Touch Probe Cycles: Automatic Kinematics Measurement | KINEMATICS GRID (Cycle 453, DIN/ISO: G453,
Cycle parameters
Q406 Modus (-1/0/+1): Define whether the
TNC writes the values of the compensation
table (*.kco) with 0, checks the currently existing
deviations or compensates. A protocol (*.html) is
created.
-1: Delete values in the compensation table
(*.kco). The compensation values of TCP
positioning errors are set to 0 in the compensation
table (*.kco). No measuring positions are probed.
No results are output in the protocol (*.html).
0: Check TCP positioning errors. The TNC
measures the TCP positioning errors in accordance
with the rotary axis positions but does not enter
values in the compensation table (*.kco). The TNC
displays the standard and maximum deviation in a
protocol (*.html).
1: Compensate TCP positioning errors. The TNC
measures the TCP positioning errors in accordance
with the rotary axis positions and writes the
deviations to the compensation table (*.kco). The
compensations are then immediately effective.
The TNC displays the standard and maximum
deviation in a protocol (*.html).
Q407 Radius of calib. sphere? Enter the exact
radius of the calibration sphere used. Input range
0.0001 to 99.9999
Q320 Set-up clearance? (incremental): Define
an additional distance between measuring
point and ball tip. Q320 is added to SET_UP
in the touch probe table. Input range 0 to
99999.9999Alternatively PREDEF
Q408 Retraction height? (absolute) Input range
0.0001 to 99999.9999
0: Do not move to any retraction height. The TNC
moves to the next measuring position in the axis
to be measured. Not allowed for Hirth axes! The
TNC moves to the first measuring position in the
sequence A, then B, then C
>0: Retraction height in the untilted workpiece
coordinate system to which the TNC positions
before a rotary axis positioning in the spindle
axis. Also, the TNC moves the touch probe in
the working plane to the datum. The touch probe
monitor is not active in this mode. Define the
positioning speed in parameter Q253
