Data analytics for energy consumption of digital manufacturing systems using Internet of Things method

摘要

The topic of ‘Industry 4.0’ has become increasingly popular in manufacturing and academia since it was first published. Under this trending topic, researchers and companies have pointed out many related capabilities required by current manufacturing systems, such as automation, interoperability, consciousness, and intelligence. To achieve these capabilities, data is considered the vitally important connecting media that integrates different manufacturing objects and activities. Additionally, sustainability is one of the most important research areas of Industry 4.0. Although modern digital manufacturing systems are becoming increasingly automated, the issue of sustainability still attracts attention, and is related to many processing factors that are present in a wide variety of systems. As a result, defining the energy consumption behaviour of digital manufacturing systems and discovering more efficient usage methods has been established as a crucial research target. In this paper, data analysis methods are proposed to facilitate better understanding and prediction of the energy consumption of digital production processes under an Internet of Things (IoT) framework. A Selective Laser Sintering (SLS) system is applied as a case study, in which a variety of real-time raw data is collected within machine logs from this ongoing Additive Manufacturing (AM) system. The machine data logs are combined with the product layout data and analysed using three data analysis techniques: linear regression, the decision tree method and the Back-propagation Neural Network method. The future work is introduced in order to complete this research.
