Measuring variants
3.3 Measure workpiece (milling)
Preconditions
● The probe must be active as tool.
● Tool type of the probe:
– 3D multi probe (type 710)
– Mono probe (type 712)
– L probe (type 713)
– Star-type probe (type 714)
When using the measuring version on lathes:
● Use probe type 710 or 580
● Set the length reference of the workpiece probe to the center of the probe ball:
MD51740 $MNS_MEA_FUNCTION_MASK, bit 1 = 0
Note
The following measuring methods are only possible in the axes of the plane:
● 3D probe with spindle reversal (differential measurement)
● Align 3D probe
The probe types 712, 713 and 714 generally cannot be used for these measuring methods.
Starting position before the measurement
The probe should be positioned at a distance that is somewhat greater than the measurement
path (DFA) with respect to the surface to be measured.
Position after the end of the measuring cycle
After the measurement has been completed, the probe ball with its circumference is at a
distance of the measuring path DFA with respect to the measuring surface.

Note
L probe application (type 713)
Measurement in +Z (for towing measurement) is possible with the L probe.
The basic alignment of the L probe boom is toward +X (offset angle = 0). If the probe
boom is to be aligned in a different direction in the measuring program, this can
performed through a rotation around the tool axis (e.g. ROT Z = 90).
