摘要：

Incremental rolling technology is a process of rolling microgroove structure on sheet metal surface by incremental forming. Based on the principle of the process, the traditional single roller profile was designed into four kinds of roller profile, and the incremental rolling process of the new roller profile was simulated by finite element software. Then, the forming quality of the new roller profile was compared with that of the traditional roller profile, and the material flow characteristics of workpiece during the rolling process of the new roller profile were analyzed. The results show that the microgroove height of the new roller profile is equal to that of the traditional roller profile after rolling, but the accumulation at the end of workpiece formed by the latter is less than that of the former. However, the forming load of the new roller profile is smaller. Furthermore, the flow characteristics of workpiece material during the forming process are obtained by the analysis of the velocity field, equivalent stress field and strain field of workpiece, which provides an effective reference for the optimization design of roller in the future.
