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 amount of the set-up clearance (value from touch probe table + value from cycle) above the calibration sphere.
With Cycle 460 you can calibrate a triggering 3D touch probe automatically using an exact calibration sphere.
It is also possible to capture 3D calibration data. Option 92, 3D-ToolComp, is required for this purpose. 3D calibration data describe the deflection behavior of the touch probe in any probing direction. The 3D calibration data are stored under TNC:\system\3D-ToolComp\*. The DR2TABLE column of the tool table references the 3DTC table. The 3D calibration data are then taken into account when probing. This 3D calibration is necessary if you want to achieve very high accuracy, for example with Cycle 444 or if you want to graphically align the workpiece (option 159).
Before starting the calibration cycle, you need to pre-position the touch probe:
It must be possible to probe the north pole and south pole during calibration. If this is not possible, the control cannot determine the sphere radius. Ensure that no collision can occur.

The setting in parameter Q433 specifies whether you can perform radius and length calibration, or just radius calibration.
The setting in parameter Q455 specifies whether you can perform an additional 3D calibration
HEIDENHAIN guarantees the proper operation of the touch probe cycles only in conjunction with HEIDENHAIN touch probes.

Q407 Radius of calib. sphere? Enter the exact radius of the calibration sphere being used. Input: 0.0001...99.9999 | |
Q320 Set-up clearance? Additional distance between touch point and ball tip. Q320 is added to SET_UP (touch probe table), and is only active when the preset is probed in the touch probe axis. This value has an incremental effect. Input: 0...99999.9999 or PREDEF | |
Q301 Move to clearance height (0/1)? Specify how the touch probe moves between measuring points: 0: Move at measuring height between measuring points 1: Move at clearance height between measuring points Input: 0, 1 | |
Q423 Number of probes? Number of measuring points on the diameter. This value has an absolute effect. Input: 3...8 | |
Q380 Ref. angle in ref. axis? Enter the reference angle (basic rotation) for acquiring the measuring points in the active workpiece coordinate system. Defining a reference angle can considerably enlarge the measuring range of an axis. This value has an absolute effect. Input: 0...360 | |
Q433 Calibrate length (0/1)? Define whether the control will calibrate the touch probe length after radius calibration: 0: Do not calibrate touch probe length 1: Calibrate touch probe length Input: 0, 1 | |
Q434 Preset for length? Coordinate of the calibration sphere center. This value must be defined only if length calibration will be carried out. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q455 No. of points for 3-D calibrtn.? Enter the number of touch points for 3D calibration. A value of about 15 touch points is useful. If you enter 0, the control will not perform a 3D calibration. During 3D calibration, the deflecting behavior of the touch probe is determined under various angles, and the values are stored in a table. 3D-ToolComp is required for 3D calibration. Input: 0...30 |
NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.
Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.
In addition, test the NC programs using the simulation before the actual program run.
With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.
