Summary: This study investigated the laser-assisted machining (LAM) of aluminum nanocomposite reinforced with SiC-Al2O3 nanoparticles using the turning process. The factors of laser power, depth of cut, and cutting speed were optimized using the Taguchi method to achieve the smallest surface roughness and cutting force. Results showed that the depth of cut had the greatest influence on cutting force in LAM and conventional machining (CM) processes, while cutting speed and feed rate had the major effect on surface roughness in LAM and CM processes, respectively. LAM exhibited a 26% reduction in cutting force and a 51% decrease in surface roughness compared to CM process under optimal conditions.

Summary: This study focuses on the development and performance examination of Functionally Graded Concrete (FGC) in concrete pipes. FGC is made by varying the material composition, resulting in changes in the overall behavior of structures. The study uses micro steel fiber and basalt fiber to create functional gradation. The mechanical performance of the fiber reinforced concrete is studied with different volumetric fractions, and the optimal FGC is used to cast functionally graded concrete pipes (FGCP) and analyze their performance.

Summary: Advanced machining is essential for the fabrication of high-precision miniature industrial components. This study examines the machinability of Mg-rare earth (RE) alloy-based nanocomposites using wire electrical discharge turning (WEDT). The results show that the surface roughness (R-a) increases and the volume of material removed (MRR) decreases with the increase of reinforcement percentage and discharge ON time.

Summary: Glass-fibre-reinforced plastic (GFRP) is popular for various applications due to its high strength-to-weight ratio, stiffness, fatigue resistance, low coefficient of thermal expansion, and tailorable properties. Milling GFRP composites is challenging because of their heterogeneous nature and two-phase structure which result in high cutting forces and delamination. A statistical experiment using the Taguchi design of experiments was conducted to investigate the effect of machining settings on GFRP composite performance metrics.

Summary: The study found that cutting parallel to the fibre direction resulted in a higher material removal rate compared to cutting perpendicular to the fibers, but also led to larger kerf widths and poorer surface roughness. Additionally, the cutting direction also affected the severity of defects on the workpiece surface.

Summary: This paper focuses on the laser cleaning of 34CrMo(4) steel pipes before the electrical upsetting process. The aim of the cleaning is to decrease the pipe roughness and the electrical resistance with copper inserts for better wear resistance and electrical contact. Experimental tests were conducted using a 30-W Q-switched Yb:YAG fibre laser with different cleaning parameters to identify a workability range. The results showed that laser cleaning leads to lower pipe roughness and reduced wear of copper inserts compared to shot blasting. A pre-industrialisation analysis was also performed using higher laser power sources to reduce cleaning time and optimize the industrial setup.

Summary: In this study, radial high-speed ultrasonic vibration cutting (R-HUVC) process was adopted to improve the machining performance of finishing hardened steel. Experimental results showed that R-HUVC can achieve lower cutting force, longer tool life, and better surface roughness compared to conventional cutting (CC). It was demonstrated that R-HUVC can be applied to high-speed machining for the finish turning of hardened steel due to its improved machining performance.

Summary: This experimental study used infrared thermography as a control parameter of surface roughness in dry finish turning. The analysis of variance showed that cutting speed and feed rate had a significant effect on surface roughness and cutting temperature. Higher cutting speeds and intermediate feed values yielded the best surface roughness.

Summary: Magnesium alloys are widely used in engineering sectors for their lightweight, stiffness, and damping properties. However, machining these alloys poses challenges due to their mechanical properties and inflammability. In this study, a newly developed Aluminum-Manganese (AM) series Mg alloy was subjected to turning operation, with control factors including feed, speed, and depth of cut. Statistical analysis revealed that depth of cut has the greatest impact on cutting force, while feed has the greatest influence on surface roughness.

Summary: Compared to conventional fibre-reinforced composite pipes, fibre-reinforced hybrid composite pipes are more complex due to the use of hybrid fibres, hybrid matrices, and multiple winding angles. This study improved upon the mechanical model of conventional pipes and established a model for fibre-reinforced hybrid composite pipes with any number of reinforced layers. Results showed that the matrices hybrid methods have a significant influence on the axial tensile properties of these pipes, and improving the material properties of the inner and outer liners can greatly enhance their performance.

Summary: Natural fibre composites are a promising replacement for synthetic fibres due to their improved properties, biodegradability, and low cost. However, challenges in manufacturing and machining hinder large-scale production. Efforts have been made to study machining characteristics and failure mechanisms of fibre composites in both conventional and unconventional methods.
