Abstract
A bonded abrasive wheel is disclosed comprising a plurality of abrasive particles disposed in a binder, a first grinding surface, a second surface opposing the first grinding surface, and an outer circumference. The wheel comprises a rotational axis extending through a central hub and a circuit configured as a Radio Frequency Identification (RFID) unit coupled to the abrasive wheel. The circuit comprises an antenna configured to communicate with one or more external devices and comprising a first end and a second end, wherein antenna has a radius of curvature about an axis along at least a portion thereof such that the first end is disposed adjacent to but is spaced from the second end, and an integrated circuit (IC) operably coupled to the antenna and configured to store at least a first data.
