Abstract

Due to the highly brittle structure of polyurethane (PU) foam, a specialized clamping mechanism is required to consider the material's strength and hardness to avoid damaging the workpiece and to withstand the cutting forces during milling and machining. Using a polymer as an alternative for creating clamping tools with characteristics similar to PU foam offers a promising solution. The slightly harder polymer material is expected to address the need for a gripping tool that will not harm the PU foam upon application. The VDI 2221 method, a structured approach to the design and coordination of evolving design techniques, is employed in this study. The advantage of this methodology lies in its ability to adapt continuously through research. A comparative analysis of two design models produced via 3D printing reveals that Design 5 exhibits superior strength under increased stress. Moreover, Design 5 is more effective in gripping the workpiece, as a single gripper can withstand cutting forces from two directions simultaneously, reducing material deformation. This advancement is expected to minimize the risk of material damage during the machining process. This research's novelty lies in applying an optimized polymer clamping device for PU foam, ensuring improved performance and reduced damage during machining.

Abstract

Kepuasan pelanggan dapat tercapai dengan kualitas produk yang baik. Sistem pengendalian sangat diperlukan untuk menjamin mutu suatu produk. Metode desain VDI (Verein Deutcher Ingenieure) 2221 digunakan untuk mencari solusi terbaik, optimalisasi penggunaan material, dan optimalisasi teknologi. Tahapan perancangan cover dinamometer menggunakan VDI 2221 adalah klarifikasi tugas, perancangan konseptual, perwujudan konsep, dan perancangan detail. Proses pembuatan, perakitan, pemasangan, dan pengoperasiannya relatif mudah. Yang terpilih adalah varian desain 3 dengan proses 3D printing PLA karena lebih kuat, murah, dan mudah dari varian desain lainnya. Dinamometer menggunakan loadcell sebagai sensor berat dan arduino uno sebagai controller. Beban penyayatan yang terbesar terdapat pada sumbu Z, semakin besar kedalaman pemakanan semakin tinggi beban penyayatan.

Abstract

Broiler house heaters play a crucial role in maintaining optimal temperatures during the brooding phase to support optimal growth. However, conventional heaters such as the Super Saver Heater and Heater Handmade have limitations in terms of energy efficiency and heat distribution. This study aims to analyze the performance of the proposed heater in three key aspects: heating rate, heat distribution, and fuel consumption efficiency, and compare it with conventional heaters. The results indicate that the proposed heater increased the temperature from 26°C to 53°C within 2 minutes, with an average heating rate of 13.5°C per minute, outperforming conventional heaters. Heat distribution was more uniform, ensuring stable temperatures at various measurement points within the broiler house. In terms of energy efficiency, the proposed heater consumed only 0.5 kg of LPG in 6 minutes, significantly lower than the Super Saver Heater, which required 1 kg of LPG. Overall, the proposed heater demonstrated superior energy efficiency, faster heating, and more stable heat distribution, making it a more effective alternative to conventional heating systems used in broiler farming.

Abstract

This study presents the redesign of a machine vice used in the Great D1 universal grinding machine, to improve manufacturability, reduce weight, and minimize production costs. The redesign process followed the structured VDI 2222 product development methodology, which includes four phases: task clarification, conceptual design, embodiment design, and detailed design. Through a systematic evaluation of design variants using technical and economic criteria, the final concept was selected and refined using CAD modeling and CNC-oriented manufacturing strategies. The resulting design maintained functional performance while achieving a weight reduction of over 30% and a machining time reduction of more than 50%. Material cost savings were also achieved by using a hybrid structure, with cast iron for the base and aluminum for the movable components. Overall, the total production cost was reduced by approximately 41.8%. In addition to economic benefits, ergonomic improvements such as modular part construction and improved accessibility were realized. These outcomes demonstrate that the structured application of VDI 2222 enables effective redesign of legacy equipment and provides measurable improvements in cost, usability, and production efficiency.
