“…Some researchers have used lasers to induce material surface modifications to assist milling. Xia et al [150][151][152][153][154][155][156][157][158][159][160][161] proposed a novel hybrid machining process of laser-induced oxidation-assisted milling (LOAM) to enhance the machinability of difficult-tocut materials. By utilizing a pulsed laser, an oxidation reaction was induced between the irradiated workpiece material and oxygen, as shown in figure 15(a).…”

Difficult-to-cut materials such as titanium alloys, high-temperature alloys, metal/ceramic/polymer-matrix composites, hard and brittle materials, as well as geometrically complex components such as thin-walled structures, micro channels and complex surfaces, are widely used in aerospace community. Mechanical machining is the main material removal process and responsible for the vast majority of material removal for aerospace components. Nevertheless, it encounters many problems in terms of severe and rapid tool wear, low machining efficiency, and deteriorated surface integrity. Nontraditional energy-assisted mechanical machining is a hybrid process in which nontraditional energies, e.g., vibration, laser, electric, etc., are applied to improve the machinability of local material and decrease burden of mechanical machining. It provides a feasible and promising way for improving machinability and surface quality, reducing process forces, and prolonging tool life, etc. However, systematic reviews of this technology are lacking with respect to the current research status and development direction. This paper reviews recent progress in nontraditional energy-assisted mechanical machining of difficult-to-cut materials and components in aerospace community. It focuses on the processing principles, material responses under nontraditional energy, resultant forces and temperatures, material removal mechanisms and applications of these processes including vibration-, laser-, electric-, magnetic-, chemical-, cryogenic cooling-, and hybrid nontraditional energies-assisted mechanical machining. Eventually, a comprehensive summary of the principles, advantages and limitations for each hybrid process is provided, and future perspectives on forward design, device development and sustainability of nontraditional energy-assisted mechanical machining processes are discussed.

Laser Beam Machining (LBM) has several applications in the aerospace, medical, and automobile domains. Optimization techniques are essential for LBM to increase resource-efficiency and sustainability of the system. The present paper aims to provide a systematic review of the research in the domain of optimization techniques for LBM. A total of 228 research papers published during the last 20 years, from 2003 to 2023, are reviewed. The literature review is classified into three major sections- (i) optimization techniques, (ii) applications of optimization techniques, and (iii) challenges and future directions. The novelty of the present systematic review paper is to provide a direction for future research in the domain of optimization techniques of LBM. As a result of the suggested research, an efficient and sustainable LBM with the required performance will be developed in the shortest possible time.

“…This film is formed within a short period of time, and as the oxidation reaction proceeds, its porosity increases, which eventually leads to the generation of cracks and voids. Based on such oxidation behavior, new methods of titanium alloy micromachining have been developed, including electrochemical micromilling (ECMM) [35] and laser-induced oxidation-assisted micromilling (LOMM) [36]. Niu et al used the former method to optimize the processing parameters of high-temperature alloy materials.…”

This paper develops a novel processing method of plasma electrolytic oxidation-assisted micromilling (PEOAM). Electrolyte solutions with KH2PO4, NaAlO2, or Na2SiO3 as the main component are designed, and three types of oxide films are grown on the surface of a Ti6Al4V alloy in situ by means of plasma electrolytic oxidation. The morphology and composition of the oxide films are characterized by scanning electron microscope and energy dispersive spectrum. Additionally, the cutting force and surface roughness of PEOAM are measured by dynamometer and white light interferometer, respectively. A comparison between PEOAM and conventional micromilling in terms of cutting force, tool wear, chips, and surface roughness is conducted, with results showing that oxide films with about 20 μm thickness are loose and porous, their hardness decreasing to a minimum of 1.12 GPa, which corresponds to 23.3% of the original hardness value. At the axial cutting depth of 18 μm, compared to the Fx, Fy , and Fz values of the Ti6Al4V alloy substrate, the average milling forces of the NaAlO2 oxide film are the most significantly reduced (35.1%, 15.7%, and 94.8% of the original values, respectively). At the axial cutting depth of 25 μm, the surface roughness (R a) value of PEOAM is reduced by 0.08–0.12 μm. Consequently, under the same cutting parameters, PEOAM can effectively reduce the cutting force, prolong the service life of the tool, and improve surface quality.
