Abstract

TRUMPF TrumaBend V85S CNC Bending Machine can be used to get good bending results. But in every bending process there are several problems encountered, one of which is springback. Springback can be influenced by several parameters such as material thickness, compressive force, and bending angle, and the radius. Springback can be avoided by examining which parameters have the greatest influence. One way to improve the quality of bending products from springback is by parameter optimization. Parameter optimization is a technique used in the manufacturing process to produce the best products. Optimization of compressive force, angle, and radius parameters is done to optimize the value that can have a major effect on springback and which parameters are most influential. Design experiments using Box-Behnken with ANOVA to analyze data and performed using the Response Surface method. The results showed that the radius parameter was the only one that affected the ST37 material springback. While the optimum parameter obtained a compressive force of 500 KN, an angle of 120°, and a radius of 3 mm with a springback result of 130,28°.

Abstract

PT. BBI (Boma Bisma Indra) is one of the manufacturing companies, working based on orders from consumers, which starts from the design process (Engineering To Order). The products produced include pressure vessels, condensers, cranes and heat exchangers. The problem that arises is that production has been experiencing delays, one of which is due to labor. Could be because the composition of the number of workers is not right or the workload is not yet suitable. To find out these problems, resource leveling methods are used to optimize / evenly distribute the number of human resources used so that there is no significant difference from the number of workers in each activity, and avoid the possibility of excess labor. In its application this method can use the PDM (Precedence Diagram Method) method. After the leveling of human resources (resource leveling) will then be performed calculations of human resource needs using work load analysis to determine the workload on each work activity. The results showed a labor of 1 person marking, 2 people leave, 2 people drilling, 2 people assembly, and finishing 6 people. With the existing workload produced more labor, namely marking 1 person, cutting 5 people, drilling 3 people, assembling 6 people, and finishing 21 people.
