Grinding wheels are normally monitored by complex and costly equipment like acoustic emission sensors and grinding cycle monitors. In the present work, an attempt is made to utilize simple instruments like lux meter for condition monitoring of grinding wheels. As grinding progresses, the metal particles get clogged into the spaces between the abrasive cutting edges of the grinding wheel. This changes the reflectivity of the grinding wheel surface. This change can be captured by using a lux meter. The paper demonstrates the usage of simple lux meter for condition monitoring of grinding wheels.
