This study develops an AI-based energy consumption prediction and precision carbon footprinting technology for machine tools to facilitate the digital zero-carbon transition. Utilizing the VMX IIoT platform and current sensors, the system extracts 34 controller features and energy data in real-time. Key features are selected via Random Forest, and a Deep Neural Network (DNN) model is constructed for prediction. Results demonstrate high accuracy, with error rates below 3% for both CNC milling and stamping equipment. Through an online monitoring system and visualization interface, manufacturers can monitor real-time energy usage and carbon footprints, optimizing machining parameters to meet international sustainability regulations and advancing smart green manufacturing.
