SD54621 $SNS_MEA_CAL_EDGE_PLUS_DIR_AX2[n] Calibration slot edge in the positive direc‐
tion of the 2nd measuring axis.
SD54622 $SNS_MEA_CAL_EDGE_MINUS_DIR_AX2[n] Calibration slot edge in the negative di‐
rection of the 2nd measuring axis.
Note
For a standard lathe with axes X and Z (G18), axis Z is the 1st measuring axis and axis X is
the 2nd measuring axis.
21.10.4.5 Measuring tools at the turning machines
Calibration data of the tool probe referred to the machine coordinate system
If you wish to calibrate the tool probe in the machine coordinate system, then the position of
the tool probe in the machine coordinate system must be entered into the following general
cycle setting data.
SD54625 $SNS_MEA_TP_TRIG_MINUS_DIR_AX1[k] Trigger point in minus direction of the
1st measuring axis (for G18 Z).
SD54626 $SNS_MEA_TP_TRIG_PLUS_DIR_AX1[k] Trigger point in plus direction of the
1st measuring axis (for G18 Z).
SD54627 $SNS_MEA_TP_TRIG_MINUS_DIR_AX2[k] Trigger point in minus direction of the
2nd measuring axis (for G18 X).
SD54628 $SNS_MEA_TP_TRIG_PLUS_DIR_AX2[k] Trigger point in plus direction of the
2nd measuring axis (for G18 X).
Calibration data of the tool probe referred to the workpiece coordinate system
If you wish to calibrate the tool probe in the workpiece coordinate system, then the position of
the tool probe in the workpiece coordinate system must be entered into the following general
cycle setting data. In this case, the reference point is the outer diameter or the tool length of
the active tool in the spindle.
Index [k] stands for the number of the actual data field (probe number -1).
SD54640 $SNS_MEA_TPW_TRIG_MINUS_DIR_AX1[k] Trigger point in minus direction of the
1st measuring axis (for G18 Z).
SD54641 $SNS_MEA_TPW_TRIG_PLUS_DIR_AX1[k] Trigger point in plus direction of the
1st measuring axis (for G18 Z).
SD54642 $SNS_MEA_TPW_TRIG_MINUS_DIR_AX2[k] Trigger point in minus direction of the
2nd measuring axis (for G18 X).
SD54643 $SNS_MEA_TPW_TRIG_PLUS_DIR_AX2[k] Trigger point in plus direction of the
2nd measuring axis (for G18 X).
