Digital twin (DT) is a core technology that enables the integration among physical machines, tools, material handling and warehousing, and real-time manufacturing decisions. In this study, a DT framework is proposed for the real-time monitoring of conventional machines to connect isolated machines to an interconnected system and monitor machine conditions in real-time. We implement a DT for a die cutting machine. A dashboard-based mission centre is created to display the real-time condition of the machine. The mission centre is composed of three main functions: real-time machine monitoring, overall equipment effectiveness, and order scheduling. Compared with existing approaches with a barrier of high investment and/or high design complexity, this study proposes an economic DT framework composed of conventional machine structure but has a tolerable level of industrial Internet of things capability.

数字孪生 (DT) 是一项核心技术，可实现物理机器、工具、物料搬运和仓储以及实时制造决策之间的集成。在这项研究中，提出了一种 DT 框架，用于对传统机器进行实时监控，以将孤立的机器连接到互连系统并实时监控机器状况。我们为模切机实现了 DT。创建了一个基于仪表板的任务中心来显示机器的实时状态。任务中心由三个主要功能组成：实时机器监控、整体设备效率和订单调度。与具有高投资和/或高设计复杂性的现有方法相比，
