Machine lubrication systems are a very important portion of manufacturing and production workshop maintenance. Automatic lubrication systems eliminate the need for often careless manual lubrication, providing a safer, more frequent, and opportune monitored approach to machine lubrication. However, traditional automated lubrication systems have inherent environmental and technical-economic problems. With the goal of higher machining precision, cost-effectiveness, greater reduction in oil consumption, and more flexible performance, an automated lubrication control system is introduced in this research work. The new automated lubrication control system in computer numerical control machine tool guideways is a novel approach in machining technology; failure detection/correction in the lubrication system may be identified by temperature signals from sensitive temperature sensors installed in the machine tool guideways, with the signals reflecting the friction, wear, and loading conditions. Data collected via temperature sensors, data analysis, and preparation of commanding signals are analyzed by a lubrication control unit (LCU). The LCU transmits signals to actuators to trigger oil injection by the oil pump. The display unit presents real-time measured temperature variations along with the pump's operation state.
