– Tool Compensation (VUE, 200S, 300S)
Easy setup with probing functions
A very useful accessory for datum setting
is the HEIDENHAIN KT edge fi nder: Simply
move the edge fi nder toward a side of the
workpiece until the stylus defl ects. The
counter automatically stores the exact
position, taking into account the direction
of approach and the radius of the stylus. In
milling machine mode, the 200S and 300S
digital readouts offer the following probe
functions:
Workpiece edge as reference line•
Workpiece centerline as reference line•
Circle center as datum•
For electrically conductive workpieces,
these functions are also possible with an
edge fi nder with contact triggering to
ground.
Datum fi nding with the tool
The probe functions can also be carried out
with the tool.
Tool compensation for milling machines
The ACU-RITE digital readouts save tool
data in a tool table, i.e. diameter and length
of the tool used. The data can come from
preset tool or be measured on the
machine.
When positioning in distance-to-go mode,
the readouts take the tool radius (R+ or R–)
in the machining plane into account and
consider the tool length (¹L) in the spindle
axis.
Determining and storing tool
compensation values on lathes
You can store the data for the tools you
insert in the turret or quick-change holder in
the tool table:
Enter the tool position directly when •
turning the fi rst diameter, or
“freeze” the current axis position value, •
retract the tool, measure the turned
diameter and then enter that value.
Changing datums
If you change the workpiece or the
workpiece datum, you can fi x the new
datum without having to change the stored
tool-offset values. The tool data are
automatically referenced to the new
datum.
