“…Zhu Y. W. [50] used micro-ultrasonic composite EDM technology to process texture on metal surfaces and found that the surface quality of micro pits is good, and the pit depth is greater than that of single ultrasonic and ultrasonic EDM. Liu [51] proposed a new self-tuning ultrasonic elliptical vibration cutting technology to realize efficient Ductile Machining of microstructure arrays on brittle materials. The results show that this technology can improve machining efficiency by 30% while maintaining excellent surface roughness and crack-free surfaces.…”

As the demand for the development and utilization of marine resources continues to strengthen, the service requirements for advanced marine equipment are rapidly increasing. Surface protection technology has become an important way of solving the tribological problems of extreme operating conditions and improving the safety performance of equipment by imparting certain special properties to the surface of the material through physical, chemical or mechanical processes to enhance the ability of the material to withstand external environmental factors. Combined with the extremely complex characteristics of the marine environment, this paper describes the commonly used surface protection technologies for metal materials in the marine environment. Research on surface texture was summarized under different surface reshaping technologies, as well as processes and coating materials under different surface modification technologies. Combined with the existing research progress and development trends of marine metallic materials, the surfaces of metal materials under the marine environment protection technology foreground are prospected and provide a reference for the improvement of equipment performance in extreme marine environments.

Difficult-to-machine materials (DMMs) are extensively applied in critical fields such as aviation, national defense, biomedicine, and other key fields due to their excellent material properties. However, traditional machining technology is difficult to precisely machine DMMs due to poor surface quality and low processing efficiency. In recent years, as a new generation of machining technology, field-assisted machining (FAM) technology based on innovative principles such as laser heating, tool vibration, magnetic magnetization, and plasma modification provides a new solution for improving the machinability of DMMs. It is advantageous to prevent the shortcomings of traditional machining methods, and has become a hot topic of research in the domain of ultra-precision machining of DMMs. Many new methods and principles have been presented and investigated one after another, yet few researches have been analysed and summarized from a comprehensive standpoint. To fill this gap and understand the development trend of FAM, this study provides an important overview of FAM, covering different assisted machining methods, application effects, mechanism analysis, and equipment design. The current deficiencies and future challenges of FAM are summarized to lay the foundation for the further development of multi-field hybrid assisted and intelligent field-assisted machining technologies.

“…From their analysis, it was observed that the roughness values had quite stable values if the tool T02 was used, and in the case in which the tool T01 was used, the stability of the roughness values was not adequate. The experiments showed that tools with improved construction (T02) allow the realization of a ductile-machining regime, and this, according to [35][36][37][38], can cause a reduction in the amplitude of vibrations and thus the roughness of surfaces. Additionally, the use of the spring washer allows the tool geometry to be modified adaptively according to the machining conditions, and this determines that a surface without cracks and a high machining efficiency can be obtained.…”

Machining processes through cutting are accompanied by dynamic phenomena that influence the quality of the processed surfaces. Thus, this research aimed to design, make, and use a tool with optimal functional geometry, which allowed a reduction of the dynamic phenomena that occur in the cutting process. In order to carry out the research, the process of cutting by front turning with transversal advance was taken into account. Additionally, semi-finished products with a diameter of Ø = 150 mm made of C45 steel were chosen for processing (1.0503). The manufacturing processes were performed with the help of two tools: a cutting tool, the classic construction version, and another that was the improved construction version. In the first stage of the research, an analysis was made of the vibrations that appear in the cutting process when using the two types of tools. Vibration analysis considered the following: use of the Fast Fourier Transform (FFT) method, application of the Short-Time Fourier-Transformation (STFT) method, and observation of the acceleration of vibrations recorded during processing. After the vibration analysis, the roughness of the surfaces was measured and the parameter Ra was taken into account, but a series of diagrams were also drawn regarding the curved profiles, filtered profiles, and Abbott–Firestone curve. The research showed that use of the tool that is the improved constructive variant allows accentuated reduction of vibrations correlated with an improvement of the quality of the processed surfaces.
