Research on bending and roll-bending （BRB） of plate is the base of designing roll-bending equipment parameter, BRB processing parameters and achieving automatic control of BRB process. The development status of plate BRB process at home and abroad is discussed from the aspects of modelling method, model accuracy and applicability, etc.. The influencing factors of the BRIg models are summaried from five aspects such as material characteristics, BRB process flow and springback. The develop- ment status of auto-controlling BRB model is reviewed. The future research direction and development trend of plate BRB are forecasted.
