21.10 Measuring cycles and measurement functions
Decimal place
Example
If the general cycle machine data SD54647 $SNS_MEA_TPW_AX_DIR_AUTO_CAL has the
value 123, the tool probe is calibrated as follows in the G17 plane:
● X in both directions
● Y only in plus direction
● Z only in minus direction
Monitoring when measuring with a rotating spindle
SD54670 $SNS_MEA_CM_MAX_PERI_SPEED[0]
= 100
SD54671 $SNS_MEA_CM_MAX_REVOLUTIONS[0]
= 1000
SD54672 $SNS_MEA_CM_MAX_FEEDRATE[0]
= 20
SD54673 $SNS_MEA_CM_MIN_FEEDRATE[0]
= 1
SD54674 $SNS_MEA_CM_SPIND_ROT_DIR[0]
4 = M4
Note
If the spindle is already rotating when the measuring cycle is called, this direction of rotation
remains independent of the setting of this data.

Maximum permissible peripheral
speed of the tool to be measured.
Maximum permissible tool speed of the
tool to be measured. The speed is au‐
tomatically reduced when exceeded.
Maximum permissible feedrate to
probe the tool to be measured at the
probe.
Minimum feedrate for the first probing
of the tool to be measured at the probe.
This avoids excessively small fee‐
drates for large tool radii.
Spindle direction of rotation to measure
tools.
