Abstract

In this new era of manufacturing industries with the Fourth technological revolution (IR 4.0), the smart factory is getting much attention as an answer for the factory of the future. IR 4.0 is about automation and the improvement of technology and advanced devices used by various systems. As a result, the topic of Internet of Things (IoT) based machine monitoring systems has caught the attention of the researcher. The Internet of Things (IoT) can reduce manufacturing costs, improve uptime and help operators gain process insight. Since CNC machining is an important role in manufacturing industries, the demand for smart factory is also increasing. Remote monitoring system is one of the component in building a smart factory. It is important to able to monitor machines efficiently in order to increase operation performance. Most CNC machine is still using the human machine interface or HMI to monitor the machine. This requires machine operator to monitor each machine individually. It can slows down the whole operation and increase the idle time and labour cost. This thesis will be about the design and development of a machine monitoring system by utilizing virtual component-and IoT technologies to monitor the three-axis CNC milling machine. The objective is to able to monitor important parameters of the CNC machine while running such as the cutting tool temperature, voltage, current and the spindle motor's RPM. To achieve these objectives, the system is implemented using a Microcontroller such as an Arduino board and multiple sensors. Compared to the traditional monitoring system like EPL bus, by utilizing the IoT technologies to the monitoring system, the machine condition data can be transmitted and stored wirelessly to computers or smartphones. The industrial monitoring system has grown in popularity in recent years, a industrial owner is looking for ways to monitor their operation line and their industrial values. From these systems, data from multiple machines can be received altogether at once in real-time. These systems also embody a sort of primary unit for enabling the ‘Smart Factory’ revolution.
