Precision cutting is a method used for the manufacture of sheet metal parts with narrow dimensional tolerances and where the cutting surface quality is desired to be much superior compared to conventional cutting methods. Sheet material properties and the design of the cutting die, ironing clearance and machining parameters are important factors in precision cutting of metals. In this study, the precision cutting and ironing process for the crank felt made of DC04 EN10130 cold rolled steel quality sheet metal with high impact resistance and strength, which is used in the production of automotive spare parts, was investigated by the finite element method. In the study, the simulation results with a cutting gap of 1, 3, 6 percent and a spinning ratio of 0.5, 7.5%, among the mold geometries designed for the target geometry, and the experimental results were in good agreement with each other.
