Abstract

Solar cells are becoming so common that every industry except PLN is already using them to produce alternative energy. The more solar cells used, the more light intensity meters are needed to calculate the amount of Illumination in a given area. This research entails constructing or implementing software, calculating the float's balance against the impact of waves, and determining how the float distributes load using the Archimedes principle. Electrical construction and chassis buoyancy are included in the design. When the density of water is greater than the density of the object, namely > objects (997 kg/m3 > 46.73 kg/m3), the variables obtained are the total weight of the buoy of 5,044 kg with the distribution of the object force of 49.43 N and the buoyant force of 1046.08 N. then this design produces the required buoyancy force when manufactured and used.

Abstract

Springback is a phenomenon that frequently occurs in bending processes and is detrimental to the manufacturing industry. Typical disadvantages include the incompatibility of the product's final dimensions and the need for additional processing. Indeed, these must also incur additional expenses and result in the inefficient production process flow. Consequently, the analysis of springback is attracted to studies to obtain a bending product that meets expectations. This study examined the springback phenomena on 60 mm x 19 mm x 2 mm aluminium alloy 6063-T5 materials using V-bending processes and approximately 40°, 50°, and 60° punch angles. This study also utilized the die opening and bending force variables, 35 mm and 2500 N, respectively. It was anticipated that these procedures would produce a 6063-T5 aluminium alloy with a bending angle of approximately 90 degrees. The results indicate that the bending angles produced by these processes with the various punch angles are 91.50°, 91.42°, and 91.67°, respectively. It indicates that the excess bending angle was referred to as springback. Consequently, a bending angle of approximately 90° can be obtained on aluminium alloy 6063-T5 using V-bending processes with the set parameters of die opening in 35 mm and bending force in 2500 N, in addition to the punch angle that was reduced based on the known springback value. In addition, it is anticipated that this result will contribute to the development of the manufacturing industry, particularly the aluminium alloy 6063-T5 materials industry, or serve as a reference for other relevant studies

Abstract

This study discusses the phenomenon of spring-back and spring-go in the bending kinematic forming using V-bending dies process and Electrolytic zinc-coated steel sheet (SECC/JIS G 3313) material. The zinc layer on the galvanized steel surface should not be damaged during the material forming process. The zinc layer on the galvanized steel sheet will affect the metal forming process. This study uses an experimental design with four input parameters, namely v-die opening L (mm), punch angle (degree), punch speed (mm/minutes), and bending force (kN). The smallest spring-back was obtained in the 4th test sample: the v-die opening of 35 mm, the punch angle of 40o, the punch speed of 30 mm/minute, and the bending force of 7.50 kN. The minor spring-back degree was 1.67o. Meanwhile, the smallest spring-go obtained in the second sample, namely the v-die opening of 30 mm, the punch angle of 50o, the punch speed of 40 mm/minute, and the bending force of 7.00 kN, the minor spring-go degree of 0.92o was obtained. These results show that the best spring-back degree for SECC/JIS G 3313 material is obtained when the bending process is performed with the v-die bending parameter of 30 mm, punch angle of 50o, punch speed of 40 mm/minute, and bending force of 7.00 kN.
