“…Cutting force effects were most pronounced when vibrations were imposed on the tool in the same direction of cut [4]. Subsequently consistent reductions of regenerative chatter were observed with large improvements of the surface of finished work-pieces [13,14]. A significant impact on surface residual stresses was also observed in hard or difficult-to-machine alloys in a wide range of cutting conditions in oblique and orthogonal turning [15,16].…”

Abstract:The effects of frequency in ultrasonic vibration assisted milling (UVAM) with axial vibration of the cutter is investigated in this paper. A series of face-mill experiment in dry conditions were conducted on AISI 316L, an alloy of widespread use in industry. The finished surfaces roughness were studied along with basic considerations on tool wear for both conventional milling and an array of frequencies for UVAM in a wide range of cutting conditions. Surface residual stresses and cross-cut metallographic slides were used to investigate the hidden effects of UVAM.Experimental results showed competitive results for both surface roughness and residual stress in UVAM when compared with conventional milling especially in the low range of frequency with similar trend for tool wear.

“…The authors made use of a new cutting model which has been experimentally proven including ultrasonic vibration cutting process to predict the occurrence of regenerative chatter with 2DoF(degrees of freedom ) differential equations , where the intermittment cutting force is used to instead of continuous force in the practical cutting methods [1,2,3]. In order to study the mechanism of the occurrence of regenerative chatter, a numerical simulation is given under different cutting conditions according to the regenerative chatter model shown in Fig.…”

Ultrasonic vibration cutting (UVC) as an advanced technique has been widely used in order to increase productivity and stabilities in machining of difficult-to-cut materials. The authors presented a chatter monitoring and signal processing system for turning a slender workpiece. A suitable tool nose radius prevents the tool fracturing occurrence so that the instability of the machining process is markedly reduced by applying UVC. When employing the novel machining method of online monitoring vibration signals and adjusting cutting parameters in real time, there is no occurrence of chatter and the machining accuracy is close to predicted amplitude of vibration during the whole cutting process. At the same time, the tool life improves to some extent.

It has always been a critical issue to understand the material removal behavior of Vibration-Assisted Machining (VAM), especially on atomic level. To find out the effects of vibration frequency on material removal response, a three-dimensional molecular dynamics (MD) model has been established in this research to investigate the effects of scratched groove, crystal defects on the surface quality, comparing with the Von Mises shear strain and tangential force in simulations during nano-scratching process. Comparisons are made among the results of simulations from different vibration frequency with the same scratching feed, depth, amplitude and crystal orientation. Copper potential in this simulation is Embedded-Atom Method (EAM) potential. Interaction between copper and carbon atoms is Morse potential. Simulational results show that higher frequency can make groove smoother. Simulation with high frequency creates more dislocations to improve the machinability of copper specimen. The changing frequency does not have evident effects on Von Mises shear strain. Higher frequency can decrease the tangential force to reduce the consumption of cutting energy and tool wear. In conclusion, higher vibration frequency in VAM on mono-crystalline copper has positive effects on surface finish, machinablility and tool wear reduction.
