Mohd Azman Abdullah — 2025-06-30

The Smart Wire Cutter Mechanism deals with the same old problems of manually operated wire cutting, such as inefficiency and even danger to operators. The inconsistent lengths of wires from manual operations have often caused high material waste that requires expensive and time-consuming reworks. The study intends to counter these problems by developing an automated wire-cutting system designed to enhance precision, smoothen efficiency, and hence reduce injury risks greatly. The main aims of the project are minimization of safety risks, improvement in accuracy with accurate control mechanisms, and an 80 percent cut in wire-cutting time. Precisely fabricated to handle wires of 1.25 mm gauge, the machine fabricates the said gauge of wire with high precision. The automated system was able to achieve an astonishing testing accuracy of ±0.5 mm, reducing the inconsistencies associated with manual cutting by a great amount. The key components include a stepper motor and a metal extruder mechanism that plays an important role in the automatic feeding of the wire to the cutting blade with consistency and accuracy at every cut. Besides the core functionality of cutting, the Smart Wire Cutter Mechanism has safety enhancements that make it much safer compared to manual methods. The system features a safety option during the operating process to minimize the possibility of injury. In addition, the machine is designed with an inbuilt conveyor mechanism where the cut wires are automatically transported to further smooth the entire process without much need for human interaction. It saves not only time but also assures a much safer and efficient work environment. The result of this project depicted the following productivities: the system greatly reduced the time cut and increased efficiency in the overall operation process. The project was a milestone in wire-cutting technology for industries relying heavily on precision and efficiency in wire processing. It fulfills some very important industrial requirements by providing a solution that improves safety and boosts productivity, marking a major leap in automation related to wire processing.

APPLICATION OF TAGUCHI-PARETO-DEMATEL METHOD TO OPTIMIZE THE THERMAL SPRAY HIGH-VELOCITY OXY-FUEL (HVOF) PROCESS PARAMETERS USING 67NI18CR5SI4B COATING

In contemporary technology, for the parameter of corrosion erosive wear, the responses of metal-based coatings such as FeCrCoAlTiB, FeCrNiSiB and 67Ni18Cr5Si4B among others, in high-velocity oxy-fuel spraying, have been investigated from both optimization and X-ray photo-electron spectroscopic perspectives. Notwithstanding, the expected utility of these perspectives, the interaction among the parameters of the spraying process is unexplored. Using data from the literature, this study presents a new method, the Taguchi-Pareto-DEMATEL method to capture interaction among the three key parameters of spray distance, velocity of spray and powder flow rate. The results show that the Taguchi-Pareto method exhibited an optimal parametric setting of S₃V₁P₃, indicating 0.3 m of spray distance, 800 m/s of the velocity of spray and 50 g/min of powder flow rate. There is a concurrence of ranking in 33.3% of the instance where our ranks and Dinh et al.'s ranks conflicts as (2,1,3) and (2,3,1) for spray distance, the velocity of spray and powder flow rate, respectively. Furthermore, our results show that S, V and P are neutral along the net effect perspective. They are all equal from the prominence viewpoint. The contribution of this study is the exploration of parametric prioritization in combination with a method of analyzing the interdependence of the high-velocity oxy-fuel spraying parameters for the 67Ni28Cr5Si4B coating.
