Each clamping mode is only suitable for one type of product, and for thin-wall parts with complex structures, a clamping mode of pressing by a pressing plate is mainly adopted, and the product has complex structures, so that the auxiliary support is inconvenient to operate, high in manufacturing cost and low in efficiency; the clamping deformation or the clamping looseness is easy to occur without auxiliary support. When the clamping force is too large, the product can be stressed and seriously deformed, the product quality is influenced, and the product is scrapped. When the clamping force is too small, the product can shift position during processing, so that the product is scrapped and even the cutter is damaged. Therefore, the clamping force is very difficult to control, and the product is deformed when the supporting strength of the product is reduced due to internal stress and product deformation in the processing process after partial materials are cut off, so that the product is easy to lose the clamping force, and the risks of product scrapping and cutter damage are greatly increased. At present, the situation of clamping failure is prevented from occurring mostly by using larger clamping force, and meanwhile, the rejection rate of the products is increased and the quality of the products is reduced due to overlarge clamping force.
