Calibrating The Wireless - HEIDENHAIN ITNC 530 - CYCLE PROGRAMMING User Manual

19.3 CALIBRATING THE WIRELESS

TT 449 (Cycle 484, DIN/ISO:
G484)
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
U
Insert the calibrating tool.
U Define and start the calibration cycle.
U 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
constellation causes a deformation of 0.1 µm per 1 N
probing force.
Please note while programming:
The functioning of the calibration cycle is dependent on
MP 6500. 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.
