Description

technical field [0001] The invention relates to the technical field of numerical control, in particular to a method for cutting steel plate bevels based on visual recognition. Background technique [0002] Components of metal structures are usually tailor-welded from multiple steel plates. After each steel plate is cut and blanked, according to the requirements of structural calculations, grooves need to be made around some of the parts in order to improve the bearing capacity of the components after welding. In terms of production cost and efficiency, artificial flame cutting is the most common way to process the groove around the steel plate. [0003] After the popularization of CNC cutting technology, the steel plate parts should be able to realize the cutting and forming of the groove at the same time theoretically after CNC cutting and blanking according to the requirements. Affected and unable to achieve a good cut. Therefore, in fact, the groove forming production n...
