83
Calibrating the Sensor to Reference Point
The figure beside shows the interpretation of
CONTACT parameters.
Let us examine the following example.
Place a tool, the overhang of which is known
in the tool holder. The tool overhang is
indicated with
X
T
, Z
T
on the diagram below.
Execute an automatic tool length measure-
ment as discussed in the previous chapter.
On the diagram it is in directions X–, Z–.
Read the selected X, as well as Z offset reg-
ister values indicated with
X
(–)
, Z
(–)
on the
diagram. Calculate and enter the values of
the CONTACT parameter with the help of
the following equation:
CONTACTX– = X
(–)
– X
T
CONTACTZ– = Z
(–)
– Z
T
The procedure can also be applied for
the other buttons.
