The suspension system of an automotive vehicle plays a crucial role in ensuring stability, comfort, and safety. Among its key components, the front arm bush is significant, providing damping and isolation during energy exchange due to road irregularities in terms of forces and heat. This experimental investigation evaluates the performance of the SAE 1018 front arm bush, produced using a computer numerically controlled (CNC) turning center, under various manufacturing conditions. SAE 1018, a low-carbon steel with 0.18% carbon content, was chosen for its favorable mechanical properties. Critical process parameters, including speed (RPM), feed rate (mm/min), and solute chemical percentage, were analyzed for their influence on key responses such as material removal rate (MRR, g/s), surface roughness (Ra, micron), and ovality. A response surface methodology (RSM) design of experiments was employed, utilizing an L15 central composite design to determine the optimal number of experiments. RSM was further applied to model and optimize the process parameters, with the goal of enhancing the performance of the manufactured bush, particularly in terms of durability, vibration-damping properties, and its impact on vehicle handling and ride quality. The findings from this research aim to contribute to the improvement of automotive suspension systems, leading to enhanced performance and reliability.
