Abstract: This article investigates the parameters affecting the roughness of surfaces produced during turning operation using a vibration isolating compliant damper. The vibration is considered to be a major challenge in the production industry while deciding the optimum machining parameters. The use of compliant damper is more economical in vibration isolation compared to the conventional dampers. To avail the best result, an appropriate optimisation technique may be used. However, it is the designing of damper that makes it critical such that no specific procedure or formulation has been identified. In this work, several approaches were made in the design stage itself and the model with the significant vibration absorption capacity was manufactured. The very reason where a compliant damper can be utilised in order to reduce this unnecessary vibration and improves the surface texture of the finished product. The experimental results were analysed for the importance of compliant damper and the influence of machining vibration in product quality. A significant reduction of about 18% of vibration and 47% of surface roughness was observed when using compliant damper made of mild steel material.
