These cycles can determine rotations. They contain the following:
- Consideration of active machine kinematics
- Semi-automatic probing
- Monitoring of tolerances
- Consideration of 3D calibration
- Simultaneous measurement of rotation and position
- Programming and operating notes:
- The probing positions are referenced to the programmed nominal coordinates in the I-CS.
- See the drawing for these nominal positions.
- Before a cycle definition you must program a tool call to define the touch-probe axis.
- The 14xx probing cycles support the SIMPLE and L-TYPE styli.
- In order to achieve optimal accuracy results with an L-TYPE stylus, HEIDENHAIN recommends that you perform probing and calibration at the same speed. Note the setting of the feed override if it is active during probing.

Evaluation – preset:
- If you want to probe objects in a consistent machining plane or probe objects while TCPM is active, you can program any required shifts as basic transformations in the preset table.
- Rotations can be written to the basic transformations of the preset table as basic rotations or as axial offsets from the first rotary table axis, seen from the workpiece.
- Operating notes:
- When probing, existing 3D calibration data are taken into account. If these calibration data do not exist, deviations might be the result.
- If you wish to use not only the rotation but also a measured position, then probe as perpendicularly to the surface as possible. The larger the angular error and the larger the ball-tip radius, the larger the positioning error. If the angular errors in the initial angular position are too large, corresponding position errors might be the result.
Logging:
The measured results are recorded in the TCHPRAUTO.html file and stored in the Q parameters programmed for this cycle.
The measured deviations are the differences between the measured actual values and the mean tolerance value. If no tolerance has been specified, they refer to the nominal dimension.
The unit of measurement of the main program can be seen in the header of the log.
