Set the measurement point in parameter #2015 tlml– beforehand.
Measurement point
Z-axis + tlml

Always set the measurement
point with the radius,
regardless of the diameter/
radius command.
Set the measurement point in
the machine coordinate
system.
Tool length = Machine value - Measurement point (tlml)
The expression above is used for automatic calculation in the basic point method. When the tool nose
is placed on the measuring point, the distance from the tool nose to the tool length basic point is
calculated.
