Abstract
Abstract During the dressing of a rotatable grinding disc or wheel, a feeler, which is connected to the dressing tool holder, senses the vibrations of the holder, and transforms them into electrical signals, the potential of which is proportional to the depth to which the tool penetrates the surface of the disc. These signals are used to control the cutting depth of the dressing tool, when necessary; and they may be used to effect repetition of the dressing until a signal of predetermined potential is attained.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
105 words
A method of sharpening the grinding disc in a grinding machine by means of a dressing tool supported by a holder and preferably containing a diamond tip, said tool and said grinding disc prior to each grinding operation being reset in relationship to one another to a position in which a removal of disc material will take place, comprising sensing the amplitude of the vibration of the holder created by the dressing operation, causing the amplitude of the vibrations to produce a potential, which is dependent on the magnitude of the dressing depth, and applying the potential to a meter for reading the dressing depth.
Claim 2
Independent Claim
105 words
A method of sharpening the grinding disc in a grinding machine by means of a dressing tool supported by a holder and preferably containing a diamond tip, said tool and said grinding disc prior to each grinding operation being reset in relationship to one another to a position in which a removal of disc material will take place, comprising sensing the amplitude of the vibration of the holder created by the dressing operation, causing the amplitude of the vibrations to produce a potential, which is dependent on the magnitude of the dressing depth, and applying the potential to a meter for reading the dressing depth.
Claim 3
Independent Claim
101 words
A method of dressing the grinding disc in a grinding machine by means of a dressing tool supported by a holder and preferably containing a diamond tip, said tool and said grinding disc prior to each grinding operation being reset in relationship to one another to a position in which a removal of disc material will take place, comprising detecting, by means of a feeling member, the amplitude of the vibration of the holder created by the dressing operation, producing a potential which is dependent on the magnitude of the dressing depth, and adjusting the dressing depth to a desired value.
Claim 4
Independent Claim
101 words
A method of dressing the grinding disc in a grinding machine by means of a dressing tool supported by a holder and preferably containing a diamond tip, said tool and said grinding disc prior to each grinding operation being reset in relationship to one another to a position in which a removal of disc material will take place, comprising detecting, by means of a feeling member, the amplitude of the vibration of the holder created by the dressing operation, producing a potential which is dependent on the magnitude of the dressing depth, and adjusting the dressing depth to a desired value.
Claim 5
Dependent Claim
22 words
A method as defined in claim 2, including repeating the dressing operation until the magnitude of said potential reaches a predetermined value.
Claim 6
Dependent Claim
27 words
A method as claimed in claim 2, including repeating the dressing operation when the potential developed during a given dressing operation falls below a predetermined minimum value.
Claim 7
Independent Claim
141 words
A method of dressing the grinding disc in a grinding machine by means of a dressing tool supported by a holder in which said tool and said grinding disc prior to each grinding operation are reset in relation to one another to a position in which removal of disc material will take place through a dressing operation, comprising adjusting the dressing depth to a relatively small value, which is normally sufficient to restore the grinding ability of the disc, detecting, by means of a feeling member, the amplitude of the vibration of the holder created in the dressing operation by the mechanical resistance of the grinding disc to movement of the tool across the disc, producing a potential, which is dependent on the vibration of the holder, and, if necessary, repeating the dressing operation until the potential reaches a predetermined value.
Claim 8
Independent Claim
141 words
A method of dressing the grinding disc in a grinding machine by means of a dressing tool supported by a holder in which said tool and said grinding disc prior to each grinding operation are reset in relation to one another to a position in which removal of disc material will take place through a dressing operation, comprising adjusting the dressing depth to a relatively small value, which is normally sufficient to restore the grinding ability of the disc, detecting, by means of a feeling member, the amplitude of the vibration of the holder created in the dressing operation by the mechanical resistance of the grinding disc to movement of the tool across the disc, producing a potential, which is dependent on the vibration of the holder, and, if necessary, repeating the dressing operation until the potential reaches a predetermined value.
