Abstract
A grinding wheel system includes a grinding wheel with at least one embedded sensor. The system also includes an adapter disk containing electronics that process signals produced by each embedded sensor and that transmits sensor information to a data processing platform for further processing of the transmitted information.
Claims18
A grinding wheel system, comprising:
- a grinding wheel including at least one embedded sensor, each sensor having a lead;
- an adapter disk containing electronics that process signals produced by each embedded sensor, the adapter disk constructed to attach to the grinding wheel and connect to each sensor lead, the electronics including a transmitter that transmits sensor information;
- and
- a data processing platform comprising:
- a processor;
- a receiver that receives sensor information transmitted by the adapter disk electronics;
- and
- instructions that cause the processor to process the received sensor information.

A grinding wheel system, comprising:
- a grinding wheel including at least one piezoceramic sensor embedded near the wheel periphery that detects wheel forces and at least three piezoceramic sensors positioned near the grinding wheel rim that detect acoustic emissions, each sensor having a lead;
- an adapter disk containing electronics that process signals produced by the sensors, the adapter disk constructed to attach to the grinding wheel and connect to each sensor lead, the electronics comprising:
- a multiplexer fed by the sensor leads;
- an analog to digital converter fed by the multiplexer;
- a digital signal processor fed by the analog to digital converter;
- and
- a radio frequency transmitter fed by the digital signal processor that transmits sensor information;
- and
- a data processing platform comprising:
- a processor;
- a radio frequency receiver that receives sensor information transmitted by the adapter disk electronics;
- and
- instructions that cause the processor to process the received sensor information.
