Design and Development of Environmental Protection System Based on CNC Machine

The Computer Numerical Control (CNC) machine may produce a lot of suspended particles in the working environment that have seriously harmed human health, when working. These suspended particles include particulate matter (PM2.5), suspended particulate matter (PM10), and total volatile organic compound (TVOC). Therefore, to improve the working environment, we adopt the Internet of Things (IoT) technology to CNC machines in this study. The indoor air quality sensors connected to the industrial personal computer (IPC) of a CNC machine are used to detect the concentration of suspended particles. Furthermore, in the CNC machine, we also build a humanized interface to analyze the changes of concentration in the time period, and automatically start other devices to reduce it when detecting the high concentration.
