19.3 Calibrate the wireless TT 449 (Cycle
484, DIN/ISO: G484 Touch Probe
Functions)
Fundamentals
With Cycle 484, you can calibrate your tool touch probe, e.g the
wireless infrared TT 449 tool touch probe. The calibration process
is either fully automatic or semi-automatic, depending on the
parameter setting.
Semi-automatic —stop before running: A dialog asks you to
manually move the tool over the TT
Fully automatic —no stop before running: Before using Cycle
484 you must move the tool over the TT
Cycle run
To calibrate the tool touch probe, program the measuring cycle TCH
PROBE 484. In the input parameter Q536, you can specify whether
you want to run the cycle semi-automatically or fully automatically.
Semi-automatic—stop before running
Insert the calibrating tool
Define and start the calibration cycle
The TNC interrupts the calibration cycle
The TNC opens a dialog in a new window
The dialog asks you to manually position the calibrating tool
above the center of the touch probe. Ensure that the calibrating
tool is located above the measuring surface of the probe contact
Fully automatic—no stop before running
Insert the calibrating tool
Position the calibrating tool above the center of the touch probe.
Ensure that the calibrating tool is located above the measuring
surface of the probe contact
Define and start the calibration cycle
The calibration cycle is executed without stopping. The
calibration process starts from the current position of the tool.
Calibrating tool:
The calibrating tool must be a precisely cylindrical part, for example
a cylinder pin. Enter the exact length and radius of the calibrating
tool into the tool table TOOL.T. At the end of the calibration
process, the TNC stores the calibration values and takes them into
account during subsequent tool measurement. The calibrating tool
should have a diameter of more than 15 mm and protrude approx.
50 mm from the chuck.
