摘要：
A sheet metal component that is bent from a sheet metal blank includes at least one three-sided corner. Two edges of the three-sided corner are formed by a first bending member of the sheet metal blank bent about a first inner bending radius Ri,1 and a second bending member of the sheet metal blank bent about a second inner bending radius Ri,2, and the third edge of the three-sided corner is formed by a first blank edge of the first bending member and a second blank edge of the second bending member. The sheet metal blank has an internal corner that forms the first blank edge, the second blank edge, and a wedge-like recess that opens in the internal corner.
