Please note while programming:
HEIDENHAIN only warrants the function of the touch
probe cycles if HEIDENHAIN touch probes are used.
Before a cycle definition you must have programmed
a tool call to define the touch probe axis.
The center offset can be determined only with a
suitable touch probe.
A measuring log is created automatically during
calibration. The log file is named TCHPRAUTO.html.
In order to be able to determine the ball-tip center
misalignment, the TNC needs to be specially
prepared by the machine manufacturer. The machine
manual provides further information.
The characteristic of whether and how your
touch probe can be oriented is already defined in
HEIDENHAIN touch probes. Other touch probes are
configured by the machine tool builder.
RING RADIUS Q407: Diameter of the ring gauge.
Input range 0 to 99.9999
SET-UP CLEARANCE Q320 (incremental): Additional
distance between measuring point and ball tip.
Q320 is added to SET_UP (touch probe table). Input
range 0 to 99999.9999
NO. OF PROBE POINTS Q407 (absolute): Number of
measuring points on the diameter. Input range 0 to
8
REFERENCE ANGLE Q380 (absolute): Angle
between the reference axis of the working plane
and the first touch point. Input range 0 to 360.0000
