Fixturing technology and system for thin-walled parts machining: a review

《机械工程前沿(英文)》 2022年 第17卷 第4期 doi: 10.1007/s11465-022-0711-5

摘要: During the overall processing of thin-walled parts (TWPs), the guaranteed capability of the machining process and quality is determined by fixtures. Therefore, reliable fixtures suitable for the structure and machining process of TWP are essential. In this review, the key role of fixtures in the manufacturing system is initially discussed. The main problems in machining and workholding due to the characteristics of TWP are then analyzed in detail. Afterward, the definition of TWP fixtures is reinterpreted from narrow and broad perspectives. Fixture functions corresponding to the issues of machining and workholding are then clearly stated. Fixture categories are classified systematically according to previous research achievements, and the operation mode, functional characteristics, and structure of each fixture are comprehensively described. The function and execution mode of TWP fixtures are then systematically summarized and analyzed, and the functions of various TWP fixtures are evaluated. Some directions for future research on TWP fixtures technology are also proposed. The main purpose of this review is to provide some reference and guidance for scholars to examine TWP fixtures.

摘要: A planner for a self adaptable and reconfigurable fixture system is proposed. The system is composed of mobile support agents that support thin sheet metal parts to minimize part dimensional deformation during drilling and milling operations. Compliant sheet metal parts are widely used in various manufacturing processes including automotive and aerospace industries. The main role of the planner is to generate an admissible plan of relocation of the mobile agents. It has to find the admissible locations for the supporting heads that provide continuous support in close proximity to the tool and trajectories of the mobile bases characterized by very high speeds during the relocation phases.

摘要: 动态网络是指其节点和/或链接随时间动态变化的图结构。现有可视化和分析技术主要集中在总结和揭示网络结构的主要演化模式。很少有工作专注于检测动态网络中的异常变化模式,这种情况很少发生,一旦发生,则可能破坏整个结构的发展。本文介绍了第一个可视分析系统RCAnalyzer,用于检测动态网络中子结构的罕见变化。所提系统采用稀有类别检测算法识别异常变化的结构,并在上下文中将其可视化,以帮助专家检查分析结果并标记数据。特别地,引入新的可视化形式,用一系列连接的三角矩阵表达动态网络快照。在每个矩阵上进行层次聚类和最佳树切割,以展示在其周围结构的上下文中检测到的节点和链接的罕见变化。通过案例和用户调研评估该技术。评估结果验证了该系统的有效性。
