Setting the workpiece zero

Functionality
The "Set the workpiece zero" function can be used to specify the reference point for
machining the workpiece.
Typical application/procedure:
1. Parameterize all the machining steps (cycles) for the workpiece in relation to a "virtual
2. Clamp the blank.
3. Scratch the relevant surface which corresponds to the "virtual zero point".
4. Use the "Set WO" function to adapt the workpiece coordinate system to the
Additional information
The following operations are performed automatically when you select softkey "Set WO":
● The work offset is automatically calculated according to the current axis position in the
● This will also set the position displayed for the longitudinal axis (Z) to 0.000, as this
● If the workpiece zero is reset, the value "0.000" will be automatically entered in the NC

memory as the basic offset. The workpiece coordinate system display will change to
reflect this.
DANGER
Notice: Setting the workpiece zero affects the absolute machining position of all
machining steps that have been parameterized in the controller!! -> All machining steps
will now be performed in relation to the zero point that has just been set!!
Setting/resetting the workpiece zero without due care and attention can result in serious
damage to the tool, workpiece or machine!!
