Touch Probe Cycles: Automatic Kinematics Measurement | MEASURE KINEMATICS (Cycle 451, DIN/ISO:
G451, option)

Cycle parameters

Q406 Mode (0/1/2): Specify whether the TNC
should check or optimize the active kinematics:
0: Check active machine kinematics. The TNC
measures the kinematics in the rotary axes you
have defined, but it does not make any changes to
it. The TNC displays the results of measurement in
a measurement log.
1: Optimize active machine kinematics: The TNC
measures the kinematics in the rotary axes you
have defined. It then optimizes
the rotary axes
2: Optimize active machine kinematics: The
TNC measures the kinematics in the rotary
axes you have defined. It then optimizes
and positioning errors.
KinematicsComp is required for compensation of
angle errors.
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
Q253 Feed rate for pre-positioning? Enter the
traversing speed of the tool in mm/min during
positioning. Input range 0.0001 to 99999.9999;
alternatively FMAX, FAUTO, PREDEF
