Special Issue Information

Dear Colleagues,

Mechanical machining or cutting, as a subtractive manufacturing operation, is one of the most widely used manufacturing processes. Although some emerging manufacturing processes, such as additive manufacturing, have advanced beyond rapid prototyping to the manufacture of structural and functional components, the dominant role of cutting is still irreplaceable owing to its flexibility, good surface quality, high material removal rate, and the capability to machine nearly all types of materials. Material properties generally have contrary relationships with their machinability, and materials with excellent thermal, physical, or mechanical properties are always difficult to process. With the rapid development of advanced engineering materials, new challenges have emerged in the field of cutting. The development of advanced tool/coating materials and technology will be aimed at improvements in production efficiency, product quality. and cost reduction. On the one hand, the intrinsic attributes of tool/coating materials, including their structures and properties, are essential factors that determine their cutting performance. On the other hand, the final surface produced by advanced cutting technology has unique structures and associated properties, which differ significantly from the original characteristics of the workpiece materials. It is thus urgent to gain deeper insights into the underlying relationships between the cutting process and machined surface integrity in order to guarantee the cutting efficiency and final surface quality of difficult-to-process materials.

Therefore, the objective of this Special Issue is the publication of original research and review articles in the field of cutting performance of difficult-to-process materials. Papers that employ advanced tool/coating materials and technology concepts to enhance machining processes are welcome. We also welcome scholars in related fields to contribute their latest research results to this Special Issue. Understanding the strengthening mechanisms of processed tool/coating materials and technology can provide a deeper comprehension of their machinability as well as machined surface evolution.

Suitable topics include, but are not limited to, the following.

  • Design and fabrication of new cutting tools with advanced tools and coating materials;
  • Fundamentals in the relationships of “tool/coating material–property–cutting performance”;
  • Development of new manufacturing technologies, such as cutting/milling/grinding/polishing/hybrid processing;
  • Assisted machining technologies such as ultrasonic-assisted machining (UAM), vibration-assisted machining (VAM), laser-assisted machining (LAM), etc.;
  • Enhancing mechanisms of the machining process with advanced tool/coating material and technology;
  • Tool wear mechanisms and their monitoring;
  • Machined surface integrity and the evolution of material structure and properties during the cutting process;
  • Performance evaluation of processed functional components after the cutting process;
  • Machining mechanics, applications, and challenges

Graphene foam composite is a promising candidate for advanced thermal management applications due to its excellent mechanical strength, high thermal conductivity, ultra-high porosity and huge specific surface area. In this study, a three-dimensional physical model was developed in accordance with the dodecahedral structure of graphene foam composite. A comprehensive numerical simulation was carried out to investigate the fluid flow and convective heat transfer in open-cell graphene foam composite by using ANSYS Fluent 2021 R1 commercial software. Research results show that, as porosity increases, the pressure gradient for graphene foam composite with circular and triangular cross-section struts is reduced by 65% and by 77%, respectively. At a given porosity of 0.904, when the inlet velocity increases from 1 m/s to 5 m/s, the pressure gradient is increased by 11.3 times and 13.8 times, and the convective heat transfer coefficient is increased by 54.5% and 43% for graphene foam composite with circular and triangular cross-section struts, respectively. Due to the irregularity of the skeleton distribution, the pressure drop in Y direction is the highest among the three directions, which is 8.7% and 17.4% higher than that in the Z and X directions at the inlet velocity of 5 m/s, respectively. The convective heat transfer coefficient in the Y direction is significantly lower than that along the X and Z directions. Furthermore, triangular cross-section struts induce a greater pressure drop but offer less effective heat transfer compared to circular struts. The research findings may provide critical insights into the design and optimization of graphene foam composites, and promote their potential for efficient thermal management and gas/liquid purification in engineering applications.

Inconel 718 has excellent thermal and chemical properties and is widely used in the manufacture of aerospace parts; however, there are some problems in the machining of Inconel 718, such as a large milling force, serious tool wear, and poor surface quality. In this research, a type of longitudinal–torsional ultrasonic milling (LTUM) tool is designed based on theoretical computations and FEM simulation analysis. To verify the design rationality of the developed LTUM tool, milling experiments are performed. It is verified that the LTUM tool can realize an elliptical vibration path at the tool tip. The resonance frequency of the tool is 21.32 kHz, the longitudinal amplitude is 6.8 µm, and the torsional amplitude is 1.4 µm. In the milling of Inconel 718, the experimental data of LTUM are compared with those of conventional milling (CM). The comparative experiments show that the LTUM tool can effectively lessen the milling force and tool wear in the milling of Inconel 718, improve the surface quality, inhibit the generation of burrs, and improve the chip breaking ability. The application potential of the LTUM tool in high-performance milling of Inconel 718 parts is proven. Full article
