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: 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: In order to contribute to sustainable machining, an investigation was conducted on the turning of martensitic stainless steel X20Cr13 using alternative cooling and lubrication techniques. The minimum quantity lubrication technique combined with vortex tube cooling was applied to determine the optimal cooling method. The aim was to identify the parameters that significantly affect surface roughness and tool life under the optimal cooling condition. Results indicated that only the feed rate significantly influenced surface roughness, while all three parameters (cutting speed, feed rate, and depth of cut) had a significant influence on tool life. Experimental results were compared with a mathematical model, and a new nozzle design allowed for simultaneous lubrication and cooling. The minimum quantity lubrication technique with vortex tube cooling is recommended for turning martensitic stainless steel X20Cr13.

Summary: Alpha + beta titanium alloys, specifically Ti-6Al-7Nb, are increasingly important in the biomedical industry, with CNC machining playing a crucial role in producing high-quality components. Metal chip analysis is an established method for machining optimization, especially for difficult-to-cut materials that form saw-tooth/segmented chips. A novel automated method was developed for quantifying the geometric aspects of saw-tooth chips in Ti-6Al-7Nb alloy using optical microscopy and digital image processing. This methodology offers the advantage of fully automated analysis, which is typically done manually, and the measurements' robustness was ensured through the selection of shape descriptors tested at various cutting speeds.

Summary: Currently, Ti-6Al-4V alloy is widely used in biomedical devices but its toxicity due to vanadium ions has led to efforts to find less toxic alternatives, such as Ti-6Al-7Nb alloy. The surface properties and tribological performance of the Ti-6Al-7Nb alloy are of great importance for its biomedical applications. This study investigates the fractal behavior of worn surfaces of both Ti-6Al-4V and Ti-6Al-7Nb samples through tribological tests and surface inspection methodologies.

Summary: Incremental sheet forming (ISF) is widely used for small batch production in sheet metal fabrication, and it does not require or only requires partial dies. This study compares two variations of ISF, namely cold ISF (CISF) and warm ISF (WISF). FEA modeling and tests show that WISF reduces forming forces, but CISF produces more substantial parts while WISF achieves greater forming depth. CISF has a more uniform thickness distribution, but WISF has better surface quality. WISF also has reduced forming force, increased formability, and better strain distribution compared to CISF.

Summary: This article investigates the hole generation mechanism in Graphene nanoplatelets/Carbon fiber (GnP/C) reinforced polymeric composites. By adding highly conductive GnP powder, the limitation of low conductivity in conventional Carbon fiber reinforced polymer (CFRP) composites is overcome. The effect of GnP concentration and voltage alteration on hole dilation during micro electrical discharge machining (mu EDM) is analyzed, and it is found that GnP concentration is the most significant factor. Additionally, the thermal nature variation generates micro-cracks in the laminates, which is observed through high-resolution microscopy.

Summary: The current research focuses on utilizing diverse biodegradable oils as dielectric fluids in electro-discharge machining (EDM) processes to address the challenges of environmentally friendly dielectric fluid. EDM is a cutting-edge, non-traditional technology for machining extremely hard materials. In this research, Ti-6Al-4 V material was machined using conventional EDM oil and four distinct bio-dielectric fluids. The primary goal is to identify an appropriate bio-dielectric fluid that is environmentally acceptable, cost-effective, and provides better machining performance compared to other dielectric fluids on the market. Mixed vegetable oil is found to be the best bio-dielectric fluid when considering MRR, TWR, and SR, while sunflower oil is the best dielectric when considering only MRR. It was discovered that the surface obtained with sunflower oil has the best crack size and number compared to other dielectric fluids.
