    The Watermelon Slicer project focuses on the design and development of a mechanical tool to efficiently and safely slice watermelons. The objective is to address the challenges associated with manually cutting large and irregularly shaped fruits, which often pose difficulties in terms of safety, consistency, and time consumption. The proposed device integrates ergonomic design with sharp cutting mechanisms to achieve uniform slices with minimal physical effort. Key factors considered in the design include user safety, ease of use, material durability, and cutting precision. Prototypes were tested under various operational conditions to assess performance in terms of cutting efficiency, slice uniformity, and user comfort. Results demonstrate that the slicer significantly reduces preparation time while enhancing safety compared to conventional methods. The study concludes that the watermelon slicer presents an effective, time-saving solution for both domestic and commercial applications. Future work will involve further refinements to improve the product’s versatility for cutting a wider range of fruits and vegetables.

    Crash box is a vital component for a vehicle in absorbing kinetic energy in the event of a road collision. The thin-walled structure is emerging as a favorable geometry in designing the crash box. This article investigates the energy absorption performance of the corrugated nautilus shell bio-inspired thin-walled structure made of AA6061-T6 aluminum alloy. This structure’s performance was evaluated using finite element analysis (FEA) under quasi-static and dynamic loading conditions in an axial direction, then validated by a quasi-static compression experimental test, which showed satisfactory agreement. The results show that the corrugated nautilus shell bio-inspired thin-walled structure integrated with corrugated grooves reduced peak crushing force (PCF) by 17.9% and increased specific energy absorption (SEA) by 1.3% and crush force efficiency (CFE) by 17.6% compared to non-corrugated design. It can be concluded that the proposed nautilus shell bio-inspired thin-walled structure integrated with corrugated grooves has the potential to replace conventional hollow square designs in vehicle crash box applications.

    This task involved numerical analysis study to investigate the air flow distribution affected by blade distributor arrangement of Multi-Stage Swirling Fluidized Bed (SFB). The current systems is in difference with conventional fluidization systems where the current systems will impart swirling motion to the particle. This study focused on the velocity distribution on blade distributor whereby the influence of blades number (30, 45, and 60) via horizontal inclination angle (10°, 12°, and 15) through multi-stage distributor arrangements, therefore a separate velocity component would be obtained. The numerical simulation, was utilised to compute and analyse the performance outcomes of three velocity components: tangential, axial and radial velocity in an Multi-Stage SFB. From the results of the study, the fluidization systems with high blades number of 60 and blades angle of 15° has shown a significant air flow distribution at both stages. Thus, the major velocity component such as velocity magnitude and tangential velocity in the Multi-Stage SFB have shown a retention uniformity along the radius blade distributor and the air flow inside the system rise more than 40 m/s.

    Titanium alloy Ti-6Al-4V is widely being used in the blades, discs, rings, airframes, fasteners, components, vessels, cases, hubs, forgings and biomedical implants. Nevertheless, the properties of titanium alloys which are low thermal conductivity, low modulus of elasticity and high chemical activity cause it very difficult to machine. Excessive elevated temperature due to low thermal conductivity of these alloys make it favorable for tool wear. In this paper, an experiment using orthogonal array L4 is conducted to explore the effect of cutting parameters e.g. cutting speed, depth of cut and feed rate in terms of surface roughness and tool wear. The cutting tool uncoated carbide is used in performing orthogonal cutting of Ti-6Al-4V in this study. It is found low cutting speed, feed rate and high depth of cut is favourable in producing good Ra and minimum flank wear.

    The development and design of a spring-type fixture play a critical role in enhancing the precision and efficiency of manufacturing processes that require repetitive assembly or testing. This research focuses on the design, and fabrication of a spring-loaded fixture aimed at improving workpiece positioning, alignment, and clamping accuracy in various industrial applications. By integrating a spring mechanism, the fixture provides adaptive flexibility, enabling consistent pressure and secure holding, thereby minimizing operator-induced errors and increasing production throughput. The study presents a detailed analysis of the fixture's mechanical design, including the selection of materials, and dimensions while maintaining cost-effectiveness. Cutting simulations are conducted using MasterCAM software to assess toolpath accuracy and detect potential collisions, optimizing the fixture’s functionality. The results demonstrate that the spring-type fixture achieves significant improvements in repeatability and precision, particularly in industries such as automotive, aerospace, and electronics. This design contributes to the advancement of fixture technology by offering a solution that enhances both operational consistency and efficiency in high-precision manufacturing environments.
