Abstract
Aluminum alloy with high malleability is used for weight-saving in automobiles and airplanes. Therefore, the processing of aluminum alloy machine parts requires grinding to produce high-quality surface characteristics and high dimensional accuracy. However, application of grinding to materials with high malleability, such as aluminum alloy, tends to result in loading of the grinding wheel. At present, grinding wheels with large-sized abrasive grains are used for the grinding process. This study was carried out to investigate the effects of ultrasonic vibration grinding on the aluminum alloy, by vibrating the grinding wheel at 30 kHz in the radial direction. Moreover, the effectiveness of ultrasonic vibration grinding was studied. The results indicated that ultrasonic vibration grinding could yield improved surface quality, with reduction of roughness, waviness, and loading.
