17.2 CALIBRATE TS (Cycle 2)
Cycle run
Touch probe cycle 2 automatically calibrates a touch trigger probe
using a ring gauge or a precision stud as calibration standard.
1
The touch probe moves at rapid traverse (value from MP6150) to
the clearance height (but only if the current position is below the
clearance height).
2 Then the TNC positions the touch probe in the working plane to the
center of the ring gauge (calibration from inside) or in its proximity
(calibration from outside).
3 The touch probe then moves to the measuring depth (result of
MP618x.2 and MP6185.x) and probes the ring gauge successively
in X+, Y+, X- and Y-.
4 Finally, the TNC moves the touch probe to the clearance height
and writes the effective radius of the ball tip to the calibration data.
Please note while programming:
Cycle parameters
 Clearance height (absolute): Coordinate in the touch
probe axis at which the touch probe cannot collide
with the calibration workpiece or any fixtures. Input
range -99999.9999 to 99999.9999
 Radius of ring gauge: Radius of the calibrating
workpiece. Input range 0 to 99999.9999
 Inside calib. =0/outs. calib.=1:
Definition of
whether the TNC is to calibrate from inside or outside:
0: Calibrate from inside
1: Calibrate from outside
Before you begin calibrating, you must define in Machine
Parameters 6180.0 to 6180.2 the center of the calibrating
workpiece in the working space of the machine (REF
coordinates).
If you are working with several traverse ranges you can
save a separate set of coordinates for the center of each
calibrating workpiece (MP6181.1 to 6181.2 and MP6182.1
to 6182.2).
