PROBLEM TO BE SOLVED: To obtain the smooth progression of an operation and to improve the operating efficiency by deciding the bending order of a work and a die, displaying the information of change-movement for work posture so as to abut the work on the end part according to each process and bending based on this information. SOLUTION: A press brake vertically moves a lower table 1, to which the die 3 is fitted, with a cylinder 8. The information of a product is inputted in an input means 14. Each bending order of the work and the die 4 used at this time, are decided with a calculating and deciding means 9B based on the product information. Based on this decided bending order, the change-movement information for work posture is indicated so as to abut the work on the end part 3 according to each process by using an abut-driving control means 15 and an displaying means 16. Successively, based on the indicated change-movement for work posture, the bending is applied to the work W whose posture is changed with a control means 9A. In such a way, an operator can easily confirm the change-movement of the posture in the case of abutting the work on the end part.
