Abstract

Nowadays, the process of metal forming in the machining industry and welding workshop is developing very rapidly especially in the plate bending process. The bending process is the formation of metals which generally use plates or rods of both ferrous and non-ferrous metal materials by bending, which in the bending process will cause stretching or stretching on the neutral plane axis along the bending area and produce a straight bend line. The use of appropriate technology machines has been widely used to increase productivity, efficiency, and effectiveness in the production process for community businesses, especially those in the regions. One of the appropriate technologies that might be applied in the bending process is a hydraulic jack press that is equipped with a press tool. Press tool is one type of product forming, cutting and bending tools from the basic material of sheet plates whose operations are using a press tool. The results of the design of press tool bending tool V have a length of 300 mm bending line, 33 mm bending width, 110 mm spring height, free step distance of 19 mm. The punch angle used is 85⁰ with the punch radius used is 1.5 mm while the die angle is 85⁰. The selected punch and die material is Steel AISI 1045 HV HR.

Abstract

Wire cut is a high-tech machining process and can be used to make high-precision products. This study aims to analyze the results of the workpiece surface and study the effect of current strength and wire speed on wire cut machining of EMS 45 on the surface roughness of straight gears. The results analyzed were the surface roughness values obtained by testing the surface roughness. The variations in the current used were 3 amperes, 5 amperes, and 7 amperes, while the wire speed used was 8 mm / min, 10 mm / min, and 12 mm / min. In the wire cut machining process, brass cutting materials are used with a wire diameter of 0.25 mm. The results showed that the greater the current and wire speed used, the lower the surface roughness value, conversely the smaller the current and the wire speed used, the higher the surface roughness value. The results of data analysis using the ANOVA analysis method, correlation, and regression get the optimal conditions for obtaining low surface roughness values and fast cutting time, namely at a current of 7 amperes with a wire speed of 10 mm/min.

Many forms of technological development aim to answer the need for human work efficiency, so an effective technology development effort is very necessary. As the times progress, of course, there are many changes, especially in science and technology, which may have shifted completely in the industrial area, meaning that in this change it is necessary to require extra operations, namely human labor replaced by machine power. One of them is a plate bending machine or what is called a bending machine. The purpose of this program according to the formulation of the problem above is to maximize the drive system and bending system so that the bent plates form a 90° angle. This research includes several things such as sketching or drawing of bending tools to be modified, as for what we modified, namely the replacement of the top and a larger bottom plate so that the pressing system functions properly, as well as the replacement on the spring so that it matches the load received by the spring. After determining the form of the construction design of the plate bending tool, then determine the concept of each main component of the plate bending tool in order to get maximum and good bending results. The data from the test results of this portable bending tool were tested with different plate thicknesses, namely 2 mm, 3 mm and 4 mm plates. Tests were performed on each thickness using the maximum bending line. Based on the tests carried out using this bending tool that the drive system works optimally and the bending system works properly and the maximum bending on a plate with a thickness of 4mm can be bending at the right angle of 90° is said to work optimally.

Abstract

The creation of a soil-loosening device that works well on dry terrain is the goal of this study. With this equipment, perhaps, human labor in construction and agriculture will be reduced and productivity will rise. In the machine assembly process, virtual assembly is carried out using Autodesk Fusion 360 software prior to the actual assembly phase. During assembly, the mounting frame for the combustion engine is joined to the main frame. Furthermore, sprockets are mounted on the two axles and wheels, and belt tensioners are added. This machine's blade is used to swiftly loosen the dirt. An area of thirty square meters was tested by machines on dry land, and each test took an average of 229.3 seconds to complete. The machine's time efficiency is greater than that of the earlier variants. In addition, factors including longevity, running costs, simplicity of maintenance, and environmental effect need to be carefully considered in this study. This development tool has a great deal of potential to improve the efficiency and productivity of the dry land soil loosening process. The research findings are expected to contribute to technological advancements in Indonesia's building and agriculture sectors.

Abstract

In the metal-cutting industry, the precision of the metal-cutting process is of paramount importance. Errors in the metal-cutting process not only lead to damage to the cutting tool but also result in the production of low-quality materials. The incorporation of insert materials in the cutting process is aimed at maintaining cutting precision and achieving superior results. This research seeks to investigate the impact of the cutting process utilizing grade KC5410 cutting insert under minimum quantity lubrication (MQL) Conditions. In this study, machining tests were conducted using the ALPHA 1350S 2-axis computer numerical control (CNC) lathe machine under MQL conditions, employing cutting tool inserts UTi20T supplied by Mitsubishi. Two types of tools were utilized in the cutting process, namely UTi20T. Critical aspects such as cutting force, total power consumption, surface roughness, and tool life were analyzed to provide comprehensive insights into the efficiency of the cutting process. The findings of this study significantly contribute to the understanding of how the integration of Grade KC5410 cutting inserts under MQL conditions can enhance the overall efficiency of metal-cutting operations. The successful machinability assessment was conducted by implementing sustainable machining practices.

Abstract

Natural fibers are increasingly used in various industries due to their eco-friendly properties and cost-effectiveness. However, current methods for testing the mechanical properties of these materials, such as tensile strength, often face limitations in accuracy and efficiency. This study aims to develop an innovative digital-based fiber tensile testing apparatus to enhance the precision of tensile testing. The research involves the design and construction of the apparatus, utilizing components such as ST37 steel, stepper motors, and Arduino technology. The apparatus was tested using two types of natural fibers, Cocos nucifera L. (coconut fiber) and Sansevieria, to assess their tensile properties. The results showed that although Sansevieria fibers have a smaller diameter, they exhibited higher tensile stress compared to coconut fibers. The developed digital testing apparatus enables more accurate and efficient fiber testing, contributing to the development of stronger and more sustainable materials for industrial applications. The findings of this study highlight the potential of advanced testing equipment in supporting the use of natural fibers in manufacturing and environmental sustainability.
