Tool offsets
The screens initially include the active tool T and the active offset number D for the target of
the measurement result entry. A different tool can be specified by the PLC via the interface,
or the user can enter a different tool T and/or offset number D.
Note
If a tool or offset number different to the active values has been entered, this must first be
made known to the NC for working after measurements have been made with this tool/tool
offset, e.g. by programming and start in MDA mode. Only then can the control unit calculate
the correct tool offsets.
A tool length compensation is automatically entered into the GEO component of the
active/specified tool offset D of the active/specified tool, and the associated "wear" and
"adapter" components are deleted.
When measuring the cutter radius it is assumed that no further offset is applied to the axes
of the cutter radius level (values in the axes of the "adapter" component and GEO lengths 2
and 3 are equal to zero). The result for the radius is entered in the "geometry" component.
The associated "adapter" and "wear" components of both axes of the level are deleted.
Probe
The tool measuring probe is a touch probe at a fixed location or is swiveled into the working
area by means of a mechanical device. If the probe plate is of rectangular design, the edges
should be aligned parallel to the axis. The tool/calibration tool is traversed against the
measuring probe. The probe must be calibrated before a measurement is taken. This means
that the precise probe triggering points in relation to the machine zero are known.
Preparation, probe calibration
● Select JOG mode.
● The following values should be entered in the opened window via the "Settings" softkey:
return plane, safety clearance, JOG feed, variable increment and direction of rotation of
the spindle for general use in JOG and for tool measuring.
● The following value must be entered in the window which opens when pressing the
"Probe data" softkey:
–
Feed for automatic probe approach in the measuring program.
– Probe triggering points (the values are set during calibration).
If the precise values are known, they can be entered manually. The probe does not
then need to be calibrated).
