19.3 Calibrating the wireless TT 449 (Cycle
484, DIN/ISO: G484, software option
17)
Fundamentals
With Cycle 484, you calibrate the wireless infrared TT 449 tool
touch probe. The calibration process is not completely automated,
because the TT's position on the table is not defined.
Cycle run
Insert the calibrating tool
Define and start the calibration cycle
Position the calibrating tool manually above the center of the
touch probe and follow the instructions in the pop-up window.
Ensure that the calibrating tool is located above the measuring
surface of the probe contact
The calibration process is semi-automatic. The TNC also measures
the center misalignment of the calibrating tool by rotating the
spindle by 180° after the first half of the calibration cycle.
The calibrating tool must be a precisely cylindrical part, for example
a cylinder pin. The resulting calibration values are stored in the
TNC memory and are accounted for during subsequent tool
measurement.
The calibration tool should have a diameter of more
than 15 mm and protrude approx. 50 mm from the
chuck. This configuration causes a deformation of 0.1
µm per 1 N of probing force.
Please note while programming:
The functioning of the calibration cycle is dependent
on machine parameter
CfgToolMeasurement. Refer
to your machine manual.
Before calibrating the touch probe, you must enter
the exact length and radius of the calibrating tool into
the tool table TOOL.T.
The TT needs to be recalibrated if you change its
position on the table.
Cycle parameters
Cycle 484 has no cycle parameters.
