The purpose of this study is to support eco-design ideas and sustainable manufacturing techniques by examining the energy consumption related to drilling holes for different furniture connections. The experimental model is a simple piece of furniture made from birch plywood with three different types of joints. Eccentric joints, confirmat screws, and dowel measurements of energy consumption with a CNC drilling and milling machine show different values for every kind of connector. The energy consumption was measured using a portable power quality analyzer, specifically the PQ-box 150 manufactured by A:Eberle GmbH & Co. KG Nürnberg, Germany. This device likely adheres to industry standards for energy measurement, ensuring accurate and reliable results. The measurement process involved recording energy consumption at different stages of the machining process, allowing for the analysis of specific cutting work and total energy consumption for various joint types. Dowels exhibit the lowest energy consumption at 0.105 Wh for one furniture joint, confirmat screws at 0.127 Wh, while eccentric joints, despite their higher energy consumption (0.173 Wh), offer enhanced transportability and assembly flexibility of a piece of furniture. Specific cutting power for one selected piece of furniture was 227.89 J/mm for dowels, 190.63 J/mm for eccentric joints and 261.68 J/mm for confirmat screws.
本研究的目的是通过研究不同家具连接件钻孔相关的能源消耗，来支持生态设计理念和可持续制造技术。实验模型是一件由桦木胶合板制成的简单家具，带有三种不同类型的接头。使用数控钻铣床对偏心接头、定位螺丝和暗榫的能源消耗进行测量，结果显示每种连接件的能耗值都不同。能耗是使用便携式电能质量分析仪进行测量的，具体是德国纽伦堡的A:Eberle GmbH & Co. KG公司生产的PQ-box 150。该设备可能符合能源测量的行业标准，确保结果准确可靠。测量过程包括记录加工过程不同阶段的能耗，以便分析各种接头类型的特定切削功和总能耗。对于一个家具接头，暗榫的能耗最低，为0.105瓦时，定位螺丝为0.127瓦时，而偏心接头尽管能耗较高（0.173瓦时），但能提高家具的可运输性和组装灵活性。所选一件家具的特定切削功率，暗榫为227.89焦/毫米，偏心接头为190.63焦/毫米，定位螺丝为261.68焦/毫米。
