Abstract
Abstract A honing or grinding tool and a measuring device used therewith is descri The honing tool includes a cutting element, a cutting element support and a layer disposed between and connecting the cutting element and the cutting element support. The layer includes a substance embedded therein which selectively absorbs and/or emits electromagnetic radiation at specific wavelengths, such that the substance is exposed when the cutting element is worn off and detected by the measuring device.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
103 words
A cylindrical honing or grinding tool, comprising: at least one cutting element having an extent in the circumferential direction of the tool; a steel base cutting element support for each cutting element; and an adhesive layer disposed between and connecting each cutting element and its respective cutting element support, each said adhesive layer having a fluorescing substance embedded therein which selectively absorbs and/or emits electromagnetic radiation at specific wavelengths, such that the fluorescing substance is exposed when the cutting element is worn off, said fluorescing substance after being excited by a first set wavelength distribution emitting radiation of a second set wavelength distribution.
Claim 2
Dependent Claim
103 words
A cylindrical honing or grinding tool, comprising: at least one cutting element having an extent in the circumferential direction of the tool; a steel base cutting element support for each cutting element; and an adhesive layer disposed between and connecting each cutting element and its respective cutting element support, each said adhesive layer having a fluorescing substance embedded therein which selectively absorbs and/or emits electromagnetic radiation at specific wavelengths, such that the fluorescing substance is exposed when the cutting element is worn off, said fluorescing substance after being excited by a first set wavelength distribution emitting radiation of a second set wavelength distribution.
Claim 3
Dependent Claim
17 words
The honing or grinding tool as defined in claim 1, wherein said fluorescing substance absorbs UV radiation.
Claim 4
Dependent Claim
17 words
The honing or grinding tool as defined in claim 1, wherein said fluorescing substance absorbs infrared radiation.
Claim 5
Dependent Claim
67 words
A honing or grinding tool, comprising: a cutting element; a cutting element support; and a layer disposed between and connecting the cutting element and the cutting element support, said layer having a recess formed therein within which an indicator carrier surrounded by a further layer is embedded, said further layer having fluorescing substance therein, such that the substance is exposed when the cutting element is worn off.
Claim 6
Dependent Claim
67 words
A honing or grinding tool, comprising: a cutting element; a cutting element support; and a layer disposed between and connecting the cutting element and the cutting element support, said layer having a recess formed therein within which an indicator carrier surrounded by a further layer is embedded, said further layer having fluorescing substance therein, such that the substance is exposed when the cutting element is worn off.
Claim 7
Dependent Claim
17 words
The honing or grinding tool as defined in claim 4, wherein the indicator carrier comprises a wire.
Claim 8
Dependent Claim
17 words
The honing or grinding tool as defined in claim 5, wherein the wire is of non-ferrous metal.
Claim 9
Dependent Claim
29 words
The honing or grinding tool as defined in claim 4, wherein the recess comprises a groove which extends into said cutting element, said cutting element support and said layer.
Claim 10
Dependent Claim
43 words
The honing or grinding tool as defined in claim 4, wherein the cutting element comprises a cutting layer, the cutting element support comprises a steel base, and the layer disposed between the cutting element and the cutting element support comprises an adhesive layer.
Claim 11
Dependent Claim
30 words
The honing or grinding tool as defined in claim 4, wherein said substance, after being excited by a first set wavelength distribution, emits radiation of a second set wavelength distribution.
Claim 12
Dependent Claim
21 words
The honing or grinding tool as defined in claim 4, wherein said fluorescing substance comprises a substance which absorbs UV radiation.
Claim 13
Dependent Claim
21 words
The honing or grinding tool as defined in claim 4, wherein said fluorescing substance comprises a substance which absorbs infrared radiation.
