals. Furthermore, aluminum alloy wheel hubs have good corrosion resistance and durability [8].…”

An experimental investigation of abrasive suspension flow machining of injector nozzle based on orthogonal test design

“…However, these studies only focused on the influence of a hybrid machining process on material removal rate and surface roughness, without considering the change in the flow coefficient caused by the change of microvariations after grinding. Other researchers [11][12][13][14] developed several hybrid machining processes in which various machining processes were combined with the AFM process to achieve a higher material removal rate and reduced surface roughness in a shorter time.…”
