Research on Percussion Incremental Forming Performance of AA2024 Aluminum Alloy Sheet
In order to explore the appropriate range of NC incremental forming process parameters and determine the better percussion incremental forming performance scheme,by single factor test method,explores the influence of amplitude,frequency,tool head diameter and layer feed on pageon AA2024 aluminum alloy sheet metal forming performance.The experimental results show that compared with the traditional incremental forming method,the percussive incremental forming method can reduce the forming limit angle and the forming property of the sheet metal.When the amplitude is 5 mm,the forming limit angle increases with the increase of frequency.When the amplitude is 10 mm,the forming limit angle decreases with the increase of frequency,the forming increases with the increase of layer feed,and decreases first and then increases with the increase of layer tool head diameter.
