Cycle parameters
U Mode (0=Check/1=Measure) Q406: Specify whether
the TNC should check or optimize the active
kinematics:
0: Check the active machine kinematics. The TNC
measures the kinematics in the 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 the active machine kinematics. The TNC
measures the kinematics in the rotary axes you have
defined and optimizes the position of the rotary
axes of the active kinematics.
2: Optimize the active machine kinematics. The TNC
measures the kinematics in the rotary axes you have
defined and optimizes the position and
compensates the angle of the rotary axes of the
active kinematics. The KinematicsComp option must
be enabled for Mode 2.
U Exact calibration sphere radius Q407: Enter the
exact radius of the calibration sphere used. Input
range 0.0001 to 99.9999
U Setup clearance Q320 (incremental): Additional
distance between measuring point and ball tip. Q320
is added to MP6140. Input range 0 to 99999.9999,
alternatively PREDEF
U Retraction height Q408 (absolute): Input range
0.0001 to 99999.9999
„ Input 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 series
A, then B, then C.
„ Input >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 probe monitoring
is not active in this mode. Define the positioning
velocity in parameter Q253.
