Automatic sheet metal designing and processing method, device, control equipment and system

The invention relates to the technical field of automatic sheet metal machining, in particular to an automatic sheet metal designing and machining method, device, control equipment and system.The method comprises the steps that a three-dimensional design drawing of a workpiece to be machined is generated based on a three-dimensional reference drawing, the bending size, the forming size and a preset automatic mapping rule; checking the three-dimensional design drawing; if the verification is passed, performing expansion programming based on the three-dimensional design drawing to generate programming information, so that the production equipment can call the programming information to perform production processing to obtain a processed workpiece; automatically detecting whether the machined workpiece is matched with the three-dimensional design drawing or not; if the machined workpiece is matched with the three-dimensional design drawing, it is indicated that production of the machined workpiece is completed.
