Touch Probe Cycles: Special Functions | CALIBRATE TS (Cycle 460, DIN/ISO: G460)
Radius and length calibration Q433=1
1 Clamp the calibration sphere. Ensure the prevention of collisions
2 In the touch probe axis, position the touch probe over the
calibration sphere, and in the working plane, approximately over
the sphere center.
3 The TNC first moves in the plane, depending on the reference
angle (Q380).
4 The TNC then positions the touch probe in touch-probe axis.
5 The probing process starts, and the TNC begins by searching for
the equator of the calibration sphere
6 Once the equator has been determined, the radius calibration
begins
7 Then the TNC returns the touch probe in the touch-probe axis to
the height at which it had been pre-positioned.
8 The TNC ascertains the length of the touch probe at the north
pole of the calibration sphere
9 At the end of the cycle the TNC returns the touch probe in
the touch-probe axis to the height at which it had been pre-
positioned.
The setting in parameter Q455 specifies whether you can perform
an additional 3-D calibration.
3-D calibration Q455= 1...30
1 Clamp the calibration sphere. Ensure the prevention of collisions
2 After calibration of the radius or length, the TNC retracts the
touch probe in touch-probe axis. Then the TNC positions the
touch probe over the north pole
3 The probing process goes from the north pole to the equator in
several steps. Deviations from the nominal value, and therefore
the specific deflection behavior, are thus determined
4 You can specify the number of probing points between
the north pole and the equator. This number depends on
input parameter Q455. A value between 1 and 30 can be
programmed. If you program Q455=0, no 3-D calibration will be
performed.
5 The deviations determined during the calibration are stored in a
3DTC table.
6 At the end of the cycle the TNC returns the touch probe in
the touch-probe axis to the height at which it had been pre-
positioned.
