Mathematical Modeling of Surface Roughness and Vibrations for CNC Turning of Aluminum Alloy (HE30)

The optimization and automation plays very important role in manufacturing industry. For this tool condition monitoring system becomes necessary part in manufacturing industry. In this study, experimental investigations were carried out to investigate the effect of cutting parameter on vibration signals during turning. For this the vibration signals in three directions namely Feed (Vx), Radial (Vy), and Tangential (Vz) were measured with different cutting condition. From experimentation it is observed that vibration in feed direction affected by cutting parameter. Feed component of vibration signals has higher values followed by radial component and finally tangential component. From experimentation it is also observed that, surface roughness increases with increasing feed rate and depth of cut. Also the mathematical modeling of vibration signals and surface roughness in terms of cutting parameter is developed for better understanding.
