Availability of Manufacturing data resources in Digital Twin

Data and information are the basis of the integrated manufacturing environment. The latest, synonym of the integrated manufacturing environment is a digital twin. The concept of a digital twin has grown profoundly in recent years. Several models and frameworks are suggested to create a digital twin in manufacturing. Various information and data flows are involved in any manufacturing case. Diagnosis and gather required data and information is the first and basis of creating digital twin. Data ownership is a significant issue because of the large amount of isolated data islands and due to different data ownership relationships of the whole production chain. This study focuses on the ownership paradigm in manufacturing and digital twin. The reliable data resources in manufacturing the metal-based products are recognized. Available and unavailable data in the turning process are studied and classified in general form to cover every condition as a case study. (C) 2020 The Authors. Published by Elsevier Ltd.
