A Study of Tool Motion in 2 Dimensional Ultrasonic Assisted Micro-Milling
This paper present a study of the 2 dimensional ultrasonic vibration assisted micro-milling (UVAM) focused on the tool motion shape and tool trajectory. The cutting characteristics in 2 dimensional are in view by considering the trajectory of the amplitude of vibration towards tool locus into the workpiece during the tool rotation are explore in depth. The vibration platform travel in Xf direction known as a feedrate movement, thus the X and Y axis vibration generate simultaneously through the workpiece surfaces. Amplitude value acting on X and Y axis proposed a major effect as it will effectively change the shape of tool trajectory between oval and eclipse. This investigation found the major advantages of UVAM is come from the alternating cycle’s gap phenomena between tool and workpiece. The reduction of prediction of cutting force and the thinning chip thickness formations has been observe during the investigation. The theoretical finding will be discussing the potential to extended tool life, surface roughness and material removal rate in the conclusion for future research plan.
