    Fault Tree Analysis (FTA) is one of the tools used by various industries such as aerospace, oil and gas, automotive and other high-hazard risk industries to consider the rationale that leads to undesired condition or occurrence. It can also be used to reduce and maximize capital in the production process. This case study evaluates the issue by using the fault tree analysis (FTA) to increase the performance of the manufacturing cycle of a local business in Selangor, Malaysia. The approach helps to define the cause and impact of the product in the production process. The company has been searching for efficient ways to improve the productivity of its output. Potential causes and consequences have been identified during the study period. Based on the results, the company will consider finding strategies for managing input and output of production.

    The use of lightweight Aluminium Alloy 7075 (AA7075) in aerospace and automotive industries is increasing due to its exceptional properties, such as high strength, good fatigue resistance, and excellent strength-to-weight ratio. However, this alloy is difficult to machine due to high ductility and heat generation during cutting. Cutting fluids are commonly used to deal with these problems, although they raise environmental concerns. The research aims to enhance drilling efficiency for AA7075, considering environmental impacts, through a greener method, a chilled air system. Their impact on tool wear and cutting force was evaluated through spindle speed, feed rate, and nozzle types by adopting the Taguchi method. Chisel edge wear was discovered to be a major contributor to tool wear. Lower feed rate and slower spindle speed using dual nozzle yielded better tool wear and cutting force performance. These findings provide feasible recommendations for industry practitioners seeking to employ eco-friendly chilled air systems to achieve optimal drilling efficiency for this type of material.

    Aluminum alloys are popularly used in the aerospace industry due to their lightweight and high strength-to-weight ratio. However, cutting these alloys can result in various machinability issues such as tool wear, built-up edges, and material adherence on the cutting tool. To address these issues and minimize the use of lubricants, researchers are exploring alternative greener techniques. One such technique is the use of nano lubrication technology. In this research, the consequence of three cutting techniques - dry cutting, minimum quantity lubrication (MQL), and MQL dispersed with graphene nanoparticles - was experimentally studied to assess their impact on hole quality, surface roughness, and the number of holes drilled. The findings showed that the addition of graphene nanoparticles improved roughness quality, reduced tool wear, and increased the number of holes drilled, but had less impact on hole accuracy. This study highlights the importance of nanoparticles in enhancing the machinability of aluminum alloys and offers promising avenues for future research in this area.

    This paper describes the suitability of a loudspeaker to be used as a linear alternator. The present study is intended to clarify experimentally that the ability of loudspeaker to detect a frequency of sound wave by applying the sound into a resonator with the different of length. The result of the experiment will determine the suitable length of resonator that give the best reading. The linear alternator is a linear motor which commonly used as an electrical generator. It is a type of alternating current electrical generator. The function of an alternator is to convert mechanical energy to electrical energy. The linear alternator operate under the principle of electromagnetic induction. Unlike linear alternator, other alternator work in rotary motion while the linear alternator work in linear motion. Electromagnetic induction is a result of an electromotive force across an electrical conductor cause by the dynamic interaction with magnetic field. The data of the experiment was conducted based on the three length of resonator. Based on the experiment, all three resonator give the best reading when the operating frequency of 200 Hz was used. The peak to peak voltage recorded for 100 mm length was 776 mV while the peak to peak voltage recorded for 150 mm length was 824 mV. The last resonator give the reading of 776 mV. For the decibel reading, the 100 mm resonator give the reading of 100.2 dB. The resonator of 150 mm give reading of 98.5 dB and the 200 mm give decibel reading of 99.8 dB. For the experiment with heat engine, the highest peak to peak reading is 40.7 mV and the decibel reading is 110.9 dB.

    The quality of cutting depends most on the cutting tool condition. Towards having a good quality finish, cutting tolerance becomes a major concern, especially when machining at micro-scale where highly precise cutting is desired. This research investigates the size-effect during the micro-milling of Ti-6Al-4V under dry condition where the observations were made on cutting edge rounding (CER) and workpiece surface roughness. The result showed that the lower the feed rate, the greater rounding on the cutting edges were observed. Similar trend in result was obtained when measuring the surface roughness. The best feed rate for both observations was at 60 mm/min, where this setting has brought the mechanism to shearing, as the ratio between undeformed chip thickness and cutting edge radius started at 1.

    The most fire-related fatalities are due to the smoke inhalation of the toxic gases. It is related to the victims being trapped in the building when the building was on fire. It was also reported that major deaths from fire related are from the toxic gases inhalation produced by the fire while the deaths due to fire flames and burning was about one third of the total deaths. The access to the exit door was blocked and they could not exit through the window due to the permanent grille installation. It was well aware that most Malaysian homeowners installed grilles on their house windows or doors for security reason since there are lots of break-ins incidences. To overcome the issue, this work introduces a window grille with keyless locking system. The design incorporated keyless system that can be operated or opened without a key. Several designs for implementing this solution have been described. These designs are divided into three sections, which is a grille design, expansion designs which use to accommodate a wide range of window-sized and keyless locking systems. The size and type of grille suitable for Malaysian residents as well as the more efficient keyless locking system has been studied in detail using the method of case study and survey method. Step of patent research, market analysis and benchmarking are used as methods for collecting reference data. The most effective fire escape window grille keyless locking system has been studied and designed from this project. An important factor in designing a fire window grille is the design that can be opened and does not require a key operation. The results of the design and analysis tested are presented such that they can be used as an aid to the design of fire escape features.

    Additive manufacturing is a process that makes three-dimensional object layer by layer. There are many different types of 3D printer and the most commonly used is Fused Deposition Modeling (FDM). There is a need for a new material for Acrylonitrile Butadiene Styrene (ABS) FDM filament to improve filament strength and reduce the usage of plastics. From literature, there are limited studies available on making 3D printer filament reinforced by recycled carbon black. The limitation hinders the potential of using this material in new applications. In this study, recycled carbon black powder (rCB) was added as a filler reinforcement to enhance the properties of ABS. Parameters considered in this study were percentage of filler weight loading and filler size. Tests and characterisation used in this study were tensile test, thickness test, surface roughness test, scanning electron microscopy, density test and water absorption test. There were improvements in mechanical properties such as tensile test and elasticity of the filament compared to the pure ABS plastic. The higher filler percentage can improve the elasticity of filament and lower filler percentage can improve the strength of the filament. The findings could help in improving marketability status and commercialisation potential of rCB reinforced ABS filament for FDM applications.
