Standard tool diameter gage
View Patent ↗A device and method used in a spindle or fixture to measure tool sizes. The device has two conical shapes that have precision machined surfaces. The device's face has a precise size which is the same nominal size as that of a material removing tool. The device's shaft allows for concentric and precision fastening of the device to a spindle or a fixture. The nose of the device is located on the end of the larger of the two conical shapes which is visible exposed when mounted and used. The end of the device is at the end of the smaller of the two conical shapes which is hidden after mounting. The combination of using the device and method will allow more accurate programming of machine tools which in turn will provide higher quality results on machined work pieces and reduced machining cycles.
1. A method of aligning a machine cutting tool, said method comprising:
selecting a preferred cutting tool and determining a size of a gage;
mounting said gage in a machine tool spindle;
traversing said gage to a test indicator;
loading said indicator on a dial on a highest peak of a standard tool diameter gage;
traversing said gage repeatedly across the indicator verifying reach of this highest point of contact;
rotating the spindle to ensure an absence of run out;
adjusting the indicator to a common value shown on the dial; and,
retracting the machine spindle from the indicator.
2. The method of measuring a cutting tool of claim 1 further comprising:
said loading said indicator including setting an indicator with a gage.
3. The method of measuring a cutting tool in claim 1 wherein said traversing the gage over an indicator includes transferring a measurement.
4. The method of measuring a cutting tool in claim 1 further comprising:
positioning an indicator to a “set”; and, measuring the cutting tool from the “set” indicator reading.
