Optimizing Ergonomic Efficiency through a Comprehensive Anthropometric Approach in Laboratory Furniture Design for Malaysian University Students Tan Min Fang, Chong Yee Ying, Aung Qinkang, Siti Nur Izzati Ahmad Rosli, Aiman Ikram Abu Bakar, et al. Semarak Engineering Journal, 2025 Ergonomic design is crucial for ensuring safety, comfort, and productivity in learning environments that involve intensive manual tasks. In higher education, laboratories play a crucial role in fostering applied technical skills. However, poorly designed laboratory furniture can lead to discomfort, fatigue, and long-term health issues, especially when workstation dimensions are mismatched with the body measurements of the users. This study was undertaken at the School of Mechanical Engineering, Universiti Sains Malaysia, to evaluate and improve the ergonomic design of furniture in the welding laboratory. A survey involving 40 students (20 male and 20 female) aged between 20 and 25 years was conducted to collect 12 key anthropometric parameters, including stature, shoulder breadth, popliteal height, buttock–popliteal length, sitting elbow height, and hip breadth. Data were analyzed using SPC XL software to compute the mean, standard deviation, and percentile distributions (5th, 50th, and 95th percentiles). Comparative analysis between student anthropometry and current furniture dimensions revealed substantial mismatches, particularly in seat height, seat depth, and table height. Based on these findings, the study proposed ergonomic modifications, including an adjustable laboratory chair with lumbar support and rotation capability, as well as a detachable table riser to accommodate users across various percentile ranges. Post-intervention feedback and ergonomic evaluation demonstrated measurable improvements in posture, reach, and overall comfort, with mismatch rates reduced by up to 80–85%. This study extends ergonomic theory by translating localized anthropometric data into percentile-based design ranges that align with international ergonomic principles, specifically the design-for-extremes and adjustability frameworks defined by ISO 7250 and ISO 6385. The results provide a replicable model for ergonomic standardization in Malaysian educational laboratories, emphasizing evidence-based design for inclusivity and safety.
Enhancing the Wear Resistance of Ti6Al4V by Laser Surface Texturing M.H Zul, M. Ishak, Ramdziah Md. Nasir, M.H Aiman, M.M Quazi Materials Science Forum, 2025 This study examines the wear behavior of Ti6Al4V following nanosecond pulse laser surface texturing (LST) using 15 W power, 60 kHz frequency, and 180 mm/s speed. Tested under dry sliding conditions with a 20 N load, 0.3 m/s speed, and 900 s duration, LST produced melt bulges that enhanced surface wear resistance. This study demonstrates that nanosecond pulse laser surface texturing on Ti6Al4V significantly enhances wear resistance, reducing wear rate by 3% and coefficient of friction by 5%.

Tribological performance of additive-manufactured aluminum alloy—effect of post-weld cold deformation SSM Noor Ariffin, AB Abdullah, RM Nasir, R Rajendran, SYM Yusuf, NA Jaafar Proceedings of the Institution of Mechanical Engineers Part J Journal of Engineering Tribology, 2024 Aluminum alloys are widely used in various automotive parts because of their high strength-to-weight ratio. However, their tribology properties, such as wear rate, are relatively high, resulting in a shorter life span than expected. Reconstructing the worn area using welding-based additive manufacturing (AM), such as wire arc AM, offers many advantages. However, heat may decrease the strength and hardness of the deposited material. This study intends to investigate the tribology properties of additive-manufactured aluminum alloy and their effects on mechanical deformation via cold forging. In this study, a reciprocating ball-on-flat test based on ASTM G133 is utilized. The additive-manufactured aluminum alloy ER5356 is studied based on three parameters, i.e. forged/unforged condition, speed, and load. In conclusion, cold forging improves the properties of the deposited material. Optimization using the Taguchi method and analysis of variance verifies that cold forging condition is the most significant parameter for the coefficient of friction and wear rate pattern. The SEM observation seems to agree with the wear pattern.
Superhydrophobic Surface of Ti6Al4V using Direct Nanosecond Laser Texturing Mohd Harizan Zul, Mahadzir Ishak, Aiman Mohd Halil, Ramdziah Md Nasir, Moinuddin Mohammed Quazi Journal of Advanced Research in Micro and Nano Engineering, 2024 This study aims to investigate the impact of laser parameters, including laser power, laser frequency, laser scan speed, and hatches line distance, on Ti6Al4V to create superhydrophobic surfaces. Surface profile and roughness play vital roles in achieving superhydrophobicity, and existing laser surface modification methods are time-consuming and lack subsequent steps for optimizing desired characteristics. A factorial design was implemented, varying laser power (12 and 18 W), laser frequency (40 and 60 kHz), laser scan speed (180 and 220 mm/s), and hatch line distance (0.25 and 0.45 mm). Surface morphology and topological properties were analyzed for surface characterization. The results demonstrate a significant increase in surface roughness profiles such as Sa and Sq by 6 and 5 times, respectively, compared to the untextured surface. These modifications also led to enhancements in surface topological properties. Regression analysis revealed the importance of controlling the surface profile for achieving superhydrophobicity. Statistical analysis indicated that laser power, laser frequency, and laser speed were the most significant parameters contributing to superhydrophobicity. The optimum laser parameters for superhydrophobic surfaces were determined as 18 W laser power, 40 kHz laser frequency, and 220 mm/s laser scan speed. In conclusion, this study emphasizes the critical role of surface topological properties in creating superhydrophobic surfaces on Ti6Al4V. Laser texturing techniques successfully improved surface roughness and profile, facilitating the development of superhydrophobic surfaces. These findings offer valuable insights for advancing surface engineering, with potential applications in the aerospace, automotive, and biomedical industries.
Effect of multi-geometrical laser pattern of Ti6Al4V on frictional wear behaviour Jurnal Tribologi, 2024
Effect of Laser-Textured Surface of Ti6Al4V on Frictional Wear Behavior M.H. Zul, Mahadzir Ishak@Muhammad, R.M. Nasir, M.H. Aiman, M.M. Quazi International Journal of Automotive and Mechanical Engineering, 2023 The need for titanium and its alloys has led to a significant increase in commercial manufacturing, although this material’s poor tribological qualities have been a drawback. The present study was to determine the effect of laser-textured surfaces to enhance Ti6Al4V surface wear performance. The sample underwent laser texturing based on pre-set parameter values at 15 W power at a laser scanning speed of 200 mm/s with a frequency of 50 kHz. The surface morphological and topological profile of laser-textured Ti6Al4V was characterized with also the surface microhardness. A comparative appraisal of wear rate (WR) and coefficient of friction (COF) for related samples of as-received Ti6Al4V and laser-textured Ti6Al4V was performed under dry and oil sliding conditions. The results revealed that the formation of oxidation due to the frictional force and plastic displacement plays a role of abrasive to the laser-textured surface and may result in increasing the COF. The wear rate of the laser-textured surface of Ti6Al4V exhibited 88.31% improvement compared to the as-received Ti6Al4V in the dry sliding wear test. It was proved that Ti6Al4V could benefit from LST to gain effectively enhanced wear performance.
Wear Behaviour of Additive Manufactured Aluminium Alloy ER 5356 M. Faris Akmal Md. Azlin, Ahmad Baharuddin Abdullah, Ramdziah Md. Nasir, R. Rajendran, Shahir Y. Mohd Yusuf, Zuhailawati Hussain Materials Science Forum, 2023 In the automotive industry, parts are mostly made from aluminium alloy due to its lightweight properties and high corrosion resistance. However, the drawback is that the aluminium alloy is easily worn due to wear and friction and will end up in the scrap yard. In order to salvage the aluminium component, the worn part can be repaired. Currently, wire arc additive manufacturing (WAAM) offers flexible remanufacturing of the worn part. However, the wear behaviour of the additively manufactured part needs to be studied first to improve the wear performance of the material. In this study, the gas metal arc welding (GMAW) or MIG-based WAAM machine was utilised to produce a 3D profile from the available aluminium alloy wire grade ER 5356. The wear test was carried out in accordance with ASTM G-99, using a pin-on disc in both dry and wet sliding conditions. It was found that on dry sliding, the specific wear rates are decreasing from 5.3632 x 10-11 mm3/Nm to 4.3496 x 10-11 mm3/Nm and 4.1513 x 10-11 mm3/Nm as the speed increases from 200 to 400 RPM at the constant 20 N load. Meanwhile, for wet sliding, it has been observed that the specific wear rate increases as similar speed values are used in dry sliding conditions, which are 6.8122 x 10-12 mm3/Nm, 1.1931 x 10-11 mm3/Nm and 3.7561 x 10-11 mm3/Nm with a similar constant 20 N load. Next, the coefficient of friction for dry sliding shows that as the speed decreases. In contrast, for wet sliding, it is observed that the coefficient of friction increases.
