“…Obviously, AUMSM treatment can eliminate the surface grooves of the material. It has also been confirmed that ultrasonic nanocrystalline surface modification (UNSM) can improve the surface roughness, microhardness and compressive residual stress of bearings, and micro-pits can improve the fatigue life of bearings with relative motion oil film thickness [17][18][19][20][21]. The experimental results further show that the surface after AUMSM treatment is better than that after conventional cutting treatment [22].…”

To improve the fatigue life of the key component and the surface properties of the 30CrNi2MoVA steel material, advanced ultrasonic-milling composite superficial treatment was performed. The microstructure, surface roughness, friction and wear performance, surface hardness, fatigue life and environmental experiments of the steel with and without ultrasonic-milling have been carried out in detail. In comparison with those of the traditional dry cutting, the results show that the surface roughness of the samples after the advanced ultrasonic-milling surface modification fluctuates about 0.32 μm, and the surface hardness is increased by about 40% compared with the matrix hardness, and the fatigue life of the pump head connection shaft has been increased by more than 11 times. Advanced ultrasonic-milling surface modification technology can increase the local residual compressive stress and wear resistance on the material surface, which can make the material have better surface properties.

The main objective of this study is to optimize the CNC turning parameters that give the fine surface characteristics of aluminum-magnesium alloy (AlMg3). Optimization has been conducted using the response surface methodology. Experiments were carried out on a Samsung PLA25 CNC machine. Three PVD-coated insert cemented carbide cutting tools with nose radiuses were used. The influence on the machining responses of various machining parameters such as the cutting speed, the feed rate, and the depth of cut were examined. In mechanical machining and workpiece surface finish, tool geometry is crucial. the three variables cutting speed (B = 500, 700, and 900 rpm), feed rate (A = 0.3, 0.5, and 0.7 mm/rev), and depth of cut (C = 0.5, 1.0, and 1.5 mm). are known to have a major impact on surface quality, as well as the tool nose radius. An understanding of these ideal parameters would make it easier to save machining costs and enhance surface quality. The Taguchi method was used for the optimization of machining experiments based on a full factorial design, to determine three different parameters and levels, by using orthogonal arrays. The initial objective of this study is to find the optimum parameters based on the best combination (A, B, C) feed rate, cutting speed, and depth of cut of each nose radius used. Therefore, which of these parameters has the greatest influence on surface roughness.
