Summary: In this study, the cutting characteristics of Zr57Cu20Al10Ni8Ti5 (at.%) bulk metallic glass (Zr57 BMG) were compared with industrial pure zirconium (Zr702) during high-speed machining (100-350 m/min). It was found that despite the higher strength of Zr57 BMG, there was no significant difference in the main cutting forces between the two materials, which was attributed to the thermal softening of Zr57 BMG during machining. Furthermore, the surface characteristics and chip morphology changed as the cutting speed increased, with the worst surface quality obtained at a speed of 250 m/min.

Summary: The study examined the effects of cutting parameters on the surface roughness and chip morphology of high-speed milling wood-plastic composites. It was found that the surface roughness increases with the axial depth, feed rate, or radial depth, but decreases with spindle speed. Additionally, the axial depth, feed rate, and spindle speed significantly influenced chip morphology.

Summary: This paper focuses on the effect of process parameters on the milling performance of nickel-based superalloys using AWJ. The prediction models for milling depth and surface roughness were established. Waterjet pressure is the most influential factor, while abrasive flow rate has the least impact. The interaction between nozzle tilt angle, waterjet pressure, and milling depth was also investigated. The validation experiment confirms the validity of the established models.

Summary: In this study, a new TiAlSiN-coated tool was developed using high-power pulsed magnetron sputtering (HiPIMS) to improve the Si and Al contents in a coating composition. The performance of the TiAlSiN-coated tool was compared with four commonly used coated tools in milling 304 stainless steel under minimum quantity lubrication. The TiAlSiN-coated tool showed stable machining performance with the smallest compound milling force and tool wear. It exhibited good processing stability, wear resistance, and low surface friction, making it superior to the other four commercial-coated tools, especially under certain working conditions.

Summary: This study investigates the optimization parameters for micro-milling of Mg13Sn alloy and examines the effects of different cutting parameters on cutting forces and surface roughness. The results indicate that increasing the feed rate and depth of cut significantly increases the cutting forces, while increasing the cutting speed noticeably reduces the cutting forces. Additionally, the study finds that surface roughness increases with increasing feed rate but decreases with increasing cutting speed. The findings offer important insights for micro-milling of Mg13Sn alloys.

Summary: Recent years have seen the rapid growth of microscale manufacturing in various industries, such as biomedical, electronics, and aerospace. In order to produce intricate features with high surface quality, it is necessary to improve the capabilities of micro-cutting processes, including micro-milling. The proposed work focuses on enhancing the surface finish and compressive residual stress of milled slots by manipulating the pre-compressive stress condition. Ultrasonic-assisted abrasive peening is used to tailor residual stress and refine grain on the surface, resulting in reduced surface roughness and improved compressive residual stress.
