Abstract
Fine-blanking as an effective and economical sheet metal cutting process has been widely used in the precision machines, automobiles, electronics and aircraft areas. This process can produce smooth-sheared edges over the full workpiece thickness in one single operation with the optimized process parameters. However, the crack phenomenon always occurred in the fine-blanking process when the part shape is complicated. The forming quality of the part with concave and convex shape has been investigated with finite element simulation and experiment methods. In order to reveal the effect of part shape on the fine-blanking process comprehensively, a simple finite element model in which the part has convex and concave shape were created. The effects of the angle between the neighbouring edges and height of the convex and concave on the surface quality have been investigated. Furthermore, the way to design the parameters for parts with complicated shape has been discussed in this paper.
