Bending method and bending system

This bending method is a method for bending a workpiece by means of a bending system provided with: a bending machine provided with a mold having a punch and a die which are provided so as to be capable of moving relative to each other; the manipulator is used for positioning a workpiece relative to the metal mold; and a control device for controlling the bending machines and the robot to perform bending, the bending method including a reset step for resetting the bending machines and the robot during the automatic operation of the bending of the workpiece by the bending machines, and the reset step for resetting the bending machines and the robot in the automatic operation of the bending of the workpiece by the bending machines. The press-in amount of the punch relative to the die or the origin position of the punch is reset for each predetermined trigger condition. 弯曲加工方法是通过弯曲加工系统进行工件的弯曲加工的方法，弯曲加工系统具备：具备金属模具的弯曲加工机，该金属模具具有被设置为能够相对移动的冲头和冲模；机械手，其对于所述金属模具将工件定位；以及控制装置，其控制这些弯曲加工机和机械手来进行弯曲加工，所述弯曲加工方法包含重新设定工序，在该重新设
