Abstract
Abstract This invention relates to a tool presetting gauge for adjusting the cutting edge of a tool fitted in a tool holder externally of a machine tool, or for measuring the position of the cutting edge. It comprises a gauge body with a support side and a bore parallel thereto for fixing the tool holder in a setting plane. The gauge body is provided with two surfaces which are parallel to each other and perpendicular to the support side. The distance between these two surfaces is equal to the distance between the support side and the axis of the bore and the setting plane, respectively. By setting the gauge body with one of the parallel surfaces on a table plate and applying the feeler of a dial gauge onto the other one of the two parallel surfaces the dial gauge can be set to zero. While the dial gauge is held stationary the gauge body is placed with its support side on the table plate, and by means of the feeler of the dial gauge it can be found out whether the tool is in the setting plane or must be adjusted.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
89 words
A gauge for a cutting tool having a cutting edge and carried by a tool holder, said gauge comprising a gauge body; retaining means on said gauge for securing a tool holder to the gauge body; said retaining means locating a tool cutting edge in a predetermined setting plane for such cutting edge; said gauge body having parallel first and second sides and a third side located at a predetermined distance from the setting plane; said predetermined distance being equal to the distance between the first and second sides.
Claim 2
Dependent Claim
89 words
A gauge for a cutting tool having a cutting edge and carried by a tool holder, said gauge comprising a gauge body; retaining means on said gauge for securing a tool holder to the gauge body; said retaining means locating a tool cutting edge in a predetermined setting plane for such cutting edge; said gauge body having parallel first and second sides and a third side located at a predetermined distance from the setting plane; said predetermined distance being equal to the distance between the first and second sides.
Claim 3
Dependent Claim
48 words
A gauge according to claim 1 in which the tool holder is equipped with a shank of circular cross-section, and said gauge includes retaining means in the form of a shank-receiving bore having an axis which extends in the setting plane; said bore receiving the tool holder shank.
Claim 4
Dependent Claim
57 words
A gauge according to claim 2 in which said gauge body comprises at least three planar faces of which two comprise said first and second sides, and said third face comprises said third side which is disposed at right angles to said first and second sides and is arranged parallel to the axis of the shank-receiving bore.
Claim 5
Dependent Claim
61 words
The gauge according to claim 2 in which the periphery of said gauge body joining said first and second sides defines a square and the width of one side of said square is equal to half the length of one side of said square; the axis of the shank-receiving bore being located at the intersection of the diagonals of the square.
Claim 6
Dependent Claim
58 words
A gauge according to claim 4 in which the face of the gauge body on which the tool holder is mounted defines the face of a half cube and has at least one projection extending in the plane of the gauge third side on which the gauge may rest when said gauge is disposed on a supporting surface.
Claim 7
Dependent Claim
56 words
A gauge according to claim 5 in which a projection is provided at each corner of the tool-receiving face of the gauge body; each of said projections comprising at least two mutually perpendicular plane faces; each of the latter faces extending in the plane of one of the mutually perpendicular side faces of the gauge body.
Claim 8
Dependent Claim
42 words
A gauge according to claim 2 in which said gauge includes a clamping means mounted in said gauge body for securing the shank of the tool holder to said gauge when such shank is inserted into the shank-receiving bore of said gauge.
Claim 9
Dependent Claim
38 words
A gauge according to claim 1 in which the width of said gauge third side is equal to the distance between the third side and the setting plane; said third side and setting plane being in parallel relationship.
Claim 10
Dependent Claim
23 words
A gauge according to claim 1 including means on said gauge body for aligning an engaged tool holder relative to the setting plane.
Claim 11
Dependent Claim
29 words
A gauge according to claim 1 in which said gauge includes a measuring apparatus having a support plate defining a planar support surface, and a vertically adjustable distance sensor.
