Abstract

The sheet metal forming process is one of the commonly used manufacturing methods in the manufacturing industry. It produces values such as effective plastic strain, effective stress, and springback, which are important parameters in assessing the quality of sheet metal. These values are influenced by several key parameters, including dies radius, pressing depth, and punch speed. The material used in this study is Steel Plate Hot-rolled (SPHD). This study aims to evaluate the quality of stress, strain, and springback in the work material resulting from the variation of these three parameters. The sheet metal forming process of v-bending method was carried out using simulation software by varying the dies radius between 89o, 90o, 91o and press depth of 7.7, 7.8 and 7.9 mm. From the simulation results of the v-bending method, the lowest effective plastic strain and effective stress values were obtained at a dies radius of 90°, a press depth of 7.7 mm, and a punch speed of 38.5 mm/s, with an effective plastic strain value of 0.39, an effective stress of 410.16 MPa, and an angle of 89.47°. The sheet metal forming process of u-bending method was carried out by varying the pressing force of 19.69 kN, 21.08 kN, and 21.88 kN. From the u-bending simulation results, the lowest effective plastic strain and effective stress were obtained at 19.69 kN with the lowest average effective plastic strain and effective stress values of 0.23 and 274.68. This shows that these parameters have an influence on the values of effective plastic strain, effective stress, and springback.
