Abstract
Abstract A displacement transducer is manually applied to the cutting surface of a diamond wheel to measure the fixed reference distance and thus degree of wheel wear. The output of the transducer is amplified and directed to visual or print out devices, and archival systems. The transducer signal may be transmitted to provide central processing of field measurements.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
136 words
A system for measuring blade wear comprising: a displacement transducer having a follower, said transducer being adapted and arranged to generate a signal output in response to displacement of the follower; fixture means for mounting said transducer in fixed relative position thereon, said fixture means having fixedly positioned reference means for engaging said blade on a predetermined location such that said follower contacts the wear surface of the blade; processing means operatively coupled to said transducer means to derive a signal input therefrom and amplify and calibrate said signal and said processing means also including means for storing reference datum and means for subtracting said reference datum from the data measued by the transducer to provide a net blade wear output signal; and means coupled to said processing means for outputting the net blade wear signal.
Claim 2
Independent Claim
136 words
A system for measuring blade wear comprising: a displacement transducer having a follower, said transducer being adapted and arranged to generate a signal output in response to displacement of the follower; fixture means for mounting said transducer in fixed relative position thereon, said fixture means having fixedly positioned reference means for engaging said blade on a predetermined location such that said follower contacts the wear surface of the blade; processing means operatively coupled to said transducer means to derive a signal input therefrom and amplify and calibrate said signal and said processing means also including means for storing reference datum and means for subtracting said reference datum from the data measued by the transducer to provide a net blade wear output signal; and means coupled to said processing means for outputting the net blade wear signal.
Claim 3
Dependent Claim
40 words
The system of claim 1, wherein said processing means includes means adjacent said transducer for transmitting said transducer signal, and receiver means, remote from transducer, for receiving said signal, whereby remotely measured, centrally processed blade wear intelligence may be gathered.
Claim 4
Dependent Claim
13 words
The system of claim 1, wherein said output means includes a visual readout.
Claim 5
Dependent Claim
12 words
The system of claim 1, wherein said output means includes a printer.
