Abstract

Such excessive cutting temperature in external grinding has a detrimental effect on the surface finish, dimensional accuracy, and overall productivity in the manufacture of bearing components. This manuscript describes the design and industrial application of a real-time Internet of Things-enabled cutting temperature monitoring system developed for the use of cutting SAE 52100 bearing races in an external grinding machine. The system architecture has been integrated with a non-contact infrared temperature sensor, ESP32 microcontroller, wireless communications protocols, cloud-based data storage, and a web-based dashboard with utter threshold alerts to allow for in-process monitoring in a continuous fashion, proximal to the zone of grinding. Industrial additional validation was performed on a series of 259 bearing races at several production shifts. Revealed by empirical data was that there were stable grinding conditions maintained within a temperature band of 21.10°C to 24.95°C, and the highest recorded temperature was obtained at 26.31°C with resulting overall temperature variation of 4.58°C. Sustained presence of cutting temperature in the 20 - 25°C range invariably showed superior surface finish from 0.15 μm to 0.18 μm and dimensional accuracy with ± 0.01mm. To evaluate shift-wise process stability, the Thermal Stability Index (TSI) was introduced. The results validate the idea that the proposed system is a cost-effective, scalable, and industry-ready solution for real-time, quality-oriented monitoring of the grinding process and a basis for future predictive and adaptive control system applications.
