Measuring variants
3.3 Measure workpiece (milling)
With the selection Setpoint center point "YES", the position of the rectangular spigot center
can be defined as workpiece zero through setpoint specifications.
Measure: Rectangular spigot (CYCLE977)
Requirements
● The probe must be active as tool.
● Tool type of the probe:
– 3D multi probe (type 710)
– Mono probe (type 712)
– Star-type probe (type 714)
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 must be positioned above the rectangular spigot at the position setpoint of the center
point. This position approached above the spigot represents the starting position and at the
same time the setpoint for the offsets to be determined.
With the infeed path that has been entered, it must be guaranteed that from the starting position
height, the desired measuring height at the rectangular spigot can be reached.
