Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
139 words
A device for pre-gauging cutting tools to ascertain their offsets in two directions relative to a master cutting tool comprising: means for releasably holding a cutting tool to be gauged; sensing means for determining whether a cutting tool is present, clamped, or unclamped in the cutting tool clamping means; means for reading an identification code on the cutting tool while the tool is in the cutting tool clamping means; electronic gauging means movable to the gauging position for measuring the offsets between the master tool and the cutting tool; means for advancing and retracting the electronic gauging means from a first home position to a gauging position along a first axis; and means for advancing and retracting said electronic gauging means from a second home position to a gauging position along a second axis perpendicular to the first axis.
Claim 2
Independent Claim
139 words
A device for pre-gauging cutting tools to ascertain their offsets in two directions relative to a master cutting tool comprising: means for releasably holding a cutting tool to be gauged; sensing means for determining whether a cutting tool is present, clamped, or unclamped in the cutting tool clamping means; means for reading an identification code on the cutting tool while the tool is in the cutting tool clamping means; electronic gauging means movable to the gauging position for measuring the offsets between the master tool and the cutting tool; means for advancing and retracting the electronic gauging means from a first home position to a gauging position along a first axis; and means for advancing and retracting said electronic gauging means from a second home position to a gauging position along a second axis perpendicular to the first axis.
Claim 3
Dependent Claim
24 words
The device of claim 1 further including a sensing mechanism for measuring the distance of travel of the electronic gauging means along both axes.
Claim 4
Dependent Claim
23 words
The device of claim 1 wherein the releasably clamping means includes a ball detent clamp-unclamped mechanism operated by a pneumatic cylinder and rod.
Claim 5
Dependent Claim
35 words
The device of claim 3 wherein the tool clamp sensing means includes an actuator sensor attached to the cylinder rod that will align with a plurality of proximity sensors spaced axially along the cylinder rod.
Claim 6
Independent Claim
69 words
A device for pre-gauging cutting tools to ascertain their offsets relative to a master tool, comprising: means for releasably clamping a cutting tool to be gauged; means for reading an identification code on the cutting tool while the tool is in the cutting tool clamping means; and electronic gauging means movable to a gauging position for measuring and providing the offsets between the master tool and the cutting tool.
Claim 7
Independent Claim
69 words
A device for pre-gauging cutting tools to ascertain their offsets relative to a master tool, comprising: means for releasably clamping a cutting tool to be gauged; means for reading an identification code on the cutting tool while the tool is in the cutting tool clamping means; and electronic gauging means movable to a gauging position for measuring and providing the offsets between the master tool and the cutting tool.
Claim 8
Independent Claim
80 words
A method for pre-gauging cutting tools with electronic gauging means to ascertain their offsets relative to a master tool, comprising: releasably holding a cutting tool to be gauged; reading a cutting tool identification code on the cutting tool while the tool is in the cutting tool gauging position; moving the electronic gauging means into engagement with the cutting tool in the gauging position; and measuring with the electronic gauging means any offsets between the master tool and the cutting tool.
Claim 9
Independent Claim
80 words
A method for pre-gauging cutting tools with electronic gauging means to ascertain their offsets relative to a master tool, comprising: releasably holding a cutting tool to be gauged; reading a cutting tool identification code on the cutting tool while the tool is in the cutting tool gauging position; moving the electronic gauging means into engagement with the cutting tool in the gauging position; and measuring with the electronic gauging means any offsets between the master tool and the cutting tool.
