A Comparative Assessment to Evaluate Force and Stress of Nimonic 80A for Different Grinding Schemes
摘要
Due to their undesirable properties at higher temperatures, machining nickel-based superalloys presents substantial challenges. Additionally, environmental concerns arise due to the generation of temperature during the process. In order to address these issues related to traditional grinding, this work focuses on enhancing sustainability and performance by modifying the grinding process. This is attained with amalgamation of high frequency and low amplitude into the Conventional Grinding (CG). The study examines various grinding approaches, analyzing cutting forces, temperature, and simulated value of stress. In the results section, the addition of high frequency and low amplitude of ultrasonic vibration showed positive upshots in grinding forces and temperature as compared to CG. Notably, UAG yields significant reductions in both normal and tangential cutting forces as well as a reduction in grinding temperature compared to CG. Based on the material removal process, forces were calculated experimentally for the UAG and CG. Afterward, these forces have been applied to the grinding zone to estimate the resulting stresses. This study provides the path to predict stress values after incorporating ultrasonic vibration onto the workpiece materials.
