Abstract Industry 4.0 comprises a set of technologies that allow the interconnection, monitoring, and controlling of manufacturing processes. Today it represents a key point for the modern industry. The current work presents an Industry 4.0 system developed for monitoring and controlling a 5-axis CNC machine center, in real time, through a mobile device, providing important feedback information for users and manufacturers of the machine. Given that response time is crucial in such applications, we conducted an experimental investigation to examine the system latency with distinct database structures, based on SQL and NoSQL. The results suggest that the non-relational structure (NoSQL) presented lower response times and is, thus, best suited for the application in hand. The system allows monitoring and controlling of any CNC machine remotely—given that a middleware for connecting the machine is provided—in real time, presenting new possibilities from the perspectives of machine tool builders and shop floor management.

1 Introduction The so-called third industrial revolution introduced automation at factories and production processes, aided by robots, computers, sensors, and other equipment, although working separately from each other [1]. Today, the Industry 4.0—also known as Smart Factory—aims to establish the fourth industrial revolution by integrating all these systems through databases, using concepts and tools such as internet of things (IoT), cloud computing, and artificial intelligence [2]. It allows the exchange of data regarding the manufacturing process among all machines in a factory (and also geographically separated factories) that in the end will produce smart products [3]. Ideally, CNC and machine should meet the following requirements in order to fully support Industry 4.0: (i) controller architecture, (ii) sensors and systems capable of obtaining information Supplementary Information The online version of this article (https:// doi.org/10.1007/s00170-020-06245-2) contains supplementary material, which is available to authorized users. * Adriano Fagali de Souza [email protected] 1

about the machine and the manufacturing process, and (iii) connection between CNC and a cloud-based database, allowing monitoring/controlling from other devices (e.g., mobile). Concerning the controller architecture, since the development of CNC machines, the control was manually operated, and the machine was monitored through a dedicated interface. These types of machines are an example of a “closed arc
