INTRODUCTION The increasing demand for vehicles with reduced fuel consumption and emission is the reason why the material aluminum is frequently used for crankcases in the automotive industry. A method to increase the wear resistance of the cylinder bore surface is to use hyper-eutectic cylinder liners, which are cast-in or are assembled by force fitting. Another possibility to improve the trib...

This study investigated the optimization of computer numerical control (CNC) boring operation parameters for aluminum alloy 6061T6 using the grey relational analysis (GRA) method. Nine experimental runs based on an orthogonal array of Taguchi method were performed. The surface properties of roughness average and roughness maximum as well as the roundness were selected as the quality targets. An...
