A method for determining hammering sequences in incremental forming of sheets is proposed on the basis of the genetic algorithm. The determination of the sequence for forming a sheet into a desired distribution of curvature in incremental forming is treated as a combinatorial optimization problem. The sheet is modeled to have many numbered points worked with a hammer, and is deformed under a constant load. In the genetic algorithm, a group of individuals having a combination of hammering points is set, and the combinations are optimized by selection, crossover and mutation operations in order to minimize the difference from the desired curvature distribution. The hammering sequences in incremental forming of aluminium square sheets with a hemispherical punch and a flat die are chosen as an example.
