To investigate the effects of laser power, cutting depth, feed, and spindle speed on the surface roughness of the workpiece and the wear of the back face, a one-factor experiment was first conducted to determine the selection range of the experimental parameters. Subsequently, an orthogonal experiment including four factors and four levels was designed using the Taguchi method to analyze in depth the machining process of laser heating-assisted turning of alumina (Al 2 O 3 ) ceramic materials with cubic boron nitride tools. Through analysis of variance and main effect analysis of each factor, the magnitude of each turning parameter on surface roughness and tool wear was determined, and the best combination was obtained. Conventional turning was carried out under the optimal cutting parameters, and the scanning electron microscope surface morphology of the workpiece under the two cutting conditions of laser-assisted machining and conventional machining was analyzed and compared. The results show that compared with conventional turning, the surface removal of laser heating-assisted turning is more thorough, the surface particle distribution is more uniform, and the surface integrity is significantly improved. In the appropriate range of cutting parameters, increasing the laser power and reducing the cutting depth can significantly reduce the surface roughness of the Al 2 O 3 workpiece. Under the optimal parameter combination, the surface roughness value is Ra ¼ 0.793 μm, and the reduction range is 56.33%. By increasing the laser power, reducing the spindle speed and cutting depth, the degree of tool wear is significantly reduced. The tool wear value under the optimal parameter combination is VB ¼ 58.4 μm., which is reduced by 62.7%.

“…There is a multitude of process parameters to consider, leading to a lack of consensus regarding the optimal cutting speed for aluminum machining, as initially proposed by Taylor [13]. Critical parameters, such as cutting speed, depth of cut, and feed, have profound implications on surface roughness, which in turn significantly affects the fatigue life of a machined part [14][15][16][17][18][19]. Other contributing factors include the workpiece material, tooling, and cutting fluid utilization, which markedly influences the cutting forces and chip formation and disposal [20][21][22][23][24].…”

High-Speed Machining (HSM) of aluminum alloys represents a critical area in manufacturing industries, including automotive, aerospace and consumer electronics. This research presents an in-depth investigation into the effects of key process parameters on the HSM of Aluminum 7075, a high-strength alloy with superior mechanical properties. Utilizing the central composite design of Response Surface Methodology (RSM), the study scrutinizes the impact of process parameters, including cutting speed, feed, depth of cut and tool nose radius on surface roughness. The findings reveal feed and nose radius as primary factors influencing surface roughness while cutting speed and depth of cut play secondary roles. This comprehensive analysis contributes to the knowledge base for efficient machining practices and lays the groundwork for future optimization strategies. It also underscores the necessity for further research into understanding the intricate dynamics of machining parameters to enhance operational efficiency and product quality in the machining of Aluminum 7075 and similar alloys.

“…Dong et al [15] carried out laser heatingassisted micro-machining of SiC/SiC ceramic matrix composites, which reduced tool wear by 76% and increased tool life by 3.8-fold. Erdenechimeg et al [16] conducted experiments on the laser-assisted machining of carbon fiber-reinforced ceramic matrix composites and found that LAM cutting forces were reduced by 40.7% and roughness was reduced by 33.8% compared with CM Reza et al [17] conducted experiments on the laserassisted turning of a SiC-Al 2 O 3 -reinforced aluminum hybrid nanocomposite and found a 26% reduction in laser-assisted cutting forces and a 51% reduction in roughness, which were attributed to softening and plastic deformation of the aluminum matrix. Zhai et al [18] studied the characteristics and mechanism of the LAM of C/SiC composites with different fibre orientations (0°, 45°, 90°, 135°).…”

Ceramic matrix composites have high hardness, so their machining requires high grinding forces that cause severe wear of the grinding head. To investigate this problem, the present study investigated the cutting performance of conventional grinding (CG) and laser-assisted grinding (LAG) of SiCf/SiC ceramic matrix composites using electroplated diamond grinding heads. Firstly, a three-dimensional transient heat transfer model based on a Gaussian heat source was developed to observe the surface and internal temperature field distributions of SiCf/SiC ceramic matrix composites subjected to laser irradiation. Secondly, the effects of laser heating temperature on the workpiece surface on the grinding forces were analysed. It was found that the axial and feed grinding forces were more than 40% lower under LAG than CG due to the removal mechanism of the SiC matrix changing from brittle fracture to ductile fracture and the oxidation reactions occurred in the SiCf/SiC ceramic matrix composites. Thirdly, the material removal mechanism was analysed by observing the morphology of machined surfaces, which showed that ductile removal from the SiC matrix occurs during LAG. Finally, it is also founded that the mean height of exposed abrasive grains from machined surface was reduced by 1.02 μm, 12.52 μm in LAG and CG respectively. The forms of wear caused by abrasive grains were studied. Under CG, the abrasive grains mainly exhibit cleavage fractures; while under LAG, micro-abrasion is the main wear form.
