Abstract

This study presents a strength analysis of SUS304 and SUS440 stainless steel materials in the context of their suitability for piping applications in Deionized (DI) water systems. Stainless steel materials, particularly SUS304 (austenitic) and SUS440 (martensitic), are often considered for piping systems due to their durability, corrosion resistance, and mechanical properties. The objective of this research is to evaluate and compare the tensile strength, corrosion resistance, and long-term performance of these two materials when exposed to the specific conditions of DI water environments. SUS304 is known for its excellent resistance to corrosion, making it a widely used material for pipes and fittings in systems that transport water, food, and beverages. Its superior formability, high ductility, and resistance to oxidation at ambient temperatures have made it a popular choice for water distribution systems. In contrast, SUS440 offers higher hardness and wear resistance, which is particularly advantageous for components subjected to high mechanical stress. However, its corrosion resistance is generally inferior to that of SUS304, particularly in environments exposed to chlorides and other corrosive agents commonly found in DI water. The strength analysis in this study involved testing the materials for tensile strength, hardness, and resistance to corrosion under simulated DI water conditions. Both materials underwent mechanical testing, including tensile testing, microhardness testing, and accelerated corrosion testing. The results show that SUS304 demonstrated superior corrosion resistance, making it more suitable for DI water systems, where prolonged exposure to moisture and trace chemicals could lead to degradation. SUS440, while showing higher tensile strength and hardness, exhibited lower corrosion resistance, which could lead to material failure over time when exposed to DI water. This study concludes that SUS304 is the more appropriate material for piping in DI water applications due to its superior corrosion resistance and adequate mechanical strength for typical water transport systems. However, SUS440 may be considered for specific components requiring higher wear resistance but with additional measures to address potential corrosion issues.

Abstract

In the machining process, the speed grip of the CNC Router spindle on the surface area of the activity entity is very closely monitored and the physical quality of the cutting surface is also on the amount of cutting speed, thickness of the tape and the strength of the film. The aim of the study is to understand the speed grip of the CNC Router on the surface mill system on the surface surface of the activity entity. using spindle speeds of 1000 rpm, 1200 rpm and 1400 rpm. The equipment and materials in this study are aluminum and measuring equipment. Based on the results of the visual study, it was found that the largest and most aggressive flat body was seen at a spindle speed of 1000 rpm, and a stable flat body was seen at a spindle speed of 1200 rpm, then the smallest or strongest flat body was seen at a speed of 1400 rpm while the data from studies using Roughness Tests, it shows that the average Ra point at a spindle speed of 1000 rpm is 0.33 um, at a spindle speed of 1200 the Ra point is 0.30 µm, and at a spindle speed of 1400 rpm the Ra is 0.29 µm. From the results of the study, it was found that the smaller and higher the spindle rotation, the grip on the physical surface on the face mill of the experimental entity and the higher the speed of the spindle, the smoother the surface, and vice versa, the smaller the spindle rotation, the more aggressive the surface. Keywords: Spindle Speed and Surface Roughness.

Abstract

Friction welding is a solid-state welding technique that generates heat from friction and pressure to join two metals together. Friction welding includes various techniques, such as friction stir welding, linear friction welding, and continuous drive friction welding. This literature review examines various friction welding techniques, the welding defects that may arise among these methods, and identifies the most appropriate friction welding technique for connecting pump shafts composed of Aluminum and Copper with a circular cross-section, as fusion welding is not applicable for joining Aluminum and Copper. A primary reason is the substantial difference in melting temperature between Aluminum and Copper, approximately. 400 degrees Celsius. Based on the literature review, the outcomes of friction welding may be influenced by rotational speed, duration of pressure, axial pressure force, and the properties of the materials utilized. Employing a case study of the pump shaft, it was determined that the continuous drive friction method is the optimal technique for bonding Aluminum and Copper in the pump shaft, as the temperature distribution can be uniform across the entire weld joint surface. This situation will lead to a more uniform microstructure and weld joint quality.

Abstract

Material replacement in a product is a fatal thing for a company, because it will have a big impact on production operations, including the regulation of machine parameters, product quality, and production costs themselves. The difference in the specifications of the two materials will have a big impact on the parameter setting of the injection molding machine including the quality of the products it produces. Therefore, finished parts from new materials must be tested first to ensure that parts with new materials have no problems during the production process or customers later.

Abstract

This study aims to develop an economical, efficient, and precise automatic fabric cutting machine to improve productivity and quality in small to medium-scale textile industries. Traditional manual cutting methods often lead to inconsistent results, lengthy cutting times, and human error, which can hinder production efficiency. The research involves designing the machine, selecting key components, assembling the tool, and testing its performance on various fabric types. Results show that the automatic fabric cutting machine enhances cutting speed by up to 50% with consistent precision, while also reducing fabric waste caused by cutting errors. The study concludes that this machine offers a viable solution for textile industries to improve efficiency and quality at a lower cost compared to commercial machines. Further improvements are suggested to include automated pattern-cutting capabilities and better fabric compatibility.

Abstract

The oil that is so widely circulated on the market and so many advertisements placed in the TV media makes us as consumers confused about what kind of oil is suitable for use in the daily life of consumers The purpose of this research is to find out how far the maximum mileage of each viscosity value in the oil that is tested for different viscosity levels is also when using fuel with different octane values. After trying all the oils that I used during the testing process, it can be concluded that the oil that has a viscosity code SAE 20w-50 is more efficient in fuel use than oil with viscosity codes such as 10w-30 and 15w-40, the results that I obtained the longest distance by using 1 liter of fuel consumption, the farthest distance that can be traveled with fuel with 88 octane, which is 54.3 Km at a speed of 40 km/h and fuel consumption rate each hour is 0.740 liters/hour and for a speed of 60 km/h and 80 km/h the distance that can be traveled is 52.1 Km and 47.7 Km fuel consumption is 1,174 liters/hour and 1,711 liters/hour and for fuel use with an octane value of 95 which is 63.4 km at a speed of 40 km/h and for a speed of 60 km/h and 80 km/h 59.6 Km, fuel consumption per hour is 0.637 liters/hour and 1.015 liters/hour and 1.0882 liters/hour respectively that here seen that the faster a vehicle will be the greater the fuel consumption that will be used.
