Digital twin technology is transforming CNC micro machining machining operations by creating virtual replicas of physical machines and processes. This article explores how digital twins enable real-time monitoring, predictive maintenance, and optimization of CNC machines. Topics include the integration of IoT sensors for data collection, AI algorithms for predictive analytics, and cloud-based platforms for remote access and collaboration. By simulating machining scenarios in a virtual environment, manufacturers can identify potential inefficiencies, optimize tool paths, and simulate production outcomes before physical machining begins. As digital twin technology evolves, its impact on CNC machining is expected to enhance productivity, reduce downtime, and drive continuous improvement in manufacturing efficiency and quality.
