Summary: This study investigates the coupling vibration of cutter and workpiece under the interaction of machine tool and process dynamic load during the milling of Al 7075-T651. A novel vibration prediction model is presented by investigating the dynamics between the milling excitation force and the response of the machine tool through the interaction analysis theory. The wavelet packet transform and the frequency response function are utilized to decouple the interaction between the dynamic force load and the vibration response.

Summary: This study investigated the effects of high-speed longitudinal-torsion ultrasonic vibration milling (LTUVM) on cutting forces and tool wear in comparison to conventional milling (CM) for Ti-6Al-4V. The results showed that ultrasonic vibration significantly improved tool wear, although the improvement effect on cutting forces decreased with increasing linear velocity. This study reveals the effectiveness of ultrasonic vibration in high-speed milling of titanium alloys.

Summary: High feed Milling is a new method that allows for high feed rates and increased machining efficiency by using face cutters with small entering angles. Experimental tests showed that while it can double cutting volume compared to traditional face cutters, it also leads to increased cutting forces, higher surface roughness, and vibration amplitudes.

Summary: GH4169 high-temperature alloy is widely used due to its excellent performance. Ultrasonic vibration-assisted milling can effectively reduce machining stress and improve chip-breaking effect and reduce milling force. However, the increase of milling speed weakens the chip-breaking characteristic, and the increase of radial cutting width increases the machining stress and milling force.

Summary: This paper investigates the effects of cutting speed on cutting force and surface integrity in conventional milling and longitudinal-torsional ultrasonic vibration-assisted milling. The study explores the advantages of torsional vibration cutting, including variable cutting thickness, variable-front-angle cutting, and chip pulling. The experimental results demonstrate that increasing cutting speed decreases radial cutting force and surface residual compressive stress, but increases surface roughness. Longitudinal-torsional ultrasonic vibration-assisted milling exhibits reduced cutting force and surface roughness compared to conventional milling.

Summary: This study investigates the effect of different parameters on milling force in longitudinal-torsional ultrasonic vibration milling (LTUM) of titanium alloy. By combining the kinematic theory of LTUM with the model of milling transient cutting thickness, a milling force equation is established and experiments are conducted. The experimental results show that milling force is positively correlated with cutting speed, cutting depth, and feed per tooth, while it is negatively correlated with ultrasonic amplitude and tool helix angle. The empirical model of milling force is established and its accuracy is verified by experimental data.

Summary: In this study, a dynamic milling model is established to analyze the harmonic amplitudes in the milling vibration signals, and it is proven that the ratios of harmonic amplitudes are sensitive to the remaining lamina thickness. Experimental results show that a classifier based on these harmonic amplitude ratios can estimate critical states of the vertebral lamina with a high success rate before the lamina cutoff, which is beneficial to improve the safety of the automatic bone milling operation of the spinal surgical robot.

Summary: High-speed micro-milling is a promising technology for producing micro and miniaturized products with high precision. However, tool vibration is a major challenge that affects product accuracy and tool life. This study investigates the effect of process parameters on reducing tool vibration in high-speed micro-milling and achieving stable machine operation. The results show that increasing cutting speed and depth of cut can decrease axial and radial thrust, leading to reduced vibration and force transmitted to the machine structure.
