This project proposes a Closed Loop Manufacturing process with physics-based simulation models, onlinemonitoring, and real-time process control in accordance with Industry 4.0 principles. The machining processwill be simulated in a virtual environment ahead of physical production and stored in the cloud or in adatabase. Real-time machining information, such as cutting force and vibration, will be obtained from inherentCNC (Computer Numerical Control) system data. The pre-simulated result and real-time measurement will beused in conjunction to adjust the machining conditions for suppressing chatter vibrations, preventing excessivetool wear, and avoiding machine overloads, while minimizing the production cycle time. As a result, aso-called digital twin machining system (i.e. combination of simulation and real-time) will be developed withcore functionalities in simulation, monitoring, and self-optimization.Specific aims of this project include: (1) Identification of tool tip dynamics using spindle current for chatteravoidance; (2) Online tool wear monitoring using the feed drive current; (3) Trajectory planning and feedrateoptimization for productivity increase; (4) Identification of feed drive dynamics for cutting force monitoring;and (5) Integration of the algorithms into a commercially viable machining simulation and monitoringsoftware.The project results will be used to reduce machining time and part scrap rates by enhancing intelligentmachining feature. A commercial product will be developed and applied for high volume production, as well asfor low volume and highly customized type of parts. The project is expected to benefit key manufacturingsectors such as aerospace, automotive, industrial machinery, and biomedical devices.

该项目提出了一种基于物理模拟模型、在线监测和符合工业4.0原则的实时过程控制的闭环制造过程。加工过程将在物理生产之前的虚拟环境中进行模拟，并存储在云或数据库中。实时加工信息，如切削力和振动，将从固有的数控系统数据中获得。预先模拟的结果和实时测量将被用于调整加工条件，以抑制颤振，防止过度磨损，避免机器过载，同时最大限度地减少生产周期时间。该项目的具体目标包括：(1)利用主轴电流识别刀尖动力学以避免颤振；(2)利用进给驱动电流在线监测刀具磨损；(3)轨迹规划和进给速度优化以提高生产率；(4)识别进给驱动动态以监控切削力；以及(5)将算法集成到商业可行的加工模拟和监控软件中。项目成果将用于通过增强智能加工功能来减少加工时间和零件废品率。将开发并应用于大批量生产的商业产品，以及用于小批量和高度定制化类型的零部件。该项目预计将使航空航天、汽车、工业机械和生物医疗设备等关键制造业部门受益。
