This article reveals the chip formation and the reducing of cutting force mechanisms of nickel-based superalloy Inconel 718 under elliptical vibration cutting using finite element analysis software. The results are compared with traditional cutting methods. The elliptical motion trajectory of the tool in elliptical vibration cutting machining is analyzed, and a two-dimensional finite element elliptical vibration cutting model is established. The effects of dynamic impact on the elliptical vibration cutting of Inconel 718 were discussed in terms of the surface morphology, chip formation mechanism, and cutting force reduced mechanism. The simulation results show that (1) compared with traditional cutting, the surface morphology of the workpiece machined by elliptical vibration cutting is better, and the machined surface has obvious elliptic indentation; (2) in traditional cutting, sawtooth chips are formed through shear slip, while in elliptical vibration cutting, the faster relative cutting speed [Formula: see text], higher tool-tip temperature, and smaller material removal cross-sectional area cause a more prominent thermal softening effect in the chip formation process than that in traditional cutting, which leads to the plastic flow to be dominant in the material removal process, resulting in the strip chips; and (3) compared with traditional cutting, the normal cutting force and the tangential cutting force in elliptical vibration cutting are separately reduced about 51.4% and 60.8%.

In ABAQUS simulations, the Young's modulus and Poisson's ratio are set to vary with temperature by assigning fixed values. This approach can impact the reliability and accuracy of the simulation results. In this paper, the temperature-dependent functions of Young's modulus and Poisson's ratio are incorporated into ABAQUS using its secondary development capabilities. And simulate the ultrasonic vibration-assisted cutting (UVAC) process of titanium alloy TC4. Based on the analysis of the simulation results, the fitting function operates within the temperature range of the cutting simulation, which is of guiding significance for further development. It is discovered that as the amplitude increases, the chips gradually transition from C-shaped to irregular blocky ones, the cutting force gradually decreases, while the influence depth of the residual compressive stress first reduces and then increases, and when the amplitude is 16 microns, the influence depth of the residual compressive stress is the minimum, being 0.05 mm. In comparison to amplitude, the frequency has a relatively small impact on the chip shape and cutting force. As the frequency rises, the influence depth of the residual compressive stress shows a downward trend. With the increase of the feed rate, the chip width and crimp radius of the ultrasonic vibration-assisted cutting become wider, while the cutting force and residual stress gradually increase.
