Special Issue Information

Dear colleagues,

Precision manufacturing is an important aspect of the modern manufacturing industry, enabling the production of components with high accuracy and complex geometries. Precision manufacturing technology involves many disciplines, such as mechanical engineering, materials science, and computer science, to promote the continuous innovation and development of manufacturing technology. Precision manufacturing technology has made much progress in improving product quality, production efficiency, and sustainable development in the areas of aerospace equipment, construction machinery, new energy vehicles, transport equipment, etc.

This Special Issue aims to present recent advances in precision manufacturing technology, which cover a broad scope, involving theoretical studies, manufacturing processes, and equipment development. In addition, we welcome research works about multidisciplinary manufacturing technologies, such as high-energy beam (laser, e-beam, and ion beam) processes and hybrid (additive combined with subtractive) manufacturing technology.

We are interested in articles that focus on topics including, but not limited to, the following:

  • Precision manufacturing technology for aerospace equipment.
  • Precision manufacturing technology for construction machinery.
  • Lightweight and intelligent manufacturing technology for vehicles and transport equipment.
  • Precision manufacturing processes for nonferrous metal, high-performance polymer, and metal matrix composites.
  • Extreme manufacturing, micro/nano-manufacturing, and additive manufacturing technology.

The scope of this Special Issue is based on "The First Academic Summit Forum on Precision Welding and Joining of Material Structures". For more information about the event, please visit the following link: https://weld.hit.edu.cn/2024/0711/c1648a348529/page.htm.

Nevertheless, we encourage all scholars, including those who have not yet attended the conference, to submit their papers to this Special Issue.

We look forward to your contributions and believe that this Special Issue will significantly contribute to the advancement of precision manufacturing technology. Should you have any inquiries, please do not hesitate to contact the Editorial Office.

The efficient and cost-effective preparation of masks has always been a challenging issue in mask-based electrochemical machining. In this paper, an electrochemical machining process of micro-textures is proposed using hard particle masks such as titanium and zirconia particles. Numerical simulations were conducted to analyze the formation mechanisms of micro-protrusion structures with insulating and conductive hard particle masks, followed by experimental verification of the process. The results indicate that when the hard particles are electrically insulating, metal material preferentially dissolves at the center of the particle gap, and the dissolution then expands over time in depth and towards the particle contact points. Conversely, using the conductive particles as the masks, such as titanium particles, dissolution initially occurs in a ring region centered at the contact point between the hard particle and the anode, with a radius approximately one-quarter of the chosen particle’s diameter (200 μm), and then continues to expand outward.

Difficult-to-cut titanium matrix composites (TiB+TiC)/Ti6Al4V have extensive application prospects in the fields of biomedical and aerospace metal microcomponents due to their excellent mechanical properties. Jet electrochemical micromilling (JEMM) technology is an ideal method for machining microstructures that leverages the principle of electrochemical anodic dissolution. However, the matrix Ti6Al4V is susceptible to passivation during electrochemical milling, and the inclusion of high-strength TiB whiskers and TiC particles as reinforcing phases further increases the machining difficulty of (TiB+TiC)/Ti6Al4V. In this study, a novel approach using NaCl+NaNO3 mixed electrolyte for the JEMM of (TiB+TiC)/Ti6Al4V was adopted. Electrochemical behaviors were measured in NaCl and NaCl+NaNO3 electrolytes. In the mixed electrolyte, a higher transpassive potential was required to break down the passive film, which led to better corrosion resistance of (TiB+TiC)/Ti6Al4V, and the exposed reinforcing phases on the dissolved surface were significantly reduced. The results of the JEMM machining indicate that, compared to NaCl electrolyte, using mixed electrolyte effectively mitigates stray corrosion at the edges of micro-grooves and markedly improves the uniformity of both groove depth and width dimensions. Additionally, the surface quality was noticeably improved, with a reduction in Ra from 2.84 μm to 1.03 μm and in Rq from 3.41 μm to 1.40 μm. Full article
