Multi-Objectives Optimization of Abrasive Water Jet Machining (AJWM) on Mild Steel
No full textAbrasive waterjet machining (AWJM) is an advanced machining technology that is commonly used to machine hard materials that are difficult to machine using traditional methods. AWJM with a narrow stream of high-velocity water and abrasive particles offers a low-cost and environmentally friendly machining approach with a high rate of material removal. Some issues that were usually highlighted while cutting the metal are poor appearance cutting due to visible stream lagging particularly when working at high-speed cutting. This can lead to decreased accuracy and precision in the cutting process. Past literature is mostly focused on improving the machining performances through intensive experimental works, thereby not many studies are concerned on process optimization through design of experiment approach. In this regard, this study aims to statically analyze how the controlled machining factors; transverse speed and cutting geometry influence surface roughness, and dimensional accuracy of a mild steel plate under the AWJC process. A two level Full Factorial method was applied to design the experiment that entailed 6 sets of parameters. Through the Analysis of Variance (ANOVA) on the experimental results, it was found that the dimensional accuracy is significantly influenced by the changes of cutting geometry. The factor also interacts with transverse speed to affect surface roughness. For optimization, the ANOVA suggest a transverse speed of 40% as the optimum value to produce a surface at 2.85 µm of roughness and a dimension accuracy of 0.177% for the circular geometry-controlled factor.

Flowability Properties of PLA/PA12 Composite with Varying Wollastonite Concentrations for 3D Printing Applications
No full textThis study evaluates the rheological properties and flow behaviour of PLA/PA12 composites with varying concentrations of wollastonite (WA) ceramic particles (5, 10, and 15 wt.%) to enhance their biological performance and printability in 3D printing applications. Achieving the right balance of viscosity and flow is crucial for producing high-quality filaments and reliable 3D printed structures. Comprehensive rheological analysis and material characterization were conducted, including particle size distribution, SEM, and EDX. The flow behaviour index (n) was calculated, and physical observations of extruded materials were assessed for surface quality and dimensional consistency. The 10 wt.% WA composite consistently demonstrated superior rheological properties, exhibiting optimal pseudoplastic behavior with an n value range of 0.073–0.439 and a viscosity of 5919 Pa·s at 140 °C, which was the lowest among the composites tested, ensuring smooth extrusion and structural integrity. SEM analysis showed a uniform microstructure with well-dispersed WA particles in the 10 wt.% WA composite, while the 5 wt.% WA and 15 wt.% WA composites displayed suboptimal particle distribution. Physical observations confirmed that the 10 wt.% WA composite produced a smooth, consistent extrudate, essential for high-quality filament fabrication and reliable 3D printing. These findings highlight the 10 wt.% WA composite as the most promising candidate for efficient and effective 3D printing
Radiation Dose of Abdominal and Lung Computed Tomography Based on Body Mass Index as an Indicator
No full textBackground: Radiation dose generated from computed tomography (CT) has drawn more attention to diagnostic radiology. It is a known fact that the risk of radiation-induced cancer is increasing, thereby necessitating the optimisation of dose in CT protocols. This study focused on determining the radiation dose of CT scans for the abdomen and lung using a 64-slice CT scanner to evaluate their correlation with body mass index (BMI). The objective of the study was to critically evaluate the relationship between BMI and radiation dose metrics in both CT lung and CT abdomen examinations.
Methods: Data from 106 patients who underwent CT lung and CT abdomen examinations at an advanced diagnostic center were retrospectively analysed. The volume CT dose index (CTDIvol), dose-length product (DLP), the scan range, and cranium diameter [antero-posterior (AP) and lateral (LAT)] of the patients were documented for further analysis. Effective dose (E) and size-specific dose estimate (SSDE) were also computed.
Results: The mean BMI for CT lung was recorded as 24.85 (5.65). However, the correlation between BMI and the dose metrics (SSDE, E, DLP, and CTDIvol) was not significant, with correlation coefficients of 0.1278, 0.047, 0.047, and 0.1147, respectively. In contrast, the BMI for CT abdomen scans showed a moderate correlation with E (0.5898), SSDE (0.6288), DLP (0.5898), and CTDIvol (0.612). The results demonstrate that BMI can be used as a radiation dose metric in the case of CT abdomen scans, but has no influence on CT lung scans.
Conclusion: These results further suggest that BMI could provide radiation dose analysis, which in turn leads to optimisation of CT scan parameters

Rheological, mechanical and physical properties of poly-lactic acid (PLA)/ hydroxyapatites (HA) composites prepared by an injection moulding process / Afeeqa Puteri Marzuki … [et al.]
No full textPoly-lactic acid (PLA) is an attractive biopolymer where it is biocompatible with respect to biomedical applications. Hydroxyapatite (HA) ceramics have been broadly practiced as bone substitutes because of their chemical composition close to the mineral phase of bone. Indirectly, the combination of PLA and HA would be a suitable biomaterial candidate for implant and bone repair applications. In this study, the feedstock composition of PLA/HA has been investigated to obtain good rheological properties before undergoing an injection moulding process. The process begins with mixing the specific powder loadings of 60 wt.% PLA/ 40 wt.% HA at 30 rpm of rotating speed and 180 oC of mixing temperature. Then, the feedstock is evaluated using a capillary rheometer at three different temperatures, 140 oC, 150 oC, and 160 oC. Feedstock exhibiting pseudoplastic flow (n<1) is chosen for the injection moulding process. The result shows injected moulded part successfully produced at barrel and nozzle temperature of 160 oC, mould temperature of 37 oC and injection pressure of 0.7 MPa. The injected parts were characterized for physical and mechanical properties. The PLA/HA specimen density is 1.564 ± 0.02 g/cm3. The Young’s Modulus of the tensile is 1.82 ± 0.5 GPa within the range of human bone, 1.15 to 5.44 GPa
