Refer to your machine manual.

Before starting the calibration cycle, you need to pre-position the touch probe above the center of the calibration sphere. Position the touch probe in the touch probe axis by approximately the set-up clearance (value from touch probe table + value from cycle) above the calibration sphere.
With Cycle 460 you can calibrate a triggering 3‑D touch probe automatically using an exact calibration sphere.
It is also possible to capture 3‑D calibration data. Option 92, 3D-ToolComp, is required for this purpose. 3-D calibration data describe the deflection behavior of the touch probe in any probing direction. The 3-D calibration data are stored under TNC:\system\3D-ToolComp\*. The DR2TABLE column of the tool table references the 3DTC table. The 3-D calibration data are then taken into account when probing. This 3‑D calibration is necessary if you want to achieve a very high accuracy with Cycle 444 3‑D Probing (see Cycle 444 PROBING IN 3-D ).
