2.6 Measuring the workpiece zero
Zero point
The measurement values for the offsets are stored in the coarse offset and the relevant fine
offsets are deleted. If the zero point is stored in a non-active work offset, an activation
window is displayed in which you can activate this work offset directly.
Aligning
Alignment can be performed either by rotating the coordinate system or by rotating the
workpiece with a rotary axis. If your machine is equipped with two rotary axes and the
"swivel" function is set up, you can also align an inclined plane.
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
● Correcting the work offset rotates the workpiece coordinate system, which should align
You are supported by one or two activation windows when you position the rotary axes (see
Corrections after measuring the zero point (Page 111)").
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.
