3 Operating Sequences 09.91
3.1.8 Axis synchronization
Case 1: The tool system 1 axis and the tool system 2 axis have the same offset. Both axes
are traversed synchronously after you have pressed the traverse key for the leading
axis (tool system 1).
Case 2. The tool system 1 axis and the tool system 2 axis have different offsets. You can
only eliminate offsets by traversing the axes separately. Press the appropriate
traverse keys on the machine control panel (see the note in the box on this page!).
Case 3: Press “NC start” and the offsets are eliminated simultaneously on all axes.
By offsets we mean all additional differences in axial position between the machine zero and
the workpiece zero, which are not contained in the position instructions of the part program.
The following four offsets exist separately for the leading and the following axes:
– settable ZO G54-G57
– external ZO
– DRF offset
– PRESET offset.
If your machine control panel does not possess traverse keys for the tool
system 2, please consult the machine manufacturer.
Note:
If “axis synchronization” is selected, the following axis is always traversed together with the
leading axis (tool system 1), as long as the movements are programmed!
