Rotary axes
If your machine has rotary axes, you can include these rotary axes in the measurement and
setup procedure. If you store the workpiece zero in a work offset, rotary axis positioning may
be necessary in the following cases.
● Correcting the work offset requires you to position the rotary axes to align the workpiece
parallel with the coordinate system, e.g. with "Align edge".
● Correcting the work offset rotates the workpiece coordinate system, which should align the
tool perpendicular to the plane, e.g. for "Align plane".
You are supported by one or two activation windows when you position the rotary axes (see
"Corrections after measuring the zero point (Page 137)").
You can only select "Rotary axis <name of rotary axis>" for the "Angle corr." parameter if your
machine has rotary axes.
They must also be assigned to geometry axes via the machine data.

4.6.2 Sequence of operations
To measure the workpiece zero, the workpiece probe must always be located or set
perpendicular to the measuring plane (machining plane) (e.g. using "Align plane").
For the measuring versions "Set edge", "Distance 2 edges", "Rectangular pocket" and
"Rectangular spigot", the workpiece must first be aligned parallel to the coordinate system.
To do this, it may be necessary to perform the measuring process in several steps.
Possible step sequences
1. "Align plane" (to align the workpiece probe perpendicular to the plane)
2. "Align edge" (to align the workpiece parallel to the coordinate system)
3. "Set edge" or "Distance 2 edges" of "Rectangular pocket" or
"Rectangular spigot", to define the workpiece zero.
- OR -
1. "Align plane" (to align the workpiece probe perpendicular to the plane)
2. "Corner" or "2 holes" or "2 spigots", to align the the coordinate system parallel to the
workpiece and to determine the workpiece zero)
