The application of IoT technology in CNC machine tool equipment

The Internet of Things (IoT) has experienced explosive growth in recent years, with market revenue projected to hit $1.5 trillion by 2029. IoT refers to a network of physical objects—from smartwatches to industrial machines—embedded with sensors and internet connectivity, enabling them to gather and exchange data.

For instance, a fitness tracker monitors heart rate and syncs the data to a smartphone app, while smart home devices adjust lighting and temperature automatically. Beyond consumer gadgets, IoT plays a crucial role in industrial automation, smart cities, and infrastructure management, optimizing efficiency across industries.

Real-time Data Acquisition and Monitoring

Through deploying various types of sensors on CNC machine tools, such as vibration sensors, temperature sensors, current sensors, etc., IoT technology is able to collect real-time machine tool operation data and transmit it to the cloud or local servers through wireless networks. These data are analyzed and processed to reflect the working status of the machine tool in real time, including machining accuracy, load conditions, fault warning, etc., providing decision support for production managers.

Remote Monitoring and Troubleshooting

Remote monitoring systems based on IoT technology make the maintenance of CNC machine tools no longer limited by geographic location. Technicians can access machine data remotely via a computer or mobile device for real-time monitoring and troubleshooting. Once an abnormality is detected, the system can immediately issue an alarm and automatically or assist the technician to carry out troubleshooting, which greatly reduces downtime and improves production efficiency.

Intelligent Scheduling and Collaborative Operations

In an intelligent manufacturing workshop, multiple CNC machine tools often need to work together to complete complex production tasks.IoT technology realizes information sharing and collaborative control between machine tools by building a workshop-level IoT system. The system is able to automatically allocate machine resources according to production tasks, optimize the machining sequence, reduce waiting time, and improve overall production efficiency. At the same time, it can also make dynamic adjustments according to the actual operating conditions of the machine tools to ensure the smooth operation of the production process.

Construction of Equipment Management System Based on Internet of Things

The construction of a CNC machine tool equipment management system based on the Internet of Things requires a comprehensive design in terms of hardware architecture, software platform and data processing.

Hardware Architecture

First of all, we need to install a variety of sensors on the CNC machine tool, such as: vibration sensor, used to monitor the vibration of the machine tool operation, to prevent abnormal jitter affecting machining accuracy. Temperature sensors, real-time detection of spindle, motor and other critical parts of the temperature, to avoid overheating damage. RFID tags, affixed to the tool, automatic recording of the number of times used and wear and tear, easy to manage.

The data collected by these sensors need to be transmitted to the cloud or local server via industrial communication protocols (e.g. Modbus, OPC UA, MQTT). To reduce the network burden, we will also deploy an edge computing gateway near the machine tool to initially process the data before uploading critical information.

Software Platforms

Data alone is not enough, we have to have a good software system to manage and analyze this information. This platform consists of three main functional modules: Equipment Monitoring Center, Intelligent Operation and Maintenance Module, and Predictive Maintenance.

Real-time data visualization enables you to intuitively see the operating status of each machine. The location of multiple machines is marked on a map, making it easy to quickly locate problematic equipment. Each machine is scored according to its operating data, and below a certain threshold, it is time for overhaul.

Builds a knowledge base of faults and automatically matches similar cases with solutions when problems are encountered. Self-diagnosis can analyze the data to determine whether it is a mechanical failure, electrical problem or program error. After discovering the problem, it generates repair work orders directly and pushes them to the corresponding technicians.

Data Analysis

Use AI algorithms to predict machine or tool life and recommend the best time for maintenance. Automatically calculates which spare parts are needed to avoid temporary stock-outs that delay maintenance.
