Abstract

AbstrakThis study aims to identify the springback problem in the OP20 bending operation of the Striker Read Seat Back 63332–68P30 component for Suzuki vehicles at PT. XYZ and to examine die insert radius adjustment as a corrective action. A descriptive case study was conducted using observations and interviews reported during an industrial placement, a review of technical documentation, and comparison with the literature. The documentation specifies SS400 material with an 8.0 mm stock diameter, OP10 forming and OP20 bending operations, and an inspection tolerance of ±0.5 mm using a checking fixture. For OP20, the report describes widening using values of 0.5–2.5 mm and identifies a reduction in the die insert radius as the corrective action. However, these values are not accompanied by a definition of the measured dimension, individual specimen data, initial and final radius values, or post-correction measurements. Consequently, neither the magnitude of dimensional improvement nor post-modification tolerance compliance can be quantified. This study maps the OP20 problem, the rationale for tool geometry correction, and the dimensional verification requirements. Further evaluation should compare measurements before and after modification using the same dimensional reference and forming conditions.Keywords: springback; OP20; die insert radius; SS400; dimensional inspection.
