Note
If the tool diameter (2x $TC_DP6) is smaller than the upper diameter of the probe
(_TP[i,6]), the tool is always positioned in the center of the probe,
if the tool diameter is larger, the tool is offset by the tool radius toward the center onto the
probe. The value of _ID is subtracted. The axis in which the offset is applied (offset axis)
is also specified in _MA (_MA=103 or MA=203).
If no offset axis is specified (_MA=3), the offset is applied in the abscissa, if necessary,
(for G17: X axis).

Meaning
Measure with motionless spindle, machine-related
Measure with rotating spindle, machine-related
Measure with motionless spindle, workpiece-related
Measure with rotating spindle, workpiece-related
Number of the measuring axis
Measure radius in abscissa direction (milling tool)
Measure radius in ordinate direction (milling tool)
Measure length at center point of the tool probe
(drill or milling tool)
Measure length, offset by radius in abscissa direction (milling tool)
Measure length, offset by radius in ordinate direction (milling tool)
Offset
Parameter is usually set to 0.
With multiple cutters the offset of tool length and the highest point of the
tool edge must be specified in _ID for radius measurement and the offset
from the tool radius to the highest point of the tool edge must be
specified for length measurement.
