Abstract

Digital twins enable the intelligent operation of computer numerical control (CNC) machine tools from which a wide range of data can be collected using sensors and other Internet of Things (IoT) devices. Creating a valid digital twin for a specific purpose requires identifying and specifying the right types and quality of data. However, there are challenges, such as unlabeled data and a lack of clarity on the sufficiency of data required to build a digital twin for a specific purpose. This paper discusses the data types, sources, and acquisition methods for creating digital twins for machine tools with different capabilities. Depending on the purpose, any digital twin can be categorized as descriptive, diagnostic, predictive, prescriptive, and autonomous. Data requirements for each of these categories are discussed. This paper can be used as a guide for developing and validating different types of digital twins for CNC machine tools.
