Description
Summary:The SiC particle-reinforced aluminum matrix composites (MMCs) possess a low machinability due to their evident hardness difference. The underlying cutting mechanism is investigated in ultrasonic vibration cutting (UVC) of SiC/Al by finite element analysis, underlining its dependence on employed vibration parameters. Simulated results indicate that the high frequency in the x - and y -direction ultrasonic vibration leads to the reducing time-averaged cutting force and cutting temperature at the tool tip. Nevertheless, the large amplitude in the unidirectional ultrasonic vibration results in a reduce of the time-averaged cutting force and an increase of the time-averaged cutting temperature. It is also found that the maximal cutting temperature located at the tool tip shows a similar trend to the time-averaged cutting temperature with variation of ultrasonic vibration parameters. Corresponding experiments of UVC and conventional machining using the identical machining and material parameters to the FE simulations are also conducted to validate the present finite element model.
