Indentation of punch, beating angle and beating pitch are dominant factors for incremental in-plane bending process. In this paper, the effects of beating pitch on beating force, bending radius and strains in the three directions are clarified by finite element analysis and experiment. The results show that the beating pitch has no effect on bending radius when the actual indentation is same. On the other hand, when the setting indentation is fixed, the beating pitch has an effect on bending radius due to the elastic deformation of punch and the support part. These forming properties of in-plane bending obtained by analysis and experiment had an agreement.
